A tooth extraction, or exodontia, is the removal of a tooth. Reasons for a tooth extraction include decayed or broken teeth. They may also be removed to make room for other teeth for an orthodontia treatment.
There are two main types of tooth extractions: simple extractions and surgical extractions. Simple extractions are performed on visible teeth in the mouth under local anesthesia. The tooth is loosened from its socket and then removed with dental forceps.
Surgical extraction is a more complicated procedure done on teeth that have broken under the gum line or have not fully erupted and is generally done under general anesthesia.
Exposure of tooth buried in gums is carried out to facilitate its eruption in mouth under local anesthetic. Following small surgical procedure of exposure, a gold chain is attached to tooth so it can be brought into position by orthodontic appliance.
