It's slightly hard to explain, but behind my top front teeth, there's a white flap I guess of gum tissue. It started out as a red bump after I had my braces tightened and had power chains put on to pull my teeth together. Now it's white and it like, peels back from the roof of my mouth. It's gross and irritating me. I'm in college and don't have the time nor the cash to go see my dentist, but it's genuinely worrying me. It's been there for about two weeks now, and I'm hoping it'll go away soon and on its own?
