A dental extraction is the removal of a tooth and is performed for a wide variety of reasons, including tooth decay. Fortunately, modern dentistry makes routine tooth extractions relatively comfortable, painless procedures.
Simple extractions are usually performed under local anesthetic and require only the use of instruments to elevate or grasp the visible portion of the tooth. Impacted or problematic wisdom teeth are routinely extracted, as are extractions of some permanent teeth to make space for orthodontic treatment. It the tooth cannot be easily accessed, either because it has broken under the gum line or because it has not fully erupted, it may require a surgical extraction.
