The four permanent adult teeth known as wisdom teeth are placed at the top and bottom rear corners of your mouth. A wisdom tooth extraction is a surgical operation to remove one or more of these teeth. You’ll probably need to have a wisdom teeth removed if it is impacted, or if it is causing you pain, an infection, or other dental issues. An oral surgeon or a dentist can remove a wisdom tooth. Even if impacted teeth aren’t currently causing issues, some dentists and oral surgeons advise wisdom tooth evacuation to avoid potential future issues.
