Zhou Dongyu’s swollen face on Weibo, how about pulling wisdom teeth, so terrible?

When it comes to the pain of adults, pulling wisdom teeth is definitely on the list. When it comes to pulling wisdom teeth, everyone will automatically think of: pain, swollen face, drinking porridge to live. Zhou Dongyu had previously sunburned his face after pulling out his wisdom teeth, and it was very swollen, and he could not laugh at himself. There is also a celebrity in the wisdom tooth world in the entertainment circle. He is Liu Xianhua, and everyone is no stranger to him. The “Longing for Life” he participated in a while ago has also received a high degree of attention, and its performance has made netizens have many Praise won’t stop. Before that, he had participated in a variety show in Korea. Among them, his face was very swollen after pulling out his wisdom teeth. Netizens also felt like a bear. It was because of this matter that he received a lot of netizens. Onlookers have to say that Wisdom Tooth really helped him a lot. So let’s discuss today, is it really terrible to pull wisdom teeth? 1. Just after the tooth extraction, why didn’t the doctor let me spit? When you have extracted your teeth, the doctor will tell you that you can’t spit, you can only swallow it in, but this water is mixed with blood, it’s really uncomfortable to swallow…the dentist has you doing this, of course, for his reasons La! A tooth extraction socket will be formed in the mouth after tooth extraction, and a blood clot will form after half an hour. The blood clot protects the wound and accelerates the healing of the tooth extraction wound. The recovery of the tooth extraction socket starts from the blood clot. About 24 hours after the tooth extraction, the local “fibroblasts” have just grown from the wall of the alveolar bone to the blood clot, and slowly become a bloody “flesh”- -Granulation tissue. Over time, this piece of “flesh” will eventually calcify into normal bone tissue, fill in the “pits” on the bone, and complete the recovery of the tooth extraction trauma. &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. But the growth of blood clots requires a process. The freshly coagulated blood clot has a tender texture like tender tofu. It can also be easily destroyed. If you spit saliva or gargle on the day of tooth extraction, it will cause negative pressure in the oral cavity to easily spit out the blood clot, resulting in more bleeding. The most terrible thing is that the wounds without the blood clot protecting the tooth extraction will become inflamed, and it is easy to form dry groove disease and produce severe pain! Even the ears and temples on the same side of the tooth extraction. Therefore, you are not afraid of bleeding after tooth extraction, but you are not afraid of bleeding! 2. After pulling out wisdom teeth, how do I know if I have dry socket? The teeth will not heal without blood. After the tooth is extracted, the blood clot falls off and the alveolar bone is exposed, showing a dry surface and exposed to the oral cavity filled with bacteria. The bone wall infection is dry socket. So, how to judge whether you have a normal postoperative reaction or dry groove? We should pay attention to the following key points: ① The time when the pain appears. The pain of dry groove is not the pain that occurs immediately after tooth extraction, but the severe pain that occurs after 3-4 days. The symptoms mentioned above do not need to be nervous two days before the wisdom teeth are removed, and the development of symptoms can be observed. ② painful area. If it is limited to the extraction socket, it may only be a postoperative reaction. If it is accompanied by radioactive peripheral pain, it may be swollen and painful to the ear-temporal area, lower jaw, and even the lymph nodes, so be careful. ③ Observe whether there is any smell in the mouth. Dry troughs or empty extraction sockets will have corrupt tissues and be accompanied by a foul smell. If you suspect that you have dry socket, please seek medical treatment immediately. The doctor will debride and apply medicine to relieve pain. If the treatment is not timely, the course of the disease can be extended for more than half a month. Infection secondary to dry groove disease may also cause osteonecrosis, osteomyelitis of the jaws, and even septicemia caused by systemic infection! &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.3, what should I pay attention to after removing wisdom teeth? Face swelling after wisdom tooth extraction is a normal postoperative reaction, don’t worry too much, and postoperative swelling reaction can occur anywhere in the body, but because the maxillofacial region is the exposed part of the body, plus loose tissue and rich blood vessels, the swelling reaction is often Is more obvious. It should be noted that tooth extraction wounds are very fragile, and smoking should be avoided within 7 days after surgery. Some patients think that “Liquor can cure wounds and sterilize, and gargle with Liquor must help wound healing!” But the doctor just wants to tell you that these are crooked! Reason! evil! Say! Tooth extraction is also a huge body cost

There is no better time for orthodontics than in 2020

Classmate gathering, OMG! How could she change so much? “Have you had a facelift? Where did you do it? Does it hurt?” When you found someone seemed prettier than before, everyone started coaxing: “Who is sure to have a facelift!” The answer was: “I swear, I just The whole teeth just “what changes does the face have? Don’t believe it, it is true that the correction case proves to be the case. Orthodontics is to make the face look better, not to destroy it. Face shape is an important reference standard for orthodontics. Several questions about normal dental orthodontics 1. Missed the “best time”, will it be too late to be corrected in adulthood? Many correction patients will have the same confusion: it is not young, is it too late to make corrections? Adulthood means that the bones have formed and can no longer be changed? Actually not at all! Alveolar bone is the only bone in the body that is constantly being reconstructed and transformed. The movement of teeth is carried out throughout life, and it will move due to factors such as eating habits. Alveolar bone, the bone that orthodontics depends on, gives it a force and can move with it. Therefore, correction can also be performed after adulthood. There is no age limit for orthodontics, as long as the periodontal health. However, for some special cases, such as osseous reflexes (dibaotian, buck teeth, etc.), early intervention treatment is recommended around 3 years old (specifically depending on growth and development and dental conditions). Since the bones are not completely shaped during the growth and development of the children, we can promote/inhibit the development of the children’s jaws through interventional treatment and guide the normal growth of the craniofacial surface. If the maxillofacial growth is shaped, it is difficult to achieve the desired results by orthodontics alone, and orthognathic treatment is still required. If the teeth are uneven and the dentition is crowded, both adults and children can be treated, but the plan will vary from person to person, and usually the treatment of young people in the growth and development period will be more effective. “The purpose of correction: 1. Improve face shape, improve smile; 2. Adjust occlusion, improve health; 3. Remove deep cover and deep coverage, crowded dentition. Orthodontics is professionally called “orthodontics”, mainly through various The orthodontic device adjusts the coordination between facial bones, teeth, and nerves and muscles of the maxillofacial region to achieve balance, stability, and aesthetics of the oral and jaw system. Orthodontics relies on orthodontics worn inside or outside the oral cavity. , Alveolar bone and jaw bone apply appropriate “force” to make it physiologically move, so as to correct the wrong jaw deformity.” 2. Adult correction, what issues should be noted? ① Pay attention to periodontal problems. Periodontitis can damage the alveolar bone and affect the orthodontics. Adult correction requires periodontal examination and evaluation. If the situation is serious enough to affect the correction effect, the treatment needs to be stabilized before correction. ② Adult correction time is slightly longer. Because adult growth and development have been basically completed, the metabolic rate is slower, alveolar bone reconstruction is relatively slower than that of adolescents, and the treatment time is longer. The best time for children to correct about 8-12 years old is generally one year to one and a half years. Adult correction usually takes one and a half to two years. Therefore, adult correction can not be rushed to achieve success. If it is done step by step, it can still achieve good results. ③ Pay attention to the regular inspection of oral hygiene. If the traditional steel wire correction method is used, oral cleaning is relatively troublesome during correction, and you need to brush your teeth carefully, otherwise it may cause gingivitis and caries. Orthodontics is a process, with different plans for tooth movement at different stages, so regular follow-up visits are required. If you do not return for a long time, it may cause the teeth to move uncontrollably, which will affect the correction effect or the correction time. 3. Adults tend to rebound after orthodontics? Will the teeth become loose? Adults need to wear the retainer on time after orthodontics, and regular review of the retainer can avoid rebound. Some patients feel that their teeth will become loose during orthodontics, which is normal within a reasonable physiological range. After the correction is completed, after a period of maintenance, the teeth will regain their previous stability. Dr. Zhou’s correction case: Ultra-high angle tooth extraction referral case Difficulty factor: 5 stars first removed four No. 4 teeth in the outpatient hospital. Four months after correction, the chin was more retracted, the chin muscles were more tense, and the occlusal plane was clockwise. Spin. So I referred to my side, re-designed the plan, increased the number of anchors, and changed the position of anchors. The correction plan hits 9 anti-nails, lowers the front and back teeth as a whole, and rotates the mandible counterclockwise in two and a half years, adducting the whole, making the chin more warped. The previous wrong way to make the retracted chin more retracted, we have to help her return to the previous state, and then make new adjustments to achieve the final perfect effect, so the second time

How to maintain dental implant for a long time?

  Dental implants are also called artificial dental implants. They include two parts: the lower supporting implant and the upper dental restoration. They are not really natural teeth. In layman’s terms, dental implants are implants made of artificial materials in the alveolar bone of the missing tooth area by means of minor surgical operations, which are used as artificial roots, and then used to repair missing teeth.  Dental implants are generally divided into two steps: the first implantation of artificial roots. The second time is to insert fixed teeth on the artificial roots that have been stabilized. Before conventional dental implants, the doctor will perform anesthesia for the patient, which is a minimally invasive surgery. There will be no pain during the entire operation. According to individual reactions, some people may feel pain and swelling within two or three days after the operation, but it is completely within the tolerable range, does not require rest, and does not affect work.  Advantages of dental implants  1, can prevent the absorption of alveolar bones  After tooth loss, the absorption of alveolar bones will proceed quickly, and the jaw bone will shrink significantly. Dental implants can reduce the absorption of alveolar bone and play the role of maintaining alveolar bone.   2. No damage to other teeth.    Repairing operation like the bridge method, you must wear off two healthy teeth on both sides of the missing tooth, which will reduce the life of the tooth. Artificial dental implants are implemented independently, so there is no adverse effect on the surrounding teeth.  3. Restoring the masticatory power. If the maximum chewing ability of healthy natural teeth is regarded as 100, the chewing power of partial dentures is 25-30, the complete dentures are 10-15, and artificial implants can exert 80-90 strength. How to maintain dental implants for a long time?    1. How to make dental implants last longer after regular follow-up visits? Generally, visits are conducted every 6-8 months, and special instruments are used to remove plaque, soft dirt and other harmful substances attached around the implants. Avoid inflammation around the dental implant. 2. Avoid biting hard objects. Dental implants have incomparable good performance in traditional dentures. Patients can use dental implants like normal teeth, but they should also avoid biting hard objects like real teeth. Beer bottles, bite walnuts, etc.   3. The dental implants are clean and hygienic    Daily brushing and gargle are the most important. For toothpaste and toothbrushes, toothbrushes with soft bristles should be selected. The relationship between the tooth body and periodontal of the implanted tooth is different from that of natural tooth. It is necessary to clean and protect the surrounding area of ​​the implanted tooth, which can extend the life of the implant.

How to choose the appliance?

   At present, the types of orthotics used in the market can be basically divided into three categories: fixed orthotics, active (recessive) orthotics, and lingual (fixed) orthotics.    These three types of orthotics are the patients’ most choices. However, the treatment plan obtained after communication with the doctor must be based on personal circumstances and demands.  1Metal bracket correction  Metal bracket correction belongs to fixed correction.   Mainly use metal brackets as appliances, use metal ligature wire or rubber ligature ring to ligate, the price is relatively moderate, and it is suitable for almost all people and all types of dental jaw deformity. Main disadvantages:    1. Occasionally, the metal ligature wire ligation may lift up, and the phenomenon of irritating the mucous membrane may scratch the wall of the mouth.    2. The metal bracket is exposed, and the appearance is lacking.    3. The tooth surface is relatively difficult to clean and easy to cause teeth Face demineralization requires sufficient attention.   2 Self-locking bracket correction    Self-locking bracket correction belongs to fixed correction. It is an improvement made on the basis of metal brackets, that is, the technology of using a self-locking device such as a sliding cover to fix the arch wire in the groove of the bracket, without the need for traditional metal ligature wire or rubber ligation ring, the bracket is small, It is relatively easy to keep the teeth clean and other advantages.   Main disadvantages:    1. It is easy to align at the initial stage. In the later stage of square wire, the arch wire may sometimes be difficult to place.    2. The movement of the tooth root is relatively poor (metal bracket).    3. The metal bracket is exposed, lacking in appearance.  3Ceramic bracket correction  Ceramic bracket correction belongs to fixed correction.  Because the color of ceramics is close to the natural color of teeth, correction in this way has a certain concealment. It belongs to semi-invisible correction and is suitable for most dental jaw deformities and people.   Main disadvantages:    1. The volume of ceramics is often larger than that of metal brackets.    2. Ceramic brackets are brittle and easy to break when used.    4 Stealth correction without brackets    Stealth correction without brackets belongs to active correction.   is also called invisible transparent orthodontics. It is a technology that uses a brand-new 3D digital computer technology to tailor a series of nearly imperceptible transparent dental trays to complete the entire correction treatment. Comfortable to wear, easy to pick and pick, especially suitable for beauty lovers.   1. The cost of appliance is more expensive. 2. 20 hours of wearing time per day, otherwise the corrective effect cannot be achieved, so it is not recommended for young people with poor self-discipline.    2. Severe occlusion is not good, severe bone tooth deformity is not suitable for 3. Loose teeth, periodontal Those who are seriously ill or have pathological changes in the roots of the teeth are not suitable.    4. Those with permanent teeth that are not fully developed in adolescents are not suitable.   Here is a special reminder: When correcting, you must follow the doctor’s advice. The patient should not blindly choose or buy braces online for correction, so as not to affect the correction effect and progress, or even cause teeth inflammation and necrosis.

Count the three sins of missing teeth

  Sound happiness is full of children and grandchildren, and it is full of joy. Silent happiness is a good bite, and enjoy the good luck. Being able to have a tidy and healthy tooth, being able to eat and drink well is a kind of happiness in old age. However, the problem of missing teeth made their life difficult in their later years. It is a pity to face all kinds of mountain and seafood tastes.  Many elderly people think that lack of teeth is normal. They think that tooth implantation is very troublesome and costly. They refuse to repair, and they are unwilling to confess pain with young people.   In fact, long-term tooth loss will not only lead to deterioration of chewing function, restricted diet, lead to indigestion, nutritional deficiencies, decreased resistance, and seriously affect health. The problem of missing teeth cannot be solved, and the old age can’t be happy.   Therefore, if there is a missing tooth problem, it must be repaired as soon as possible.  The first one is that tooth deficiencies seriously affect the health of the body.   Teeth deficiencies cause difficulty in eating, which is probably well known. When you are old, you just want to enjoy it-enjoy life and thought, experience and observation, enjoy memory and hope, enjoy friendship and free freedom… However, for the missing teeth, even delicious meals Can’t enjoy it, how to enjoy life? The second is the collapse of the face caused by missing teeth. After the loss of multiple teeth, the support of the teeth between the upper and lower jaws is lost, and the stimulation of the normal chewing force is lacking. The alveolar bone or the entire jaw bone gradually degenerates and absorbs, the height of the lower part of the face becomes shorter, and the muscles of the cheeks and surrounding muscles relax. Lips and cheeks are recessed, facial deformation and wrinkles increase, and the whole person looks old.   The third is the lack of teeth affecting health. When individual teeth are missing or dentition is missing, chewing efficiency is reduced or lost, saliva secretion is reduced, gastrointestinal motility is slowed, unchewed food enters the gastrointestinal tract, and the burden of the gastrointestinal system is increased, resulting in gastrointestinal tract Dysfunction, which affects the body’s absorption of nutrients. In severe cases, the body may have diseases of the digestive system. The sooner the teeth are planted, the better the body will say, “health is eaten”, but people are old and have no teeth, where can they eat health? Dental implants are known as “the third pair of human teeth”. It has the advantages of wounding adjacent teeth, minimally invasive safety, beautiful and comfortable, strong chewing function, long-lasting effect, etc. It is trusted by patients with missing teeth.

Does it matter if the gap between baby’s deciduous teeth becomes larger? How did it come about?

Does it matter if the gap between baby’s deciduous teeth becomes larger? How did it come about? The gap between the baby’s deciduous teeth is actually due to the normal development of the jawbone, because the number and size of the teeth are unchanged. If the jawbone is developing, the gap will gradually increase, and parents should not worry too much. &nbsp. Moreover, it is a good phenomenon to have a physiological gap between the deciduous teeth of the baby. If there is no gap or the gap is small, it should be taken seriously. Because the permanent teeth are much larger than the deciduous teeth, if the baby’s jaw does not develop enough and the gap is not enough, after the permanent teeth grow out later, there may be crowded dentition and erupted teeth. Therefore, parents should usually give their babies coarse grains and coarse fiber food to develop their jaws.

Do you want to wash your teeth? How often do you wash your teeth? You will understand after reading this!

&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&bb&nbsp.&nbsp.&bb&b &nbsp.&nbsp. Why wash your teeth? &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.Teeth cleaning is a method for thoroughly cleaning plaque and calculus, but many friends think that their grandparents have not washed their teeth and have not lived their entire lives. . As long as the teeth can be used normally, the rest is right~&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. In fact, this is a wrong understanding. In the past, dental technology was not so advanced, and many people had broken teeth It cannot be repaired, but now that this condition exists, why not make the teeth healthier? (Not too expensive)&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.b&b&nbsp.&nbsp. Take a look at this friend )▼What are the benefits of washing your teeth? &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. Although we brush our teeth every day, we cannot clean our teeth thoroughly. Because there is not a tight adhesion between the gum and the root surface, but there is a shallow groove of 0.5-2 mm, called gingival groove. &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. Food debris tends to accumulate in the sulcus, which is an area that is difficult to clean thoroughly. &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. After food accumulates, it is easy to form plaque with saliva in the mouth and attach to the surface of the tooth, which will become calculus over time. These bacteria can cause gingivitis and teeth. Zhou Yan, hemorrhage, and bad breath will eventually cause the teeth to loosen or even fall off. &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. And tooth washing is to remove these calculus and plaque attached between the tooth neck and gingival sulcus by various instruments to reduce gingivitis 1. The inflammation of periodontitis. &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. This depends on your personal oral problems. Some people have poor oral hygiene and usually do not pay attention to care. They only wash the tooth surface for two or three months. They are all plaque and calculus, so they must still come to the hospital for review.  &Nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. And some people maintain good oral hygiene, may wash in two or three years

What to do if your teeth are sensitive

Teeth allergy, also known as allergic dentin or dentin hypersensitivity, is caused by external stimuli such as temperature (cold and hot), chemical substances (acid and sweetness), and mechanical effects (friction or biting hard objects) caused by teeth Sore symptoms. It is characterized by rapid onset, sharp pain, and short duration. Hypersensitivity of teeth is not an independent disease, but a symptom common to various dental diseases,
Especially tooth abrasion, periodontitis and wedge-shaped defects of teeth.
Tips for alleviating tooth allergy:
Normally, you should choose toothpaste and health toothbrush with high-quality friction agent, and brush your teeth in the correct way to avoid tooth wear.
If small decay or small cracks appear on the teeth, apply toothpaste with repair function.
If tooth sensitivity occurs, desensitized toothpaste should be used to reduce pain. This is suitable for people with more allergic teeth and less clear allergic sites and mild allergy symptoms.
Pay attention to brushing your teeth for a certain period of time, such as 2 to 3 minutes, so that the active ingredients in the toothpaste have time to affect the diseased parts of the teeth. And brush your teeth frequently, especially before going to bed. You should avoid eating after brushing your teeth before going to bed.
Those with severe symptoms should promptly see a dentist for examination and treatment, generally including laser desensitization or drug desensitization.

The VC small class starts! Come to the dentist to understand the veneer veneer!

The VC small class starts! Come to the dentist to understand the veneer veneer! &quot.Tooth white is pretty pretty, beautiful teeth first&quot., when a beautiful woman with white skin wins snow, she smiles with a black, black, yellow and yellow teeth when she smiles! and so! What is more important than plastic surgery is “dental beauty”-dental veneers. Today Vincent will give you some knowledge of dental veneers! (Knock on the blackboard) 1. What is a tooth veneer? The veneer restoration is to apply the bonding technology to cover the defected tooth body, colored teeth, discolored teeth or deformed teeth and other affected parts of the tooth with no grinding or less grinding, to restore the teeth. A method of repairing normal body shape or improving its color. Porcelain veneer can be simply understood as a thin ceramic restoration that is retained by bonding. It is a less invasive restoration technique than the full crown, which is more in line with the future direction of oral restoration. 2. Who is suitable for dental veneers? 1. Cracks and defects of teeth caused by enamel dysplasia and mild caries; 2. Discolored teeth, such as mild tetracycline teeth and dental fluorosis; 3. Abnormal tooth shape, Too small teeth, too short teeth, worn teeth, etc.; 4. Mild misaligned teeth or interdental teeth, patients are reluctant to receive orthodontic treatment; 5. Hereditary yellow teeth. 3. The advantages of dental veneers: 1. Provide a natural appearance of teeth; 2. Good tissue compatibility between gums and porcelain; 3. Porcelain veneers are not easy to stain and dye; 4. Color of porcelain veneers can be selected: for example Make yellowish and dark teeth white; 5. The veneer provides a conservative treatment to change the color and shape of the teeth, not only does not require a lot of tooth preparation like the full crown, but also provides more powerful and more Aesthetic choice. 4. How to maintain the dental veneer? Go back to the doctor every year to check the tightness, bite, edge wear; maintain oral hygiene, wash your teeth once a year to reduce the impact of calculus on the veneer; do a polish on the veneer to prolong the life and avoid falling off, discoloration . Those in need must find a professional stomatologist, do a comprehensive inspection, and then choose the appropriate whitening method according to their own situation. If you have any dental problems, you can directly send a letter to Dr. Vincent

How to maintain after orthodontics

How to maintain the state of the newly corrected teeth after orthodontics, or how to maintain the state of the young teeth, because with the loss of time, everyone’s teeth state will also be aging, and certainly not when young In the same way, the teeth move forward and downward continuously, so how to maintain is a matter for everyone who does the correction. How to maintain it, from the perspective of the history of maintenance, the viewpoint of occlusion stability; the viewpoint of apical basal bone stability; the viewpoint of mandibular incisor stability; the muscle stability. &nbsp. Retention of anti-jaw correction. A 2010 study reported that 40% of orthodontists would routinely use mandibular lingual retainers, while 28% would use Hawley retainers, and 18% recommended the use of transparent pressure film retainers. For the upper jaw, 58% of doctors use Hawley retainers, while 30% recommend pressure-retaining retainers. &nbsp.&nbsp.

What should I do if I keep bleeding after tooth extraction?

&nbsp.&nbsp.&nbsp. A few days ago, a report entitled “Men who bleed for more than 10 days after pulling out their wisdom teeth” was reprinted by many websites and attracted wide attention. Many people who have pulled out their wisdom teeth said that they were shaking and thanking themselves that they were fine. Many people who had never pulled their wisdom teeth shivered, saying they did not dare. &nbsp.&nbsp.&nbsp.&nbsp. Let us briefly review this incident. The patient Liu, male, 26 years old, had his wisdom teeth removed at the Zhongnuo Stomatological Hospital in Changsha on May 25, and he subsequently bleeds. He communicated with the doctor on WeChat during the period and did not go to the hospital for further treatment until June 4 The patient was diagnosed with a suspected acute leukemia, cellulitis of the maxillofacial region, sepsis, and lung infection. The patient was subsequently rescued due to concurrent cerebral hemorrhage and cerebral hernia. . &nbsp.&nbsp.&nbsp.&nbsp. In fact, deaths due to tooth extraction are extremely rare, and tooth extraction will not be a direct cause of death. Serious complications during tooth extraction are often caused by systemic diseases in other aspects of the body, such as heart disease, blood diseases, and malignant tumors. So we still have to calm down our minds. When it comes time to extract teeth, we have to resolutely pull out, and we should not waste food because of choking. Next, I want to talk about what should we do if the bleeding continues after tooth extraction. &nbsp.&nbsp.&nbsp.&nbsp. The best treatment is prevention. Doctors will fully understand the patient’s physical condition before the operation, assess the possible risks, and try to avoid dangers. For example, for the complication of bleeding after tooth extraction, we usually have to carry out the following preparations: 1) ask whether the patient has systemic diseases such as high blood pressure, hemophilia, leukemia, etc. 2) ask whether the patient takes aspirin, polyvi, etc. Anticoagulant drugs 3) Preoperative blood test routine and coagulation routine, check whether the patient’s coagulation function is normal 4) Take X-ray film or CT, check the relationship between tooth root and peripheral neurovascular 5) Check whether the soft tissue around the tooth has inflammation, whether it is easy Bleeding&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. These are all risk factors that may cause bleeding after tooth extraction, we must carefully investigate. Therefore, when you go to pull wisdom teeth, the doctor repeatedly asks you if you have various diseases, whether you take any medicine, and then let you take a blood test for various tests. Don’t think that the doctor is deliberately making you difficult. We do all of these. In order to ensure the safety of the operation, I hope everyone understands and cooperates with the doctor. &nbsp.&nbsp.&nbsp.&nbsp. Many years ago, our department had a young patient. The patient actually had hemophilia, but he did not know it. At that time, we did not have all patients routinely check blood before surgery. Therefore, no problems were found in advance in patients’ coagulation. After the wisdom tooth extraction, the patient had more bleeding in the extraction socket. We filled the extraction socket with iodoform gauze and sewed it tightly. The bleeding stopped temporarily. One week later, he had bleeding in the extraction socket when he removed the thread, so he was tested for coagulation function, and the patient was found to have hemophilia. The lack of coagulation factors caused abnormal coagulation. After finding the cause, supplement it with the corresponding coagulation factor, and the problem of bleeding is solved. &nbsp.&nbsp.&nbsp.&nbsp. In addition, patients with high blood pressure, leukemia or taking anticoagulant drugs may cause postoperative bleeding. You must tell the doctor truthfully when you visit the doctor. &nbsp.&nbsp.&nbsp.&nbsp. Under normal circumstances, the bleeding in the extraction socket will coagulate within half an hour, the blood clot will completely clot in about 2 hours, and the blood clot will begin to organically form granulation tissue in 24 hours. Therefore, after tooth extraction, we will tell the patient to bite the gauze for 40 minutes, and then eat two hours after the operation. It is advisable to eat cold soft food. Do not brush your teeth and rinse your mouth within 24 hours after the operation to avoid licking the wound. These measures are for Protect blood clots in extraction sockets to prevent postoperative bleeding. &nbsp.&nbsp.&nbsp.&nbsp. Of course, there is no problem with all of the above, and some patients will have bleeding after tooth extraction.

Is your bite inherited?

&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&bb&nbsp.&nbsp.&bb&nbsp. What kind of experience is it? &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&bb&nbsp.&nbsp.&bb Old hit the front teeth”&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.”My mouth is closed and the teeth are too far out&&nbsp.&nbsp.&nbsp.&bb&nbsp.&b “My teeth are neat, but the mouth shape is convex”&nbsp.&nbsp.”I can’t smile when taking pictures, and the teeth flew out when I smiled”&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. Why do you have dents? &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. The formation of “buck teeth” has innate factors. One is genetic inheritance, that is, parents have “buck teeth”, and the chance of children having “buck teeth” is relatively high High; &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. The second is human evolution. As food becomes more and more refined, the jaw bones become smaller and smaller, but the number of teeth does not decrease, which may cause crowded dentition or Protrusion, the manifestation of the protrusion is “bucket”, which is also a particularly important reason. &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. Acquired bad habits such as mouth breathing, tongue sticking, lower lip biting, and adult sucking habits may also be the cause of the disease. &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&bb&nbsp.&nbsp.&bb.n &nbsp.&nbsp.&nbsp.&nbsp.How to treat buck teeth? &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. “Buck teeth” are divided into odontogenic and bone-derived, odontogenic “buck teeth” are simple tooth protrusions that can be corrected by orthodontics , The timing of correction can be widened, and some can even be delayed into adulthood. Of course, the sooner the correction effect is better, the impact on psychology and life is less; &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. &nbsp. The bone-derived “buck teeth” are the protrusion of the jaws, or the protrusions of the jaws and teeth. At this time, the treatment is relatively difficult, and often requires orthodontic orthognathic combined treatment. &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&n

Seven myths about dental implants

Dental implants are also called artificial dental implants. They are not really natural teeth, but medically designed pure titanium with high compatibility with human bones through precision design, manufactured into a shape similar to the root of the tooth, and then replanted. Into the alveolar bone of the missing tooth area. In our daily lives, we have many misunderstandings about dental implants, leading to various adverse consequences that need to be guarded against.  Misunderstanding    All the problem teeth need to be removed and implanted to solve the problem: Although implants have many advantages, if the real teeth can be retained by treatment, treatment should be adhered to, rather than pulling out every time. Misunderstanding: Both teeth are lost. It is impossible to “seeding” teeth again: Although some of the alveolar bones will be absorbed after the teeth are lost, there are still remaining alveolar bones or jaws that can be “titanium nailed”. Implants are “titanium nailed” on these remaining alveolar bones or jaw bones as artificial roots. In addition, pure titanium has good biocompatibility with bone tissue, bone cells will combine with titanium, grow on the surface of titanium nails, and firmly bind together. Misunderstanding three: implanted teeth = porcelain teeth on natural roots to solve puzzles: implanted teeth are made on natural roots. Porcelain teeth are medically called “pile crown teeth”, which belongs to the category of dental restoration, and implanted teeth are dental implants. category. Therefore, dental implants are implanted without roots, and artificial roots are required.  Misunderstanding four   Dental implants once and for all   Understand: The service life of dental implants can be at least 10 years, of course, this is related to everyone’s usage habits and protection methods. Generally speaking, the pure titanium artificial tooth root after implantation is generally stable and does not need to be replaced, but if the dental crown of the implant is not well protected, it may need to be replaced.  Misunderstanding 5  Once you “seed” your teeth, you will have to “see” your mouth. Experts point out that it is not necessary to “seed” every tooth removal area once you have chosen “seed” teeth. For the elderly who have lost a whole row of teeth or lost a lot of teeth, they only need to make a small amount of dental implants as a fixed support “bridge pier”, and the entire row of dentures will function firmly on the “bridge pier”.  Misunderstanding six   It takes 3-6 months to complete the “seed” teeth: now the “seed” teeth can be completed once. In the past, the “planted” teeth had to be pulled out of the damaged roots, and the artificial roots could only be implanted after three months, and the crowns could only be installed after another three months. But now, in some cases, the artificial root and crown can be implanted immediately after the tooth is removed, which is 6 months shorter than before!    Misunderstanding seven “seed teeth” is a terrible major surgical puzzle: “seed” teeth In fact, it is a minor operation. Now it has developed into a minimally invasive operation. There is less postoperative bleeding, no swelling and pain, and all the missing teeth can be “planted” at once. The pain and trauma are even smaller than tooth extraction.

Do well in fissure sealing to effectively prevent tooth decay

Everyone may be familiar with the ad phrase “Our goal is no tooth decay”, but do you know that the sealing of fissures can effectively prevent tooth decay? 1.&nbsp.What is fissure closure? There are some grooves and gaps on the occlusal surface of the big teeth in our mouths, called fissures. The ditch can increase the contact area of ​​the upper and lower teeth when chewing food, allowing the food to be ground more effectively. Fissure sealing is the use of a fluid filling material to “fill” the fissures on the occlusal surface of the large teeth to form a protective barrier to prevent and reduce tooth decay. The sealing material “fills in” the groove on the surface of the tooth 2.&nbsp.Why do we need to close the groove? When the children’s big teeth just sprout, the fissures in the fissures are deep, and it is easy to leave food and accumulate plaque. But because children are not skilled enough or not careful enough, it is difficult to clean the fissures. In the long run, large teeth are more prone to tooth decay. Children are in the critical stage of growth and development, and big teeth are the main force for us to chew food. If the big teeth decay, it will hurt and will be uncomfortable, which may affect the eating, which will affect the growth and development of the children, especially the normal development of the maxillofacial region. The operation of fissure sealing is simple, the process is easy and painless, and it is safe and effective, just like putting armor on the teeth, it is very meaningful for preventing tooth decay. 3.&nbsp.When do I need to do fissure sealing? Generally, you can do it after the big teeth sprout, the sooner the better. Deciduous tooth stage: at 3-4 years old, the baby can cooperate with oral operation; replacement stage: the first permanent molar (sixth-year-old tooth) erupts, 6-8 years old, very very important; &nbsp.&nbsp.&nbsp.&nbsp.&nbsp .&nbsp.&nbsp.&nbsp.&nbsp. The second permanent molar eruption: 12-14 years old. 4.&nbsp.After the fissure seal is done, will there be any tooth decay? of course not! First of all, after the fissure closure is done, regular inspection is required. During use of the tooth, the sealant may wear out or partly fall off. If necessary, it needs to be replaced as soon as possible. Moreover, tooth decay does not only occur in the pits and grooves. Other parts of the teeth may also suffer from tooth decay due to the lack of cleaning. Parents should know that pit and fissure closure is an effective way to prevent tooth decay, but it is far from all. We need to cultivate children’s awareness of oral protection from an early age, and teach them the methods of brushing and flossing, and check their teeth regularly. Knowing that “no tooth decay” is not just a goal, it is action!

Can orthodontics be partial?

Many small partners consult Dr. Feng and feel that they have only individual teeth that are not neat or in a bad position. They want to be corrected by local or only upper or lower teeth. Is this possible? As an orthodontist, we will treat the small partners The overall condition of our teeth is checked, analyzed, and then the correction plan is determined, and the specific situation needs specific analysis. For most tooth arrangement problems, such as irregular teeth and cracked teeth, it is not possible to do only partial. Not only do the teeth need to be neatly arranged, in close contact without interdental gaps, but also need to be aligned with the midline of the upper and lower teeth, and the gear-like “point” and “dimple” relative occlusal contact between the upper and lower teeth. It seems that the adjustment of the position of certain teeth generally requires the joint participation of the adjacent teeth and the contralateral teeth. Moreover, the dental problems seen by the buddies are often only part of all the problems of the teeth. In most cases, the orthodontist will also find some problems that the buddies did not find themselves. We recommend that through one correction, the teeth can be solved. Solve them together, and harvest a pair of teeth that are closest to perfection. Isn’t the “price ratio” higher? There are also individual cases where partial correction of teeth can be done. For example, before tooth implantation or dental implantation, the position of adjacent or contralateral teeth can be adjusted by local correction, and the posterior teeth are simply locked (the upper and lower posterior teeth are not occluded and are inclined and staggered) Local correction, and children correct individual teeth that affect aesthetic function during tooth replacement. Partial correction can only make limited adjustments to the position of individual teeth, and specific inspections are needed to determine.

Obviously to be corrected, why did the doctor want me to wash my teeth first?

Correction is to move the tooth to a better position. Before moving, we must first confirm that the tooth itself is good, the foundation of the tooth is stable, that is, the periodontal should be healthy. Therefore, before the correction starts, the tooth with tooth decay must be filled first (except the tooth to be removed in the correction plan), and the tooth with calculus and periodontal inflammation needs to be washed first. Only when the tooth and periodontal are in a healthy state can we start correction. . Tooth decay needs to be filled as soon as possible, everyone understands well, but why do you need to wash your teeth first and let the periodontal health begin to correct it? In the correction, the movement of the teeth is accompanied by the reconstruction of the alveolar bone, which requires the generation and absorption of the alveolar bone around the root to maintain a dynamic balance; and periodontal inflammation is a destructive state in which the absorption of the alveolar bone is greater than the generation. If there is periodontal inflammation while the teeth are moving, it will transform the original alveolar bone reconstruction into a more extensive destruction-based activity, which will increase the periodontal inflammation and increase the looseness of the teeth, while interfering with the normal teeth. mobile. By washing our teeth, we can remove the “pathogenic roots” of periodontal inflammation and restore the periodontal health. Moreover, the small partners who need to wash their teeth are often not clean up to the standard. During the correction process, some device parts will be more or less added to the teeth, especially fixed correction, and the teeth need to be cleaned after each meal, which will increase the necessity and difficulty of tooth cleaning. Before correction, we should help our little friends to strengthen their awareness of tooth cleaning and master the skills of tooth cleaning while washing their teeth, so that they can better maintain oral hygiene and maintain teeth and periodontal during the correction process The state of the teeth allows healthy and healthy movement of teeth.

Those things about orthodontic retainers~

After orthodontic treatment moves the teeth to the ideal position, the alveolar bone still needs a period of time to be built in place again, so that the teeth are stabilized at the new position, so the retention period of orthodontic treatment is very important. In general, we will require It is guaranteed to be maintained throughout the day and evening during the year. If there are special circumstances, or the patient itself has very high requirements for the uniformity of his teeth, it may need to be maintained for life. The position remains unchanged, and it may really need to be maintained for life, but it is not necessary to wear the retainer all day long in the later period, only need to wear it every night or overnight). Three common holding methods&nbsp.&nbsp.&nbsp.&nbsp. First of all, let’s talk about the commonly used pressure film holders in China. The laminator is relatively simple to manufacture and takes a short time. The patient can wear the appliance as soon as possible on the same day when the appliance is removed, keeping the effect good, timely and beautiful. The difference between different film holders is mainly on the thickness and elasticity of the material. At present, the most expensive film holder on the market may be regarded as the Vivera retainer. The Vivera uses the smart track material of the patent. It is more fit and more comfortable than ordinary lamination holder. But if it can be worn as required, whether it is a Vivera or an ordinary pressure film retainer, the retention function is basically the same. As for whether to choose Vivera retainers at a high price, it is actually the same as our daily purchase of various supplies. If the economic conditions allow and there is a high demand for comfort, you can choose the Vivera retainer, if there is no special It is enough to choose ordinary pressure film retainer. The lingual wire is fixed and held. In addition to the film holder, there are many kinds of holding methods/devices. Tongue fixation wire retention is currently the most commonly used and most effective method of preventing anterior teeth crowding/torsion recurrence, but the disadvantage is that it is not conducive to oral hygiene maintenance, especially it will prevent the adjacent surfaces of the upper and lower anterior teeth from being cleaned, but it is used in conjunction with interdental teeth. Brushing and punching can offset this shortcoming. The Hawley retainer is another commonly used retention method. The advantage is that it does not cover the occlusal surface of the teeth, giving the teeth a natural adjustment space, so the occlusal function will be more improved while maintaining. But Hawley retainers also have shortcomings. It has limited wrapping of teeth and there is still some room for recurrence of anterior teeth. Therefore, if there is a case of uneven twisting of the anterior teeth, short roots of the teeth, or more periodontal attachment loss before treatment, doctors often choose to use the lingual side wire to maintain the anterior teeth and cooperate with the pressure film holder or Hawley retainer. . Hawley retainer&nbsp.&nbsp.&nbsp.&nbsp. According to my observations in recent years, the common retention method used by orthodontic doctors in Europe and the United States is that adults often use the lower anterior lingual wire to retain (the lower jaw does not use lamination or Hawley retainer) With the maxillary pressure film holder, teenagers will use the upper and lower jaw Hawley retainers more. Such a retention method is justified: young people have low demands for aesthetics, and need a self-retaining, easy-to-clean retention device, while young people are still in the developmental stage, and the occlusal surface is not suitable for being wrapped, so as not to affect the development of occlusal function And perfect, so the Hawley retainer is very suitable for teenagers; adults pay more attention to aesthetics during the retention process, so the Hawley retainer is not suitable; and the mandibular anterior teeth are the most likely areas of recurrence, so it is more effective to use the lingual wire to maintain; the lower jaw The posterior segment of the teeth is limited by the clamping of the tongue and buccal muscles and the bite. In fact, it is not prone to recurrence, so you can consider not adding a retaining device in the posterior mandibular region of the mandible; The shape of the dental arch is prone to recurrence and deformation, so it is more suitable for the pressure film retainer; the retention force of the maxillary pressure film retainer is sufficient, so the anterior teeth area no longer needs to be used with the lingual wire retention; while the single jaw uses the pressure film retainer, you can do May reduce the impact on occlusion. In summary, this type of retention is an optimized retention method that fully considers all aspects and is worthy of our reference. The two retainers have different aesthetics

[Does tooth ‘occlusion’ cause difficulty in nasal breathing? 】

&nbsp. “Does teeth opening “occlude” cause difficulty in nasal breathing?” The answer is really possible. In terms of expansion, it will involve the division of labor and cooperation between stomatology and otolaryngology. So if someone goes to the otolaryngology department because of difficulty breathing and snoring, and then be referred by the doctor to the stomatology department or ask the stomatology department to consult, don’t feel strange anymore! The mouth and the ear, nose, and throat are closely related.&nbsp.&nbsp.&nbsp.&nbsp. Opening the teeth may cause nasal breathing difficulties. In fact, it is more accurate to say that opening the teeth may be related to nasal breathing. Difficulties. Teeth opening is just a manifestation, it is not the cause of breathing disorder. Therefore, whether nasal breathing difficulty is related to open occlusion depends on the reason for open occlusion. &nbsp.&nbsp.&nbsp.&nbsp. There are actually many reasons that cause the teeth to open up. It is mainly divided into two categories: “tooth-opening” and “bone-opening”. The specific diagnosis needs to be combined with oral clinical examination and x-ray examination. The clinical manifestations at first glance are not obvious, but open The reason for’occlusion’ is quite different. Vertically open the front teeth to open the front teeth. The open teeth are often caused by bad habits such as sucking foreign objects (sucking thumb, pen bit, etc.) or tongue swallowing and other bad habits. ‘Occlusion’ does not cause changes in the respiratory tract, so it has nothing to do with nasal breathing difficulties. &nbsp.&nbsp.&nbsp.&nbsp. If it is due to joint condyle absorption, abnormal posterior occlusion (sometimes related to wisdom tooth eruption), progressive increase in mandibular retraction, etc., most of the occlusion of the anterior teeth will be accompanied. With the rotation of the lower jaw backward and downward (clockwise), the anterior and posterior diameter of the airway will be squeezed and compressed to cause respiratory disorders. Vertical + horizontal forward teeth open’closed’&nbsp.&nbsp.&nbsp.&nbsp. However, some people’s jaws may not appear as vertical anterior teeth opening and closing after clockwise rotation of the mandible, may appear as upper and lower anterior teeth The front-to-back coverage is getting heavier, so some experts call our commonly used “deep coverage” “horizontal opening and closing”, which makes sense. However, whether it is a vertical anterior teeth’occlusion’ or a horizontal anterior teeth’occlusion’ caused by bone problems, because there will be abnormalities in the position of the mandible, it may be accompanied by different degrees of breathing disorder (because of this Respiratory disturbances are related to the position of the jaw, so they often get some relief when they breathe, and the patient will feel subjectively as a nasal breathing abnormality). &nbsp.&nbsp.&nbsp.&nbsp. So it is possible that anterior teeth are’occluded’ related to breathing disorders, but not all teeth are’occluded’ and there will be breathing disorders, and not all breathing disorders are accompanied by teeth Open’occlusal’. However, if there is an anterior tooth opening and an abnormal breathing function, it is likely that ENT and oral orthodontics or oral and maxillofacial surgery will be required.

Dispel rumours-Will it take longer to make corrections with an invisible appliance?

&nbsp. Many friends who want to do corrections are worried that wearing traditional appliances will affect their face value, but they are not comfortable enough and difficult to clean. On the other hand, they worry that it will take more time to wear invisible appliances, and may not reach To the desired effect. So as an orthodontist, I often need to explain the differences and characteristics of these two types of appliances. But I tend not to recommend appliances from my perspective because they are just two different types of tools and techniques to achieve my stated goals. &nbsp.&nbsp.&nbsp.&nbsp. The traditional appliance has a long history. It is a type of precision design and various elasticity through brackets (the small pieces of metal or ceramics stuck to the teeth), Hardening arch wire and various curving finely bent on the arch wire to achieve precise control of teeth. Because of its long history, its industrial design, treatment technology and theoretical system have been developed to a relatively mature treatment method today. The treatment experience handed down is also very rich. With the support of big data, a relatively accurate one can be inferred. Cases of high probability of treatment time and treatment effect. &nbsp.&nbsp.&nbsp.&nbsp. The invisible appliance, represented by invisible beauty, is a typical “black” technology of the 21st century. It relies on the innovation of materials and the development of digital technology. It is a new type of orthodontic device established and flourishing on the “shoulder” of the classic knowledge and technical system of traditional appliances. Due to the essential difference between materials and afterburning methods and traditional appliances, it is necessary to design a set of specialized treatment techniques in a more targeted way if you want to make good use of this “new tool”. The history of the development of invisible correction technology has been less than 20 years so far, but it has developed rapidly-first of all, the theoretical system of orthodontics has matured is its solid foundation, and some hardworking and intelligent orthodontists are based on this foundation. Active learning makes invisible correction technology rapid formation and maturity, and this “fast-paced” and “high demand” era makes its application and promotion more like “rocketing”. A few years ago, the orthodontic community generally believed that invisible appliances were “long treatment time” and “not suitable for deep-coated cases”, etc. In recent years, invisible appliances have been recognized by more and more orthodontic experts And acceptance, a large number of clinical cases have confirmed that invisible appliances can achieve the same treatment goals as traditional appliances with the same treatment time, and in some cases the treatment time will be even shorter. &nbsp.&nbsp.&nbsp.&nbsp. Whether using traditional or invisible appliances, professional orthodontists determine the treatment goals of a case and design the treatment plan from the same theoretical system, so there will be no big Difference. These two types of appliances are like two roads leading to the same goal, each with its own characteristics and strengths. It is the responsibility of the orthodontist to “treat according to his aptitude”. Therefore, except for special circumstances, I think that the choice of appliance can be given to the patient to a certain extent. Of course, each case is different, I will do specific personalized diagnosis analysis and treatment design according to his/her specific situation, and more pointed out the pros and cons of each appliance for patients to make their own judgments and choices . &nbsp.&nbsp.&nbsp.&nbsp. Thank you for your attention to Dr. Wen, and then I will do a little science about orthodontics for everyone, answer questions, smash rumors! If you have any special questions, please leave a message in the comment area!

Seeing dental problems from the perspective of dental structure

&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.Crown and roots&nbsp.&nbsp.&nbsp.&nbsp.From the picture above, we can see that the tooth is like a tree, growing in the alveolar bone, and the crown is exposed in the tooth Meat outside. Because the oral cavity is full of bacteria, plus the effect of our food debris, the crown is the most prone to problems. What are the possible problems with the crown? First, it may be due to caries and cavities; the crown morphology may change due to long-term abrasion caused by night molars or rough diet; the crown tissue may be disintegrated due to excessive bite force; the teeth may be broken due to external impact Wait. Dental pulp and nerves&nbsp.&nbsp.&nbsp.&nbsp. Inside the crown, we can see the red “dental nerve”, which is the pulp tissue; when the crown tissue is healthy, our dental pulp is well protected and It won’t feel anything. When the above problems occur in the crown, the first thing involved is the pulp. When the pulp is stimulated, there will be feelings of sensitivity and pain. For example, chronic or acute pulpitis caused by deep caries may cause chronic or acute pain; trauma may cause pulp necrosis, and the teeth gradually become gray, but there is no obvious discomfort. After the tooth is broken, the pulp is directly exposed, and the sensation of stimulation is more obvious. &nbsp.&nbsp.&nbsp.&nbsp. Looking from the dental pulp towards the root of the tooth, it can be seen that the cavity of the pulp is gradually shrinking, and finally the apical foramen and the nerve inside the bone are connected together. This anatomical structure is the nerve nerve stimulation and conduction of the tooth To the basis of the brain, when the pulp is inflamed, the inflamed nerves have to be removed, and at the same time the pain is removed, the tooth feels gone. At the same time, nutrients cannot penetrate deep into the teeth, and the teeth gradually become brittle, which is why it is recommended to protect the teeth after root canal treatment. Periodontal membrane&nbsp.&nbsp.&nbsp.&nbsp. In addition to dental pulp, periodontal membrane is also closely related to dental health. The periodontal ligament is a layer of soft tissue surrounding the tooth root in the picture. The periodontal ligament has one end opening in the mouth. If it is not cleaned properly, long-term inflammation will cause the periodontal ligament to become inflamed and destroyed, and gradually shrink toward the root. Macroscopically, it is inflammation and atrophy of gums. When the periodontal ligament is destroyed to a certain extent, the part of the tooth root that is wrapped is reduced. Just like a tree, the less it wraps in the mud, the weaker it becomes. Middle-aged and elderly people’s teeth are loose and fall off because of this reason. &nbsp.&nbsp.&nbsp.&nbsp. Above, we analyzed the causes and effects of dental diseases through different parts of the teeth. But we should know that the tooth and the surrounding periodontal ligament and alveolar bone are actually a whole, and problems in each part may affect each other. If small problems remain untreated, and multiple problems occur in multiple locations, the difficulty of treatment will increase linearly. Therefore, it is recommended that dental problems be discovered early and treated early.
