Root Canal Failure Symptoms
Signs and symptoms of failed root canal therapy include sensitivity to cold or hot, swelling, and/or pain from chewing.
Can a failed root canal be fixed?
With proper care, even teeth that have had root canal treatment can last a lifetime. But sometimes, a tooth that has been treated doesn’t heal properly and can become painful or diseased months or even years after treatment. If your tooth failed to heal or develops new problems, you have a second chance.

What is the failure rate of root canals?
If your dentist can find all the canals on your root canal tooth and properly fills them, a success rate of 95% is reasonable. The main reason why failure happens in not from an inadequately filled root canal, but is from the tooth breaking from not having a recommended crown placed on it following treatment.
Can a tooth with a root canal hurt years later?
In most cases, the sensitivity and discomfort associated with a root canal should go away within a few days. If it does not get better, or if the pain is severe or unrelieved by home measures, it is important to call the endodontist or dentist for an evaluation.
