Tooth extraction or tooth removal is performed when there is no other way to save a tooth from decay. Such is done either by simple extraction or surgical extraction in more complicated, severe cases when an old tooth blocks the growth of a new one. Anaesthesia is placed on the area to numb both the tooth and gums, making it easy to pull out the defective tooth with the use of forceps. In cases where a broken piece of tooth is submerged into the gums, surgical extraction is applied. When such is encountered, the best way is to see a dentist immediately so the condition does not worsen.
