Hello, there are two kinds of buckteeth, one is bony, that is to say, buckteeth are caused by maxillary protrusion, and it is best to correct them when changing teeth (children). After adulthood, alveolar bone is basically formed and slowly corrected. The other is protruding teeth with normal alveolar bone, which can be treated by correction. I suggest you take a lateral cephalogram and see what kind of situation you belong to before you know whether you can correct it. I hope I can help you.
