Wisdom teeth are the third molars. Normally erupted wisdom teeth occlude properly with their corresponding opposing teeth in the upper or lower dental arch. They are located within the same dental arch curve as the second molars, and the crowns are not covered by any gingival tissue. In clinical situations, normally erupted wisdom teeth are rare, while impacted wisdom teeth are common. Malpositioned wisdom teeth could be defined as impacted wisdom teeth.
