When do wisdom teeth need to be removed?

Q. When do wisdom teeth need to be removed?

A. Wisdom teeth, also called third molars, appear last in the mouth, usually in the late teens and early 20s. By that time, the mouth is often crowded and most can’t fully surface from the gums — they are said to be impacted. The surrounding area can easily become infected; many people with impacted wisdom teeth need to have them removed eventually.
