Wisdom teeth are the last of your teeth to come in, or erupt, through the gums. Sometimes a wisdom tooth becomes impacted if it does not have room to grow, or stuck below the surface of your gums, and grows at an odd angle, possibly causing complications.

Wisdom tooth extraction is a surgical procedure which is done to avoid dental complications.

Wisdom tooth extraction is sometimes recommended even if impacted teeth aren't causing problems, as a preventive measure against potential future problems.

A wisdom tooth extraction is almost always performed as an outpatient procedure. This means that you go home the same day.

You'll receive instructions from the hospital or dental clinic staff on what to do before the surgery and the day of your scheduled surgery. 

Post-surgical instructions are given by the dental surgeon after the extraction is done.
