symptoms of a bad tooth
Excessive pain and swelling past the normal root canal healing period indicates a problem. An infected root canal may require a second root canal procedure. Dental insurance may cover part of the expenses associated with a root canal. Symptoms of a bad root canal may include fever. Dentists use a root canal to remove the nerve and pulp of a tooth that has become diseased or infected.
Extreme Pain. For most people the first recognizable symptom of a bad root canal is pain, though itâs important to note that some pain is normal after even a perfect root canal. The procedure is invasive and patients often experience discomfort for a week or more. Pain is only usually a problem when it doesnât go away or gets worse.
