Are you experiencing lingering pain or swelling after a root canal? While most root canal treatments are highly successful, occasionally a procedure can fail, leading to discomfort and the need for further attention. In this quick dental care tip, Dr. Nainy Jain, Endodontist at Jaipur Eye & Dental Hospital, explains the common warning signs of a failing RCT and what you should do next.
Why Do Root Canals Fail?
A root canal treatment (RCT) is designed to save an infected or damaged tooth, and the vast majority of these procedures are successful. However, there are a few reasons why an RCT might fail:
- Incomplete Infection Removal: If the initial infection was not completely cleaned out from the complex root canal system, bacteria can multiply and cause the treatment to fail.
- Lack of Proper Restoration: After a root canal, the tooth becomes fragile. If you do not get a permanent filling or a dental crown to restore and protect the tooth, it remains vulnerable to damage and reinfection.
- Reinfection or Tooth Damage: Over time, a new infection can develop, or the treated tooth might crack or break, compromising the seal and allowing bacteria to re-enter.
Warning Signs You Shouldn’t Ignore
It is crucial to monitor your treated tooth. If you notice persistent pain after your RCT, swelling, a gum boil (pus discharge), pain while chewing, or sensitivity that doesn’t go away, do not ignore these symptoms. The good news is that in many cases, a failed root canal can be successfully retreated to save your tooth. Always consult your dentist if you experience any discomfort after an endodontic procedure.
