Hello, there is an optimal plastic surgery period for orthodontic treatment. But there is no age limit. It is best to undergo dental plastic surgery when boys are around twelve years old and girls are around eleven years old, because at this time the deciduous teeth have just been replaced and the jaws still have the potential to develop, which is conducive to better plastic surgery results. After dental plastic surgery It can also grow normally. If oral problems occur, it is better to diagnose and treat them in time, because early diagnosis and treatment can better carry out dental plastic surgery, which will take less time and cost less.
