Recently the winter vacation is here, many parents consult the orthodontic problems, the most asked is how old is the right age to orthodontic. We would like to talk to you about the timing of orthodontic treatment. Generally speaking, the best time for orthodontic treatment is divided into several stages according to different problems. 1, that is, after the baby teeth are all grown, then some of the problems of the baby teeth should be corrected at an early stage, such as anticlinal and so on. The age of treatment is about 3-6 years old, at this time the children’s permanent teeth have not yet erupted, the roots of the milk teeth have not yet absorbed, more stable, you can wear the oral activity of the braces for simple orthodontic treatment, the course of treatment is about half a year or so. Early treatment is very beneficial to the normal development of children’s jaw and face. 2. Tooth replacement stage. About 7 to 11 years old, when the newborn permanent teeth begin to erupt, the teeth grow quickly, the bite is unstable, is the most common period of malocclusion. The main reason is the early loss of milk teeth, resulting in a reduction in the length of the dental arch, which in turn causes the teeth to be misaligned, this kind of children should do gap keeper; early loss of milk teeth makes the gap closed, resulting in the permanent teeth do not have enough space for eruption of malocclusion caused by malocclusion, through the orthodontic appliances to restore the gap; malodontia caused by bad oral habits, in overcoming, changing the bad habits at the same time, according to the different circumstances, different degrees can be from light to heavy, respectively Adopting movable or fixed orthodontic appliances; there are also some jaw development problems, such as small chin, ground bun, etc., which should also be intervened at this stage to avoid jaw deformity to develop in a more serious direction. 3.After all the teeth have been replaced or when only individual teeth remain to be replaced. Generally around 12-18 years old, this is the best time for orthodontic treatment as mentioned by most of our parents. At this time, the diagnosis of malocclusion is clearer, and orthodontic treatment during this adolescent growth period is faster and more stable. So, is it possible to miss these optimal times for orthodontic treatment? The answer is yes. If you have missed the above orthodontic period, you can still undergo adult orthodontics after the age of 18 to establish a good occlusal relationship and release the crowded and misaligned teeth, in order to prevent or treat periodontal disease and caries. At this time, orthodontics can restore the functions of mastication, speech, temporomandibular joints, and improve the aesthetics of the face by adjusting the axial direction of the teeth for implantation or restoration. For serious deformities, combined orthodontic-orthognathic treatment can be performed with very obvious results. Therefore, determining the best time for orthodontic treatment is not absolute; orthodontic specialists will depend on the different types of malocclusion and the growth and development of the individual. However, for many patients with facial deformities caused by teeth, it is still necessary to treat them as early as possible and in time in order to receive twice the result with half the effort.
