Endodontic treatment is necessary when the pulp becomes inflamed or infected. The most common reasons for inflammation or infection are deep cavities (caries), repeated dental procedures, or cracks. Trauma can also cause inflammation and often shows up as discoloration of the tooth. If pulpal inflammation or infection are left untreated, it can lead to an abscess, resulting in swelling and/or pain.
During the endodontic treatment, a local anesthetic will be given. A sheet of latex called the "rubber dam" (we've got nonlatex ones too) will be placed around the tooth to isolate it, hence keeping it clean and dry during treatment. The treatment consists of three or four basic steps, but the number of visits will depend on your particular case. Some treatments take 2 visits but many are just a single visit. Occasionally 3 appointments are needed. In any case, it depends on the degree of infection/inflammation and degree of treatment difficulty. To us, it's more important to do it the very best we can than to meet a specific time criteria.
There are, of course, no guarantees. Root canal or endodontic therapy has a very high degree of success. Studies have consistently shown the teeth with good root canal therapy and crown have long-term success rate up to 90%. We will discuss with you the chances of success before any endodontic procedure to help you make an informed decision. If a root canal or endodontic therapy is unsuccessful or fails you still have options.
Occasionally a tooth that has undergone endodontic treatment fails to heal or pain continues despite therapy. Although rare, sometimes a tooth initially responds to root canal therapy but becomes painful or diseased months or years later. When either of these situations occur, the tooth often can be maintained with a second endodontic treatment.
Generally, a root canal is all that is needed to save teeth with injured pulp from extraction. Occasionally, this non-surgical procedure will not be sufficient to heal the tooth and your endodontist will recommend surgery. Endodontic surgery can be used to locate fractures or hidden canals that do not appear on x-rays but still manifest pain in the tooth. Damaged root surfaces or the surrounding bone may also be treated with this procedure. The most common surgery used to save damaged teeth is an apicoectomy or root-end resection.
