The best orthodontic stage is 1 1~ 18 years old. I had my teeth fixed when I was 14 years old. I have been doing it for more than two years. Because my teeth have been bad since I was a child, I have always paid more attention to oral care, so my teeth are not bad now. But when you were 48 years old, I felt that my whole tooth was not very good. Originally, the whole tooth pulled its position to the ideal position during the growing period of the tooth, which had an impact on the development of alveolar bone. Teeth are not very strong now. If you have a whole tooth, it will loosen easily when you get old. If you really want to make your teeth beautiful, you can go to the hospital to discuss the specific evaluation with your doctor.
