Wisdom tooth
extraction is a surgical procedure to remove one or more wisdom teeth — the
four permanent adult teeth located at the back corners of your mouth on the top
and bottom.
If a wisdom tooth
doesn't have room to grow (impacted wisdom tooth), resulting in pain, infection
or other dental problems, you'll likely need to have it pulled. Wisdom tooth
extraction may be done by a dentist or an oral surgeon.

To prevent potential
future problems, some dentists and oral surgeons recommend wisdom tooth
extraction even if impacted teeth aren't currently causing problems
