Wisdom Tooth Coronectomy
A Wisdom Tooth Coronectomy involves removing the crown of the lower wisdom tooth, leaving the roots in the gum. Common reasons to remove only the wisdom tooth crown include: Pericoronitis or tooth decay to the wisdom tooth or the adjacent tooth.
The roots of most lower wisdom teeth are close to a nerve in the lower jaw called the inferior alveolar nerve. The reason to leave the roots behind is to minimise complications to this nerve. However there is a risk that the remaining roots become infected and have to be removed in a second treatment.
During your appointment a local anaesthetic injection will be placed into the gum next to the wisdom tooth being treated. When the gum and tooth are completely numb a small cut is made in the gum and a surgical drill is used to remove the wisdom tooth crown. A few small stitches are placed into the gum to help healing.
