We Resolve Failed Root Canals with Endodontic Re-treatment

An expertly administered root canal has a very high success rate. However, a root canal can fail over time. The possible causes of root canal failure include:

• Narrow or curved root canals not treated in the initial procedure
• Complicated canals that were missed previously
• Delayed crown placement after the treatment
• A cracked crown or filling can expose the tooth to new infection
• New decay can cause harmful bacteria to infiltrate the tooth

It can be tricky to identify a failed root canal because symptoms vary. Sometimes, it can be sensitive to pressure. Other patients may experience an achy sensation around the treated tooth. In extreme cases, patients may experience facial swelling or extreme throbbing. Your tooth could be asymptomatic, but routine dental care may catch the problem before it worsens.

Root canals have a high success rate, but proper care is essential to prevent complications and ensure long-term success. Here’s how you can protect your treated tooth and avoid a failed root canal:

• Don’t delay crown placement: After a root canal, the tooth is weakened and more prone to fractures. A dental crown or other permanent restoration helps protect the tooth, prevent re-infection, and restore full function. Delaying this step can increase the risk of failure.
• Maintain excellent oral hygiene: Your treated tooth is vulnerable to harmful bacteria like other teeth. Brush twice a day and floss daily to prevent plaque buildup and bacteria from entering the treated tooth. A clean mouth reduces the risk of re-infection.
• Get regular dental check-ups: Routine visits allow your dentist to monitor the treated tooth, check for signs of re-infection, and ensure the crown or filling remains intact.
