Root Canal Retreatment
What Is a Root Canal?
When an infection occurs inside your tooth, treatment is needed right away. The only way to remove the bacteria and eliminate the infection is with a root canal. This procedure is done under a local anesthetic. An access hole is drilled into the top of the tooth, and small tools are used to remove the infected pulp and the nerve. Next, the canals inside the tooth are shaped and cleaned, and the entire interior of the tooth is disinfected. A special filling material called gutta percha is placed inside the space to seal the canals and finally a crown is placed on the tooth to provide strength and protection.
What Causes Root Canal Failure?
While root canals have a high success rate, there are still some instances in which the treatment can fail. Common causes for root canal failure include:
Root Canal Retreatment
If your initial root canal treatment fails, retreatment becomes necessary. This treatment can generally be completed in one to three visits. First, a local anesthetic is administered. A rubber dam is placed around the tooth to isolate it and prevent contamination. Next, the original restoration is removed, followed by the material inside. We use small, specialized tools to clean and reshape the canals. We may take x-rays to ensure that we have cleaned each one. Depending on your situation, a medicated material may be placed inside the space to help eliminate any bacteria that may still be lingering, and a temporary crown is placed. During the next visit, this material will be removed, and the tooth is cleaned out once again. Then we place new gutta percha inside the tooth and place a new crown.
Successful retreatment can function normally for many years to come and may even function properly for the rest of your life. This option is always preferable to extraction as it allows the tooth to stay in the socket and enables it to continue helping to keep your jawbone strong and healthy.
If you have previously undergone a root canal and the tooth is causing you pain or other complications, you may need root canal retreatment. For more information, and to schedule your appointment, call Blue Summit Dental Group today at (810) 658-9177.
