Medieval dentist extracting a tooth. London; c. 1360-75.

Historically, dental extractions have been used to treat a variety of illnesses. During the Middle Ages and throughout the 19th century, dentistry was not a profession in itself, and often dental procedures were performed by barbers or general physicians. Barbers usually limited their practice to extracting teeth, which not only resulted in the alleviation of pain, but often cured a variety of ailments linked to chronic tooth infection. Instruments used for dental extractions date back several centuries. In the 14th century, Guy de Chauliac invented the dental pelican[2] (resembling a pelican's beak) which was used up until the late 18th century. The pelican was replaced by the dental key[3] which, in turn, was replaced by modern forceps in the 20th century.^{[citation needed]} Image File history File links Download high resolution version (656x764, 125 KB) Summary Miniature on a initial D with a scene representing teeth (dentes).

The first book focused solely on dentistry was the "Artzney Buchlein" in 1530, and the first dental textbook written in English was called "Operator for the Teeth" by Charles Allen in 1685.^[10] It is said that the 17th century French physician Pierre Fauchard started dentistry science as we know it today, and he has been named "the father of modern dentistry". Among many of his developments were the extensive use of dental prosthesis, the introduction of dental fillings as a treatment for dental caries and the statement that sugar derivate acids such as tartaric acid are responsible for dental decay.

General dentistry

General practitioners of dentistry prevent, evaluate, diagnose, and treat diseases of the oral cavity and associated structures (e.g. the temporomandibular joint), as well as maintain the functionality and esthetics of the teeth and associated tissues and structures. They can prescribe medication , x-rays, and devices for home or in-office use. Many oral diseases (such as bilateral odontogenic keratocysts) and abnormalities (such as several unerupted teeth) can indicate systemic, neural, or other diseases. A general practitioner may refer patients to their physician or a specialist for further evaluation, or vice versa for treatment. The temporomandibular joint (From the Latin for too much jaw) is a diarthrodial joint that connects the condyle of the mandible (lower jaw) to the temporal bone at the side of a skull. ... Bilateralism is a term referring to trade or political relations between two states. ... An odontogenic keratocyst is a benign but locally aggressive developmental odontogenic cyst. ...

Contrary to popular belief, most dentists do not regularly clean teeth, and instead delegate this task to other oral health providers (e.g. dental hygienists). Most general practitioners of dentistry perform restorative, prosthetic, routine endodontic therapy, routine periodontal therapy, and simple exodontia, as well as performing examinations. General practitioners can choose which cases to treat, and which will be referred to a specialist for further care. Many general practitioners are comfortable treating more complex cases, as well as placing implants and surgically extracting third molars (wisdom teeth). All dentists must achieve a certain degree of skill in various disciplines in order to graduate from dental school and earn licensure. Many complex procedures are frequently referred to specialists.

Specialities

In addition to general dentistry, there are 9 recognized dental specialties in the US, Canada, and Australia. To become a specialist requires one to train in a residency or advanced graduate training program. Once residency is completed, the doctor is granted a certificate of specialty training. Many specialty programs have optional or required advanced degrees such as (MD/MBBS specific to Maxillofacial Surgery), MS, or PhD.
