Specializing in the therapy, research and diagnosis of root canals, Dr. Spradley is dedicated to providing the most comprehensive service in a relaxed and inviting environment.


The proper dental terminology for a “root canal” is root canal therapy or endodontic therapy. This procedure is required when the small amount of tissue in the middle of a tooth becomes infected. The infection is typically caused by tooth decay. The phrase root canal actually refers to the tiny space, or canal, that houses this soft tissue in the root of a tooth. In most cases root canal therapy only requires local anesthesia (normal dental numbing), however our office can provide nitrous oxide (laughing gas) and oral sedation. During the procedure the soft tissue inside the tooth is removed and the entire space is disinfected. The space is then filled and sealed with a material to prevent reinfection.


Root canal therapy has an extremely high success rate. There are some instances that the root canal therapy must be retreated.This procedure is very similar to first time root canal therapy. It involves removing the material filling the root canal space where the soft tissue once resided. The space is then disinfected and filled with a material just as it was during the first root canal therapy.


When the soft tissue inside the tooth is infected, the source of infection usually stays inside the tooth. If there is a source of infection outside the tooth then endodontic surgery may be required. Like root canal therapy surgery is typically performed using only local anesthesia, but nitrous oxide (laughing gas) and oral sedation are available. Endodontic surgery disinfects the area around and on the tooth’s surface by physically removing the infected portion at the end of the root.
