It is understood that the healthiest way to arrange teeth is: the upper and lower teeth are neat; The coverage of anterior teeth was normal (upper teeth under the cover1-3 mm); The occlusion of 2mm posterior teeth (incisors and molars) of the upper and lower teeth combined jaw is a cusp-fossa relationship. Remind parents and friends to pay attention to their children's teeth and take them to the hospital for an orthodontic examination every six months, so as to find problems at any time and treat them in time.

The best period of orthodontics in children

Optimum period 1: deciduous period

According to the oral experts of China Dental Protection Network, the occurrence of irregular arrangement or malocclusion of deciduous teeth, occlusion of local teeth and so on should be corrected as soon as possible. The treatment age is about 3 ~ 6 years old. At this time, the child's permanent teeth have not erupted, and the roots of deciduous teeth have not been absorbed and are relatively stable. It can be corrected by wearing oral appliance, and the course of treatment is about 6 months. Early treatment is very important for the normal development of children's maxillofacial region. If it is not corrected in time, it may aggravate the deformity in this rapid growth period.

The best period 2: mixed dental period

About 8 ~ 10 years old, at this time, new permanent teeth begin to erupt, teeth grow rapidly and occlusion is unstable, which is the frequent period of tooth deformity. The main reason is that deciduous teeth fall off prematurely, which leads to the reduction of dental arch length, which in turn leads to the inability to arrange teeth. Such children should be regarded as gap holders. The deciduous teeth fall off prematurely and close the gap, which leads to insufficient eruption space of permanent teeth and tooth deformity. The gap should be repaired with orthodontic appliances. Tooth deformities caused by bad oral habits or hobbies can be corrected by movable or fixed appliances according to different situations and degrees, and even by external plastic forces.

The best period 3: permanent tooth period

Dental experts from China Dental Protection Network said that all primary teeth have been replaced, and when the second and third big teeth erupt, it will be a rapid growth period, generally around 12 ~ 18 years old. At this time, the diagnosis of tooth deformity is relatively clear, and the correction speed is fast and the correction effect is stable in this rapid growth period.
