Orthodontic methods generally include traditional metal bracket appliances, ceramic bracket appliances, invisible bracket-free appliances and lingual appliances. At your age, you can have orthodontics. 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 time for orthodontics will be slightly longer than that of minors. Adult orthodontics generally takes about one and a half to two years, and may be longer. I hope I can help you.
