A: Not all problems related to third molars are painful or visible. Damage can occur without your being aware of it. As wisdom teeth grow, their roots become longer, the teeth become more difficult to remove and complications become more likely. In addition, impacted wisdom teeth are more likely to cause problems as patients age. No one can predict when third molar complications will occur, but when they do, the circumstances can be much more painful and the teeth more difficult to treat. It is estimated that about 85% of third molars will eventually need to be removed.
