I did it at a dentist near my house when I was in high school, and Im satisfied!! The purpose of treatment was stronger than that of cosmetic purpose. The upper teeth were all covered with the lower teeth, so it was invisible. It turned out that the upper jaw was straight, but the lower jaw was not. So, the upper jaw was inserted and the lower jaw was moved forward. My chin was slim and it became thicker after correction, but I am satisfied because my lower teeth do not scratch the roof of my mouth.
