A dental extraction 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 are often recommended for impacted or problematic teeth.
Two types of extraction: Simple or SurgicalSimple extractions are performed on teeth that are visible in the mouth, usually under local anesthetic, and require only the use of instruments to elevate and/or grasp the visible portion of the tooth. Typically, when teeth are removed with forceps, slow, steady pressure is applied with controlled force. Surgical extractions involve the removal of teeth that cannot be easily accessed, either because they have broken under the gum line or because they have not erupted fully. Surgical extractions almost always require an incision.
Reasons for tooth extractionThe most common reason for extraction is tooth damage due to breakage or decay. There are additional reasons for tooth extraction:
- Severe tooth decay or infection
- Extra teeth which are blocking other teeth from coming in
- Severe gum disease
- In preparation for orthodontic treatment (braces)
- Teeth in the fracture line
- Fractured teeth
- Insufficient space for wisdom teeth (impacted third molars)
- Receiving radiation to the head and neck may require teeth extraction
