Dental Extraction or tooth extraction as it is commonly referred to, is the removal of teeth/tooth from the oral cavity. The most common reason for tooth extraction is tooth damaged beyond repair due to decay or trauma. Other reasons include infection from tooth decay, a crowded mouth to make space for braces, periodontal (gum) disease and risk of infection during radiation or chemotherapy. Removal of wisdom tooth or third molar is yet another popular reason for tooth extraction. Tooth extractions are relatively simple process and are performed under the impact of local anesthesia. Some teeth are more difficult to remove because they have broken under the gum line or not erupted fully. Such teeth require surgical extraction. Healing usually takes one to two weeks. It is recommended to replace missing teeth with an implant or fixed bridge or dentures to avoid the shifting of remaining teeth which might pose problems in biting or chewing.
