Can a root canal fail?

Root canal treatment is highly successful, with success rates typically above 90%. However, like any medical procedure, it’s possible for a root canal to fail in some cases. Understanding why failure might happen can help you take steps to protect your dental health.

Reasons a Root Canal May Fail

Incomplete Cleaning: If all the infected tissue isn’t fully removed or canals are missed, bacteria can remain and cause reinfection.
New Decay: If the tooth develops new decay or the restoration (filling or crown) fails, bacteria can enter and infect the root again.
Cracked Tooth: Cracks in the tooth can allow bacteria to bypass the root canal treatment.
Complex Root Anatomy: Some teeth have complicated canals that are difficult to clean thoroughly.
Delayed Restoration: Not placing a permanent crown or filling promptly can leave the tooth vulnerable.

Signs of Root Canal Failure

Persistent or worsening pain
Swelling or tenderness near the treated tooth
Formation of an abscess or pus
Tooth discoloration or mobility

What to Do If a Root Canal Fails

If you suspect your root canal has failed, visit your dentist or endodontist promptly. They may recommend:

Retreatment of the root canal
Apicoectomy (surgical cleaning of the root tip)
Tooth extraction if saving the tooth isn’t possible

Conclusion

While root canal failure is uncommon, it can happen. Timely treatment, good oral hygiene, and regular dental check-ups are essential to maintain the health of your treated tooth.
