I have had orthodontic treatment for 4 years. There was a slight protrusion, but nothing serious. The reason for the correction was that I was concerned that the front teeth were rabbit teeth and the gums were visible. After an examination later, I found out that I had an overbite. So, after the hard orthodontic treatment, I was not happy with the result. I didn't know what the problem was at the time, but I was watching YouTube a few months ago and saw that one of the side effects of orthognathic surgery was hapjuk (grandmother). .
