Experts from Shanghai Stomatological General Hospital said that the sooner the ground coverage days are corrected, the better. So when is the best time for children to be corrected?

1. Occlusal period of deciduous teeth: When malocclusion or malocclusion (partial occlusion) of deciduous teeth occurs, it should be corrected as soon as possible. The best age of treatment is 4 ~ 6 years old, and the course of treatment is about 6 months.

2. Mixed (replacement) occlusal period: It begins at the age of 6- 12, when new permanent teeth begin to erupt, teeth grow rapidly, and occlusion is unstable, which is the frequent period of tooth deformity.

3. Occlusal period of permanent teeth: all deciduous teeth have been replaced, and the second and third big teeth erupt into another rapid growth period, generally around 12 ~ 18 years old. At this time, the diagnosis of tooth deformity is clear, and the correction speed is fast and the correction effect is stable in the rapid growth period.
