Yes, there is no age limit for orthodontics. 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. The effect of correction on face shape is actually very small, unless it is a particularly serious buck tooth similar situation, don't worry too much. I suggest you go to the nearest hospital for a film examination. I hope I can help you.
