Root canal therapy is extremely effective at removing infection and saving a natural tooth. But that doesn’t mean that same tooth can never become infected again down the road.
Yes, a tooth can become re-infected after root canal therapy in Palatine, IL, though it’s worth noting that this is relatively uncommon. These new infections usually result from new decay, a cracked restoration, or bacteria finding their way back into the tooth.
Why Reinfection Can Happen
During root canal treatment, the infected pulp is removed, and the canal is thoroughly cleaned and sealed. While this process is highly effective, it doesn't make the tooth completely immune to future problems. If bacteria find a new pathway into the tooth, whether through a cracked crown, a loose filling, or new decay along the gumline, infection can develop again.
Common Causes of Reinfection
A few specific issues tend to be behind most cases of reinfection:
- A crack or fracture in the tooth or its restoration that allows bacteria to enter
- New decay developing around the edges of an old filling or crown
- An additional, previously undetected canal that wasn't fully treated
- A restoration that's failed or become loose over time
Signs You Should Watch For
Symptoms of reinfection are often similar to the original problem: sensitivity, pain, swelling, tenderness when biting down. Any of these symptoms after root canal treatment warrant a prompt evaluation.
Knowing Your Treatment Options
If reinfection does occur, Dr. Michael Subtelny may recommend re-treatment of the root canal, an apicoectomy to address infection at the tip of the root, or, in cases where the tooth can no longer be saved, extraction and replacement.
