Impacted wisdom teeth Impacted wisdom teeth (or impacted third molars) are wisdom teeth which do not fully erupt into the mouth because of blockage from other teeth (impaction). If the wisdom teeth do not have an open connection to the mouth, pain can develop with the onset of inflammation or infection or damage to the adjacent teeth. Wisdom teeth likely become impacted because of a mismatch between the size of the teeth and the size of the jaw. Impacted wisdom teeth are classified by their direction of impaction, their depth compared to the biting surface of adjacent teeth and the amount of the tooth's crown that extends through gum tissue or bone.
