It's never too late to straighten your teeth, it will only get harder and harder. Here is a correction. Correcting teeth is not the best time for children to correct their teeth after changing their teeth.
① defoliation period (4~5 years old)
This period is mainly suitable for malocclusion of deciduous teeth, that is, to cover the day.
② Tooth-changing stage (girls: 8~ 10 years old, boys: 9~ 12 years old)
At this stage, if you find that your child has bad habits such as biting his lips, sticking out his tongue and stretching his chin forward, you can go to the dentist.
③ permanent tooth stage (female: 1 1~ 14 years old, male: 13~ 15 years old)
Children's bones are basically shaped, and common dental problems can be well corrected at this stage.
Adults can correct their teeth as long as their periodontal health is good, but the correction time will be longer.
