Hello, orthodontics and plastic surgery are the best. But there is no age limit. Boys 12 years old, girls 1 1 year old, it is best to have dental plastic surgery, because the deciduous teeth have just been replaced, and the jawbone still has development potential, which is conducive to better plastic surgery and normal growth after dental plastic surgery. If you have oral problems, you'd better make diagnosis and treatment in time, because early diagnosis and treatment can better carry out dental age plastic surgery, with less time and less cost.
