If a person has uneven teeth, it not only affects the aesthetics, but also affects the function of pronunciation and chewing, and has a certain negative impact on the psychology, so it should be corrected. At present, orthodontic medicine in China has developed greatly, but because it is not very common to carry out this work, so not everyone with uneven teeth can be corrected. Generally speaking, the treatment effect is better for people who are young, healthy and have good oral conditions. If there is a serious dental disease in the mouth at the same time, the treatment results are most likely not good. Before undergoing orthodontic treatment, the patient’s teeth should be thoroughly treated, such as extraction of all diseased teeth that cannot be treated or should not be retained (such as multiple teeth and buried teeth), before orthodontic treatment can be performed. The key to treating oral malformations is early detection and early treatment. Infants and children should go to the hospital dentistry department for an examination after the milk teeth come out at the age of two and a half, and do a good job of oral health care for children under the guidance of doctors to correct bad habits such as finger-sucking and hanging objects. Children should have an oral examination once a year if conditions allow. Commonly, milk tooth eruption should be treated at the age of about 4 years old, tooth replacement should be at the age of 7-12 years old, while the best period for orthodontic treatment of permanent teeth is 12-14 years old. Orthodontics is the process of rearranging teeth and restoring oral function and normal form while keeping the original tooth form unchanged, not just for aesthetic purposes, but also as a process of biological alteration of the oral skeleton, a process that generally takes about two years. This process usually takes about two years. It should not affect study and work. If the child only has misaligned teeth, it can wait until the early stage of permanent teeth (after tooth replacement) treatment, if the misalignment is accompanied by receding lower jaw or underdeveloped upper jaw, then it should be treated immediately. Orthodontics is the process of realigning teeth and restoring oral function and normal form while keeping the original tooth form unchanged, not just for aesthetic purposes, but as a process of biological alteration of the oral skeleton, a process that generally takes about two years. Before orthodontic treatment, plaster casts are made to be used as a reference for future treatment results. Depending on the condition of the disease, the doctor designs different kinds of braces. There are still quite a few types of aligner technology, including: movable aligner technology, square wire arch technology, Begg technology, TN technology, Alexander technology and now a more advanced MBT orthodontic technology. The aligners are worn in the mouth and are usually checked and treated every two to three weeks. It depends on the specific case to decide how long the aligners should be worn. Orthodontic treatment is generally better before the age of fifteen, because here during the development of the jaws, the treatment effect is more rapid and ideal, the older the treatment effect, the worse. At present, China has a number of medical institutions with orthodontic treatment settings, but not many doctors have been formally studied, there are many orthodontic treatment of teeth can not be treated in a timely manner. Therefore, we should promote the knowledge of prevention and protection of teeth, remove the bad habits that are harmful to oral development, and prevent the occurrence of dental irregularities early. Treated teeth do not affect eating. Adults can also get orthodontic treatment nowadays, which usually takes about 2 years. They can wear ceramic clear locking slot, which is similar to the color of teeth and will not be obvious, but it is more expensive. Orthodontic treatment is painless, except for about 2 days of discomfort after each follow-up appointment with added force, without any analgesics. Generally, children need to wait until all of their baby teeth have been replaced (about 11-13 years old) before orthodontic treatment. However, there are some cases that need to be corrected as early as possible, such as retrusion (diastema), severe deep overlap, deep overlap, bad oral habits, multiple teeth, etc., because these conditions can make the malocclusion more and more severe and difficult to treat. It is recommended that you take your child to the hospital for an examination and consultation in order to determine the timing of orthodontic treatment. Crowded teeth are due to insufficient amount of jawbone to line up the normal number of teeth, if there is not enough space in the teeth is to reduce the number of extractions after orthodontic treatment. After the teeth are extracted and orthodontically lined up, the extra gap will be closed and there is no need to worry. However, there is one thing: the doctor who treats you must be a professional who has undergone formal study. If your doctor recommends that you extract your teeth and you don’t, the possible adverse effects are: 1, the reduction of chewing efficiency, affecting your full absorption of nutrients in food, resulting in malnutrition, serious enough? I don’t know if your body shape is thin, 2, eating often will be stuffed teeth, very painful, such as: eat beef, celery and other fiber-rich food; 3, is not conducive to teeth and periodontal self-cleaning role of food debris, over time will cause periodontal disease, and finally cause teeth loosening or even fall off. There are many reasons for anti-jaw, such as heredity, bad habits, tooth replacement disorder and so on. If the jaw is functional, it should be corrected during the third growth spurt or pre-peak period. The peak period for girls is right at 10 – 12 years old, and if you miss it, you will have to do masking treatment. Even if it is not a functional antimandibular, it is important to correct the antimandibular as soon as possible to facilitate normal jaw development. Some doctors say no treatment is necessary, that may be because he or she has not yet applied functional orthodontic treatment. It is recommended to go to a regular hospital for treatment! Pseudo-transjugation caused by incorrect breastfeeding. It is important to adopt the correct way of breastfeeding, not to let the child lie down to eat milk, and to feed the child in a sitting or standing position with the pacifier placed slightly down in front of the mouth. It is best not to let the child suck the pacifier empty and not to advocate horizontal breastfeeding by the mother. This is because all of the above poor feeding practices can cause impairment to the development of the baby’s jaw and facial bones. This is the most common factor. It is also important to observe whether your baby has the habit of biting the upper lip, if so, it should be eliminated as soon as possible. Children younger than two years old do not need special treatment, as long as the bad practice is corrected, soon your baby’s “gumbo” will be gone.
