Surgically removing wisdom teeth - the four permanent adult teeth located at the back corners of your mouth - is a common procedure. When wisdom teeth are impacted (unable to grow), causing pain, infection, or other dental problems, they need to be removed. Oral surgeons or dentists can remove wisdom teeth. Although impacted teeth may not currently cause problems, some dentists and oral surgeons recommend wisdom tooth extraction to prevent future problems. A wisdom tooth, or third molar, is the last permanent tooth to emerge in the mouth (erupt). Between the ages of 17 and 25, wisdom teeth tend to appear. Some people never develop wisdom teeth. Wisdom teeth may also erupt normally - like other molars - and cause no problems for others. Wisdom teeth that cannot erupt into the mouth or develop normally are called impacted wisdom teeth. Wisdom teeth that are impacted may not erupt at all or only partially erupt.
