The third molar is the last tooth to develop and erupt into the mouth, which usually occurs around the age of 18, give or take a few years. This can be accompanied by discomfort which may come and go in cases where there is insufficient room for the teeth to erupt, often leading to small gum infections in the area. Crowding of teeth may also be a consequence of leaving the teeth in place, and many orthodontists request their removal to facilitate the movement of the molars. Malpositioned third molars may also lead to cavities on the tooth just in front of them, and also increase the risk of developing periodontal gum disease. Most wisdom teeth are removed prior to developing symptoms when there will not be enough room in the mouth for them to fully erupt. The ideal time to remove these wisdom teeth is before the roots have fully developed. This leaves more room between the tooth roots and the nerve that gives feeling to the lower lip, generally making it a safer time to remove them with fewer risks of complications. People develop their teeth at different rates, but most people’s wisdom teeth are at the ideal stage of development for removal between 15-18 years old.
