A tooth that is severely damaged may need to be removed. A surgeon who specializes in surgeries of the mouth (oral and maxillofacial surgeon) or your dentist can remove a tooth.
Before removing your tooth, your dentist will give you a local anesthetic to numb the area where the tooth will be removed. A stronger, general anesthetic may be used, especially if several or all of your teeth need to be removed. General anesthetic prevents pain in the whole body and will make you sleep through the procedure.Your dentist will probably recommend that you don't eat or drink after midnight on the night before surgery, so you are prepared for the anesthetic.
If you have any infections, surgery will usually be delayed until the infection has cleared up. Your doctor or dentist may have you take antibiotics to help heal the infection.
To remove a wisdom tooth, your dentist will open up the gum tissue over the tooth and take out any bone that is covering the tooth. He or she will separate the tissue connecting the tooth to the bone and then remove the tooth. Sometimes the dentist will cut the tooth into smaller pieces to make it easier to remove.
After the tooth is removed, you may need stitches. Some stitches dissolve over time and some have to be removed after a few days. Your dentist will tell you whether your stitches need to be removed. A folded cotton gauze pad placed over the wound will help stop the bleeding.
