When it becomes necessary to remove a diseased, damaged, or malpositioned tooth, the procedure is handled as a form of minor surgery, usually with the administration of local anesthetic to the nerves supplying the tooth area. However, there is no standard routine for extractions of a tooth, because of the numerous individual variations associated with each case. The dentist usually has a medical history of the patient available, showing such information as allergies to drugs, and medications used by the patient that might react with those employed in periodontal surgery.
Because the mouth contains many millions of bacteria, all possible precautions are taken to prevent entry of the germs into the tooth socket. Bacteria may get out control and may cause periodontal disease. If the pulp is exposed, special materials maybe applied to help the pulp recover from the irritation of the procedure and to form a firm base for the amalgam, inlay or other restorative substance that becomes filling.
Many dentist believed that ceramics could provide more natural-looking restorations. With ceramics, also teeth would be less sensitive to changes of temperature – a problem with some more traditional materials.
