I am a 46 year old female with excellent dental health. About 18 months ago, I developed a small painless bump below the gum of a tooth I had crowned about 10 + years ago. It is rather flat when I wake up in the morning and enlarges with chewing throughout the day. About a week ago, I developed an identical bump on the outside gum of the same tooth--same scenario--small, painless, enlarges with chewing. I have seen both my dentist and an oral surgeon. They can find nothing wrong with the tooth by the bumps. They're more of an annoyance thn anything else. The outside bump is almost completely flat though now that I have developed this new bump. My gum health is excellent, no signs of gingivitis or bleeding. Any idea what's going on?
