I thought that my teeth were not properly aligned and my mouth protruded a little, so I started straightening my teeth right after I was discharged from the army. During the consultation process, I found out that I have a slightly wrinkled chin, and I decided not to extract the chin because it might make my chin stand out when I put it in my mouth. I was also a little reluctant to pull out raw teeth. There is no dramatic aesthetic change after orthodontic treatment, but the right molar could not chew while lying down. I am a person who seeks , but it is slightly uncomfortable. In conclusion, what I feel is that if a person with severe esthetic protrusion receives orthodontic treatment, it will be really dramatic (I regret that I should have thinned it)..
