When a tooth is broken or has significant decay, the ideal situation is to do a filling, root canal or other restorative procedure but occasionally this is not possible due to extensive damage to the tooth. Most extractions can be performed with the use of local anesthesia to numb the area. The tooth is then gently loosened and removed. Immediately after the extraction is competed, gauze is placed for the patient to bite down on to apply pressure to stop the bleeding.
