A root canal aims to relieve pain and save a damaged or infected tooth, so it can be confusing when that same tooth starts hurting again years later. Does new discomfort mean the root canal failed? Not necessarily, but persistent pain is a sign that the tooth should be evaluated.
At Hampton Dental Associates, Dr. Richard Winter has extensive training in advanced restorative, reconstructive, and implant dentistry. He has completed 1,000+ hours of continuing education, earned Mastership in the Academy of General Dentistry, and holds Diplomate status with the American Board of Oral Implantology/Implant Dentistry.
A New Infection May Develop
Although root canal treatment removes infected tissue from inside a tooth, bacteria can sometimes reenter the area. This may happen if a filling or crown becomes damaged, loose, or worn, allowing bacteria to reach the treated tooth.
Signs of a possible infection can include:
- Pain or tenderness when biting
- Swelling around the tooth
- Gum sensitivity
- A small bump on the gums
- Persistent aching or pressure
The Tooth May Have a Crack
A root canal-treated tooth can become more vulnerable to fractures, particularly if it has lost a significant amount of natural tooth structure. Small cracks may not cause symptoms immediately but can worsen over time.
A crack may allow bacteria to enter the tooth or irritate the tissues surrounding its root. Pain that occurs primarily when chewing or releasing your bite can sometimes be associated with a cracked tooth.
An Untreated Canal May Be Present
Teeth can have complex internal anatomy. Some have additional or unusually shaped canals that can be difficult to detect during the original treatment. If bacteria remain inside an untreated canal, symptoms may appear months or even years later.
In some situations, retreatment may address the remaining infection and preserve the tooth.
The Surrounding Tooth or Gum May Be the Problem
Pain near a root canal tooth does not always originate from that tooth. Gum disease, decay in a neighboring tooth, bite problems, or inflammation around the root may create discomfort that feels like it is coming from the previously treated tooth.
A dental exam and imaging can help identify the true source.
