Wisdom teeth are the last molars, or "third molars", that develop on each side of the jaws. Wisdom teeth usually emerge in the back of the mouth between the ages of 16-20.
Wisdom teeth are a valuable asset to the mouth when they are healthy and properly positioned. Often, however, problems develop that require their removal. Wisdom teeth may grow sideways, emerge only part way through the gum or remain trapped beneath the gum and bone. Their movement may lead to painful headaches or jaw achiness. If partially or fully erupted they are prone to decay due to how far back in the jaw they are located.
An erupted wisdom tooth extraction is a relatively routine procedure. The dentist will numb the area in your mouth with a local anesthetic for the extraction. If you require or would like IV sedation, so you are asleep during the procedure, an oral surgeon is indicated for the extraction.
After the tooth (or teeth) is removed, you may be asked to bite down softly on a piece of gauze for 30 to 45 minutes after you leave the office. This helps reduce bleeding and aids clot formation. Some pain and swelling may occur, but it will normally go away after a few days; however, you should call your dentist if you have prolonged or severe pain, swelling, bleeding or fever.
