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.
Reasons for tooth extraction
Extra teeth which are blocking other teeth from coming in.
Severe gum disease which may affect the supporting tissues and bone structures of teeth.
In preparation for orthodontic treatment (braces)
Teeth in the fracture line
Insufficient space for wisdom teeth (impacted third molars). Although many dentists remove asymptomatic impacted third molars, American as well as British Health Authorities recommended against this routine procedure, unless there are evidences for disease in the impacted tooth or the near environment. Receiving radiation to the head and neck may require extraction of teeth in the field of radiation.
Types of Dental Extraction
Extractions are often categorized as “simple” or “surgical”. Simple 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 the tooth is lifted using an elevator, and using dental forceps, rocked back and forth until the Periodontal ligament has been sufficiently broken and the supporting alveolar bone has been adequately widened to make the tooth loose enough to remove. 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. In a surgical extraction the doctor may elevate the soft tissues covering the tooth and bone and may also remove some of the overlying and/or surrounding bone tissue with a drill or osteotome. Frequently, the tooth may be split into multiple pieces to facilitate its removal.
When is tooth extraction necessary ?
extended inflammation, the surrounding tissues have to be protected, along with the other teeth incase the disease is not painful, but the broken, loosened tooth cannot be use for further tooth replacement fortunately, most teeth deemed irredeemable by the patient can still be saved.
Extracting wisdom teeth
Before extracting wisdom teeth, the doctor is informed of the condition of the tooth, and the surrounding anatomical parts by a panorama X-ray. A wisdom teeth operation may involve a flap establishment or the unification of the scar margins with stitches. Of course, this is completely painless. The benefit of the adequate size of sawing pin is that it can be removed without pain in the end, it almost slips out of its place.
