"Students are the main force of orthodontics, and the annual outpatient visits account for more than half of the summer vacation. But because many people don't understand, most children who come to orthodontics miss the best period. " According to the introduction of early education experts, 12 years old was chosen to correct the teeth because at this time, the whole dental arch of the child was basically developed, the deciduous teeth were basically replaced, the permanent teeth were basically full, the roots of the permanent teeth gradually developed, and the occlusal relationship between the upper and lower teeth was also adjusted. Dentists can make a clear diagnosis of the types of malocclusion and take corresponding corrective measures.

At the same time, 12-year-old children have good biological response to external stimuli, rapid bone remodeling, high plasticity, vigorous tissue metabolism, short treatment cycle, good effect and easy to maintain the effect after correction.

However, some dentofacial deformities, such as "covering the sky" and biting lips, need to be treated at the age of 3~5; Some dentofacial deformities should be corrected when the permanent teeth of 8~ 10 years old have begun to erupt.

Orthodontic treatment is mainly to wear orthodontic appliances, which can be divided into movable appliances and fixed appliances according to the residence time of appliances in the mouth. The two types of appliances have their own indications, and orthodontists will choose according to the age of patients, the nature and severity of dentofacial deformities.

Experts remind that after wearing braces, teeth will feel sore and weak because they don't adapt to the traction of braces, so you need to eat soft food for the first three days to avoid increasing pain, such as soft rice and porridge. After a week of basic adaptation, you can eat normally, but you can't eat hard and sticky food, such as eating nuts such as walnuts and gnawing bones, during the corrective treatment of 1~2 years.

In the process of orthodontic treatment, there are different tooth movement schemes at different stages, which require regular follow-up, and the doctor will adjust the appliance according to the movement of a certain tooth. The fixed appliance was followed up every 4~6 weeks, and the movable appliance was followed up every 2~3 weeks.
