Wisdom teeth or third molars sometimes need to be extracted because they do not fit into the available space in the mouth. This can lead to crowding of teeth or gum infections. An OPG x-ray will reveal the relationship of the wisdom teeth to their surrounding structures. Sometimes a Cone Beam CT scan may be required to check proximity of wisdom teeth to an important nerve which runs in the mandible in a three dimensional image. Depending on their complexity wisdom teeth can be extracted at Smile Ville or the dentist may have to refer the patient to a specialist.
