Wisdom tooth extraction is a surgical procedure to remove one or more wisdom teeth - the four permanent adult teeth located at the back corners of your mouth on the top and bottom.
Wisdom teeth are the last of your teeth to come in, or erupt, through the gums.
How it's Performed
Wisdom tooth removal can be carried out by a dentist or a specialist surgeon working in a hospital. If your dentist recommends removing your wisdom teeth, they'll take an X-ray of your mouth to help them determine who should carry out the procedure.
Any charges and payment methods should be discussed before the procedure begins.
Anaesthesia
Before having your wisdom teeth removed, you'll be given an injection of local anaesthetic to numb the tooth and surrounding area. If you're particularly anxious about the procedure, your dentist or surgeon may give you a sedative to help you relax. This usually involves an injection into your arm.
General anaesthetic is rarely necessary. When it's needed, your wisdom tooth will be removed in hospital, although you should still be able to go home on the same day as the procedure.
Removing the wisdom tooth
If the tooth hasn't come through the gum, a small cut (incision) will be made in the gum to access it. A small piece of the bone covering the tooth may also need to be removed.
The tooth may be cut into smaller parts to make it easier to remove through the opening. There's less need to make an incision if the tooth has broken through the gum.
You'll feel some pressure just before the tooth is removed. This is because your dentist or oral surgeon needs to widen the tooth socket by rocking the tooth back and forth before taking it out.
After surgery
If an incision has been made, dissolving stitches are used to seal the gum. Your dentist will tell you how long the stitches take to dissolve (usually 7 to 10 days).
Your dentist may place gauze over the site of the extraction and ask you to keep pressure on it by biting your jaws together for up to an hour. This is to allow a blood clot to form in the empty tooth socket. Blood clots are part of the healing process, so try not to dislodge them.
