A wisdom tooth or third molar is one of the three molars per quadrant of the human dentition. It is the most posterior of the three. The age at which wisdom teeth come through (erupt) is variable, but generally occurs between late teens and early twenties.
Wisdom teeth have long been identified as a source of problems and continue to be the most commonly impacted teeth in the human mouth.

Treatment of an erupted wisdom tooth is, if impacted, treatment can be restoration, local treatment to the infected tissue overlying the impaction, extraction or coronectomy.
