Wisdom teeth account for 98% of all impactions. They are the last teeth of permanent series to erupt. Mandibular third molar is the most commonly impacted tooth. It is in general agreement that symptomatic third molar that will not erupt normally should be removed. The retention of impacted third molar gives too many complications such as pain, swelling, pericoronitis, caries, neuralgias, pressure resorption of adjacent tooth and even may be a source of cyst and tumor formation. The treatment of choice for symptomatic impacted mandibular third molar remains its surgical removal.
