Six years ago, my dentist performed a root canal procedure on my upper left first molar. The procedure went fine, and the tooth felt comfortable until late September. I hadn’t eaten anything unusual but noticed a dull toothache. Now, the tooth hurts daily, and the pain is getting worse. My dental appointment isn’t until two weeks after the Thanksgiving holiday when I return from vacation. Is a tooth savable if I’ve already had a root canal? – Thanks. Kaitlynn from IN
Kaitlynn,
Root canal failure occurs in 10% of teeth treated. Failure occurs when the tooth doesn’t fully heal and eventually flares up, as is the case for your situation.
Why Might a Tooth Flare Up Years After a Root Canal?
A tooth might become irritated years later if some infected tissue lingers after a root canal. Due to the intricate anatomy of teeth, particularly those with curved or branching roots, removing all infected tissue during a root canal procedure can be challenging. Any residual infection can lead to future complications.
Either root canal retreatment or surgery may be necessary to address root canal failure. A dentist may refer you to an endodontist (specialist in root canal therapy) for retreatment. The goal is to identify and eliminate the source of the persistent infection. While the success rate of retreatment or surgery is often estimated at 50%, the outcomes are usually more favorable.
It’s also possible that the tooth has developed a crack, which could contribute to the ongoing issues. Unfortunately, the prognosis for saving a tooth with a crack is generally poor. If the tooth is unsavable, your dentist will explain tooth replacement options.
