I have a large lump in the top of my mouth, and some of my teeth are 3rds and 4ths, I also had polops removed from my ccolon that were not cancer. I don't know of any genetic problems in either side of my family and we are all close so I don't see this being Garners which I only heard about online. What else could this be? The roof of my mouth bothers my and it hurts to get teeth at 38. They only come in when one is removed like the one I'm getting now was pulled 6 years ago.
