...I know you must be frantic to think you might have a recurrence, and I know that you will get it checked out immediately, if not sooner, but to be honest, it sounds like a tora --plural, tori? (you dentists out there....is that the right name?) I have many of these bony bumps on the lingual sides of my mandibles. My mother had them also and was told that she had better take good care of her teeth, because she would have a terrible time being fitted for dentures!

Take a deep breath and go get it checked. Let me know if I am right.
