Kangbeijia dental experts will answer your questions. The optimal age for dental plastic surgery is between 12- 16. At this time, the teeth are not fully developed, and it is easier to change the shape of the teeth with braces. But it doesn't matter if you pass the best age of orthodontics. There is no age limit for orthodontics now. Even if you are old, you can correct it quickly with the right method and will not rebound. I hope my answer is helpful to you, and I wish you a happy life.
