Kitty, I have Periapical Cemental Dysplasia which is a benign tumor under a tooth. Maybe yours is similar, something like a cementoma that will just need to be watched. I was scared when they first told me I had a tumor, but not so much now that they've explained it and I did some reading on it.

Fingers crossed for you.

cementoma /ce·men·to·ma/ (semen-to´mah) any of a variety of benign cementum-producing tumors including cementoblastoma, cementifying fibroma, florid osseous dysplasia, and periapical cemental dysplasia, particularly the last.
