The face is round, the cheekbones and mandible are quite big, and the chin is short. I feel that the upper teeth are forward, the lower teeth are backward, and the tiger teeth are slightly protruding. After orthodontics, the face will change. You are an adult. Now orthodontics will not change the face shape, but simply move the position of the teeth. If you do it at the age of 12, you can change your face, but it's too late now. On the other hand, after orthodontics, people will become beautiful, but the face shape cannot be changed. You can have plastic surgery, melon seeds, and double eyelids.
