I got my wisdom teeth removed in august of 2015 and now, it feels like teeth are growing in in the spots where extracted. what are they? normal?

Healing: Not possible for teeth to be growing in those spots. However your tissue may be healing over and thickening as is normal. Your Dentist can take a look to see if all is within normal range.

Not normal: Lots of possibilities. To be diagnosed, however, you need to be physically examined and x-rayed. Please return to the Surgeon who removed your wisdom teeth for reevaluation.
