Endodontics is a specialized branch of dentistry that deals with the complex structures found inside the teeth. The Greek word “Endodontics” literally means “inside the tooth” and relates to the tooth pulp, tissues, nerves, and arterioles.
Reasons for endodontic treatment:
Endodontic treatment (or root canal therapy) is performed to save the natural tooth. In spite of the many advanced restorations available, most dentists agree that there is no substitute for healthy, natural teeth.
Some reasons your dentist may recommend having endodontics, or a root canal;
Oral bacteria is the most common cause of endodontic problems. Bacteria invade the tooth pulp through tiny fissures in the teeth caused by tooth decay or injury. The resulting inflammation and bacterial infection jeopardize the affected tooth and may cause an abscess to form.
Fractures and chips
When a large part of the surface or crown of the tooth has become completely detached, root canal therapy may be required. The removal of the crown portion leaves the pulp exposed, which can be debilitating painful and problematic.
Injuries to the teeth can be caused by a direct or indirect blow to the mouth area. Some injuries cause a tooth to become luxated or dislodged from its socket. Root canal therapy is often needed after the endodontist has successfully stabilized the injured tooth.
Inflammation and tenderness in the gums.
Teeth that are sensitive to hot and cold foods.
Tenderness when chewing and biting.
Unexplained pain in the nearby lymph nodes.
Root canal therapy usually takes between one and three visits to complete. Complete X-rays of the teeth will be taken and examined before the treatment begins.
Initially, a local anesthetic will be administered, and a dental dam (protective sheet) will be placed to ensure that the surgical area remains free of saliva during the treatment. An opening will be created in the surface of the tooth, and the pulp will be completely removed using small handheld instruments.
The space will then be shaped, cleaned, and filled with gutta-percha. Gutta-percha is a biocompatible material that is somewhat similar to rubber. Cement will be applied on top to ensure that the root canals are completely sealed off. Usually, a temporary filling will be placed to restore functionality to the tooth prior to the permanent restoration procedure. During the final visit, a permanent restoration or crown will be placed.
