Hi everyone. I am new to the forum. I just have a question. I've read that mouth-breathing causing an unattractive facial structure, I hate to admit it, but I think it's true. Where my family has very defined attract looks, I do not. I have a very sunken chin. It seems to slightly block my airway as well. I want to have lower jaw advancement, but it could be a problem because I have had braces are almost perfectly aligned my teeth. I have thought about it, and I do think this is something I want to do for cosmetic and functional reasons. Can I advance my jaw and bring my teeth back with braces?
