my wisdom teeth came in with no problems. A year ago a peice of one wisdom tooth brook off, it continues to break away little by little. I don't see any signs of a cavity and have no pain. Should i be concerned?
I'd certainly be concerned. Absence of pain is not a reliable criteria to base your decision to see a dentist. Listen to yourself. You've observed your tooth breaking away bit by bit. This is clearly not what normal teeth undergo.
