Well I've recieved dental treatment and I've weared braces for like 4 years until some years ago, but I couldn't help to notice the tendency my lips have not to close properly when I relax my mouth. I guessed braces should have fixed this but I still feel like my frontal teeth tend to protude towards outside and my upper teeth take up a lot of space inside my mouth; I feel they are really big. Thoughts on this? Is this normal or expected even after years with braces?
