You depend on your family dentist for most of your oral care. There are some situations, though, that are best handled by a specialist. If you or a family member has a deeply decayed tooth, for example, it might be in your long-term interest to see an endodontist. From the Greek words, endo (“within”) and odont (“tooth”), endodontics focuses on dental care involving a tooth’s interior layers, including the pulp, root canals and roots. While general dentists can treat many endodontic problems, an endodontist has the advanced equipment and techniques to handle more complex cases. The majority of an endodontist’s work involves teeth inwardly affected by tooth decay. The infection has moved beyond the initial cavity created in the enamel and dentin layers and advanced into the pulp and root canals. The roots and underlying bone are in danger of infection, which can endanger the tooth’s survival. The most common treatment is root canal therapy, in which all of the infected tissue is removed from the pulp and root canals. Afterward, the empty spaces are filled and the tooth is sealed and crowned to prevent future infection. General dentists can perform this treatment, primarily with teeth having a single root and less intricate root canal networks. But teeth with multiple roots are a more challenging root canal procedure. Teeth with multiple roots may have several root canals needing treatment, many of which can be quite small. An endodontist uses a surgical microscope and other specialized equipment, as well as advanced techniques, to ensure all of these inner passageways are disinfected and filled. Additionally, an endodontist is often preferred for previously root-canaled teeth that have been re-infected or conditions that can’t be addressed by a traditional root canal procedure. While your dentist may refer you to an endodontist for a problem tooth, you don’t have to wait. You can make an appointment if you think your condition warrants it. Check out the American Association of Endodontists webpage www.aae.org/find for a list of endodontists in your area. Advanced tooth decay can put your dental health at risk. But an endodontist might be the best choice to overcome that threat and save your tooth.
