Root canals are a highly successful dental procedure, with a 95% success rate that can last patients a lifetime. However, in some cases, root canals may fail due to a variety of factors. These include cracks in the root area, an obstruction that prevents proper cleaning of the root area, or salivary contamination. Symptoms of a failed root canal may include sensitivity to cold or heat, swelling, or pain when chewing.
If you experience any of these symptoms, it is important to contact your dentist immediately. In order to determine the best course of action for a failed root canal, x-rays may be used to guide the endodontist in diagnosing and treating the issue. If traditional root canal treatment is not enough to save the tooth, surgery may be recommended. Alternatively, tooth extraction may be the last option if endodontic surgery is not successful.
To help ensure that your root canal lasts, it is beneficial to place a crown immediately after the endodontic procedure. Additionally, practicing good oral hygiene habits and keeping the area surrounding the root canal clean can help prevent infection and ensure that endodontics last forever. If you have had a failed endodontic treatment, there are options available to aid healing. It is important to remember that the rate of root canal failure is very low and that it is normal to feel some pain after a root canal procedure.
