Description

Tooth extraction can be performed with local anesthesia if the tooth is exposed and appears to be easily removable in one piece. The dentist or oral surgeon uses an instrument called an elevator to luxate, or loosen, the tooth; widen the space in the...

underlying bone; and break the tiny elastic fibers that attach the tooth to the bone. Once the tooth is dislocated from the bone, it can be lifted and removed with forceps.

If the extraction is likely to be difficult, a general dentist may refer the patient to an oral surgeon. Oral surgeons are specialists who are trained to administer nitrous oxide (laughing gas), an intravenous sedative, or a general anesthetic to relieve pain. Extracting an impacted tooth or a tooth with curved roots typically requires cutting through gum tissue to expose the tooth. It may also require removing portions of bone to free the tooth. Some teeth must be cut and removed in sections. The extraction site may or may not require one or more stitches (sutures) to close the incision.

Dental implants provide an extremely secure way of attaching an artificial tooth to the jaw itself.

A dental surgeon uses special forceps to pull out a tooth (A). In its place, a blood clot forms (B), which becomes new bone with gum tissue over the top (C). If the blood clot does not form or falls out, a dry socket occurs (D). No new bone forms, and the nerves are exposed, causing pain. (Illustration by GGS Inc.)

Other Information

A dental extraction (also referred to as exodontia) is the removal of a tooth from the mouth. Extractions are performed for a wide variety of reasons, including tooth decay that has destroyed enough tooth structure to prevent restoration. Extractions of impacted or problematic wisdom teeth are routinely performed, as are extractions of some permanent teeth to make space for orthodontic treatment.
