Your dentist or surgeon will give you a local anesthetic to numb the gums and prevent any pain during the procedure. If you are removing all of your wisdom teeth, they may use a general anesthetic instead - you may be required to avoid eating or drinking after midnight on the night before surgery so you can be prepared for the anesthetic.
When the surgeon is ready to remove your wisdom tooth, they will make a small incision on any gum tissue over the tooth. Sometimes there is still bone covering the wisdom teeth, which will need to be removed. The tooth is then extracted as a whole, or cut into small pieces and extracted. Once you have your wisdom teeth removed, you may need small, non-invasive stitches over the cut tissue.
The recovery time of wisdom tooth extraction is only a few days in most cases, and the healing process can be sped up by brushing your teeth carefully, rinsing your mouth with warm salt water on a daily basis and avoiding smoking or drinking with straws as this could cause the cut to open and potentially tear stitches.
