i had buck teeth as a kid and had braces to correct it. now though, i feel my front two teeth still are visible when i relax my mouth. i've seen an orthodontist and he says the front teeth can't be pulled back any further. Is my upper lip the problem? it makes a triangular shape. it doesn't sit in a relatively straight line. can my upper lip be pulled down or altered so it covers my front teeth. this problem also means i strain to close my two lips together.
