About 3 days ago I noticed a small bump between my cheek and gum (at the base), just enough to be annoying but it didn't hurt. Now days later it's swollen and red and soft, fleshy. I swabbed it often with hydrogen peroxide, and now am using Listerine because of the alcohol content. The spot is small and has a small white line on it, like a coating, but in my head it feels large. It's very tender. It doesn't seem like a cyst though, and it's at the base of my gum where a tooth used to be but was pulled. This tooth had a root canal but got absessed years ago so my dentist pulled the tooth. It has never bothered me since.

Any ideas?
