It is not too late. Although you missed the best correction age at this age, you can still correct it. Although the best age for orthodontics is 9- 13-year-old teenagers, in theory, as long as the teeth are healthy, orthodontics can be done regardless of age, but the correction time will be slightly longer than that of minors. Adult orthodontics generally takes about one and a half to two years, or even longer, depending on the individual's tooth reduction and alveolar bone absorption. I hope I can help you.
