Wisdom teeth are often best removed before the age of twenty years as root formation may not yet be completed. If the wisdom teeth are erupted, the tooth (or teeth) will normally be removed with local anaesthetic. After surgery, you may be asked to bite down softly on a piece of gauze for 30 minutes after you leave the surgery, to limit any bleeding that may occur.
If the wisdom teeth are impacted and embedded in the bone, the oral surgeon will put an incision into the gums and remove the tooth or teeth in sections in order to minimise the amount of bone being removed. Some pain and swelling may occur, but it will normally go away after a few days; however, you should call your dentist or oral surgeon if you have prolonged or severe pain, swelling, bleeding or fever.
After surgery, swelling and tenderness in the face and neck are common, as is bruising. Ice packs and pain medications prescribed by the dentist or oral surgeon will help, but if you have any questions or are concerned about what you are experiencing, contact your practitioner.
