Dental Teeth Extraction

Dental Teeth Extraction

A dental teeth extraction, sometimes 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. Dental Teeth Extraction of impacted or problematic wisdom teeth are also routinely performed, as are extractions of some permanent teeth to make space for orthodontic treatment.

Historically, dental teeth extraction have been used to treat a variety of illnesses, as well as a method of torture to obtain forced confessions. Before the discovery of antibiotics, chronic tooth infections were often linked to a variety of health problems, and therefore removal of a diseased tooth was a common treatment for various medical conditions. Instruments used for dental extractions date back several centuries. In the 14th century, Guy de Chauliac invented the dental pelican, which was used through the late 18th century.

The pelican was replaced by the dental key which, in turn, was replaced by modern forceps in the 20th century. As dental extractions can vary tremendously in difficulty, depending on the patient and the tooth, a wide variety of instruments exist to address specific situations.

Reasons for tooth extraction

The most common reason for extracting a tooth is tooth damage due to breakage or decay. Some other possible reasons for tooth extraction are as follows:

– Extra teeth which are blocking other teeth from coming in.
– Severe gum disease which may affect the supporting tissues and bone structures of teeth.
– Severe tooth decay or infection.
– In preparation for orthodontic treatment (braces)
– Insufficient space for wisdom teeth (impacted wisdom teeth).
– Receiving radiation to the head and neck may require extraction of teeth in the field of radiation.

Types of dental teeth extraction

An extracted 3rd molar that was horizontally impacted. Extractions are often categorised as “simple” or “surgical”.

Simple extractions are performed on teeth that are visible in the mouth, usually under local anaesthetic, 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 subsequently 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.

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. 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.
