One of the most common oral surgery procedures is the removal of wisdom teeth. Wisdom teeth may be extracted due to existing discomfort, decay or to prevent common problems that may arise in the future.
When wisdom teeth begin to erupt, a number of problems may occur. If the jaw is not large enough, the teeth may become impacted and unable to break through the surface of the gums. Sometimes, wisdom teeth partially erupt through the gums. A flap of gum tissue grows over them causing food and germs to get trapped under the flap. This may result in red, swollen, and painful gums, which can be signs of infection. More serious problems can develop from impacted teeth, such as infection, damage to neighboring teeth and bone or cyst formation.
Wisdom teeth and general extractions can be done under local anaesthesia, IV sedation or general anaesthesia. Before removing a tooth, local anaesthesia is given to numb the area where the tooth will be removed. IV sedation may be used, especially if several or all of your wisdom teeth will be removed at the same time.
