Hello! Adults can have plastic surgery as long as their teeth are not loose and there is no periodontitis. No problem. Everyone has a love of beauty, so we should correct it while we are young. The older you get, the harder it is. The disadvantage of adult orthodontics is that it is easy to cause tooth loosening, but it can be avoided. The light force is used in the orthodontic process. I suggest you go to a regular dentist, and the quality is guaranteed.
