Dental science deals with diseases that inflict a person's mouth – especially the teeth. There are different kinds of dental illnesses and most can be treated with externally with the help of dental tools or medicine. However, some illnesses are grave and require dental surgery to ensure proper healing and repair.
The most common of all dental surgery is the extraction of a tooth. Simple extracts can be done by a dentist or an oral surgeon and are performed on teeth that are visible in the mouth, usually under local anesthetic. Surgical extracts involve the removal of teeth that are not easily accessible, either because of a crack under the gum line or because it is affected. Thedentist makes an incision into the gum to reach the tooth, and this sometimes may also require the removal of overlying bone tissue with a drill.
Another common reason for a dental surgery is to insert a new fake tooth or a dental implant. Sometimes a deep cavity in the tooth can only be filled with an implant or the tooth is extract fully and replaced by a fake tooth through surgery. This surgery also needs local anesthesia, as the pain is probably too much for a patient to withstand.
Although, the above mentioned are the most common reasons for a dental surgeon, there are cases where surgery must take place for other reasons too. These would include, fitting braces on extremely uneven teeth to bring them to an even formation, fitting permanent dentures, for root canal treatment and other types of procedures on gums.
