Can a Root Canal fail?

Root canal treatment is often the go-to solution for saving an infected or damaged tooth. While it's highly successful, many people still wonder: Can a root canal fail? The short answer is yes, but failures are rare and often preventable or treatable.

If you're considering or have had a root canal treatment in Woodbridge, this guide will help you understand how and why failures can happen — and what your next steps should be.

What Is a Root Canal?

A root canal is a dental procedure used to treat infection inside the tooth. The dentist removes the damaged pulp, disinfects the root canals, and seals the tooth to prevent future infections. When done correctly, root canals can save natural teeth and eliminate pain.

Can a Root Canal Really Fail?

Yes, even though modern techniques have made root canals more reliable, there’s still a 5%–15% failure rate depending on the case.

Common Causes of Root Canal Failure:

• Incomplete removal of the infection

• Missed canals or complex anatomy

• Fractures or cracks in the tooth

• Leakage of the restoration or crown

• New decay or trauma after treatment

Signs Your Root Canal May Have Failed

If you're experiencing any of the following symptoms after treatment, it's important to consult a dentist in Woodbridge:

• Persistent pain or pressure

• Swelling in the gums or jaw

• Discoloration of the treated tooth

• A recurring pimple or abscess near the treated area

• Sensitivity to hot or cold months after the procedure

What Happens If It Fails?

A failed root canal doesn’t necessarily mean losing the tooth. Options may include:

• Retreatment: Cleaning and sealing the canals again

• Apicoectomy: Minor surgery to remove the infected root tip

• Extraction and replacement: Using a dental implant or bridge

An experienced Woodbridge dentist can evaluate your specific case and recommend the best solution.

How to Prevent Root Canal Failure

• Always complete the treatment, including the final crown

• Maintain excellent oral hygiene

• Avoid chewing hard foods on the treated tooth until it’s fully restored

• Visit your dentist in Woodbridge regularly for checkups

Final Thoughts

Root canal failure is uncommon, but it can happen. Understanding the signs and seeking timely care from a qualified Woodbridge dentist can make all the difference in preserving your smile. If you suspect something isn’t right after your procedure, don’t ignore it. Early intervention can often save the tooth — and prevent more serious issues down the road.
