Q. Im 17 and I have a very prodruding jaw and can’t even smile because im so self concious, my face looks flat and my chin sticks out. I’ve tried to convince myself its not noticable but i have had a couple of people comment on it. I think i may have a very slight underbite but i can just make my top teeth go over the bottom one. Is it possible for me to get jaw surgery to correct it? It not purely costmetic because i do get an aching in my jaw as well. Would i be able to get this on the NHS? Or if i would have to pay how much would it cost?
