A root canal (also known as endodontic treatment) is one of the most common dental procedures performed, with well over 14 million done every year. The goal of the procedure is to save your tooth and prevent the need for its replacement with an implant or bridge. The concept of endodontic therapy is based on the idea that we need the roots of our teeth, but once our tooth has formed, we don’t need the soft tissue within the tooth which made our roots.
At the center of your tooth is soft tissue called the pulp. It is comprised of blood vessels, nerves and connective tissue. It has the primary function of forming our teeth and then becomes encased within the hollow areas of our roots (the canals) and the crown (the pulp chamber). Infection and inflammation of the pulp can be caused by trauma to the tooth, deep decay, cracks, chips and even routine restorations. If this happens, severe pain, throbbing, thermal discomfort and possibly even swelling could occur and the patient might have to decide whether to extract the tooth or have the dental procedures necessary to save it. Keep in mind nothing is as good as your natural tooth and as long as it is otherwise healthy, it is almost always better to try and save it. Endodontic therapy is based on the concept that once your tooth is formed, the pulp is no longer essential and if it becomes compromised, it can be removed and your tooth can still be healthy and functional.
If you experience any of these symptoms, your dentist will most likely recommend endodontic treatment to eliminate the diseased pulp. After the tooth has been anesthetized very well, it is isolated with a small protective sheet called a dam, which keeps it clean and free of saliva during the procedure. An opening is made through your filling or crown and the injured pulp is removed using very small cleaning instruments, the canal(s) sterilized with different solutions and the canal system is then sealed with a material called gutta percha. The opening in your tooth is closed with a temporary material, which will stay in place until your dentist sees you. This therapy involves using nothing more than local anesthesia and the goal is to provide you with successful treatment performed in a manner that is acceptable to you. Many times this can be done in one visit, but sometimes the anatomy of your tooth, the biology of your problem, or other factors can cause the need for additional visits. Success for this type of treatment occurs in about 90% of cases. If your tooth is not amenable to endodontic treatment or the chance of success is unfavorable, you will be informed at the time of consultation or if a compromising factor becomes evident during or after treatment.
