In general, root canal therapy is an incredibly successful and effective treatment to address the presence of an infection in the pulp of a patient’s tooth. However, in some rare cases a root canal treatment can fail. Therefore, it is important for any root canal patients to know all of the failed root canal symptoms, allowing you to quickly identify if you need additional treatment.
Causes of Root Canal Treatment Failure
Before we dive into the signs and symptoms of root canal treatment failure, let’s discuss some of the causes that lead to it. Some common reasons for root canal treatment failure include:
- Incomplete removal of the infected pulp tissue during the initial root canal treatment
- Presence of complex canal anatomy that was not addressed during the initial root canal treatment
- Cracks or fractures in the tooth that allow bacteria to re-enter and infect the tooth
- Poor restoration of the tooth after root canal treatment
At University Dental, our team of endodontists are experts in root canal therapy, and they can quickly identify any failed root canal symptoms. Below, we list some of the most common signs and symptoms of root canal treatment failure.

Signs and Symptoms of Root Canal Treatment Failure
It is important to monitor your tooth after root canal treatment for any signs of failure. Here are some common symptoms to look out for:
1. Persistent Tooth Pain
Following root canal treatment, it is expected for there to be some discomfort. However, any pain should not be too severe and should subside in a few days. If the pain persists or if it is very severe, it is possible that bacteria has found its way back into the canal and the tooth is once again infected.
2. Discharge from the Tooth
In certain situations, the treated tooth may discharge fluids following root canal treatment. This is a failed root canal symptom, as the discharge usually indicates an abscess has formed in the tooth as a result of an infection.
3. Tooth Sensitivity
If there is an issue with the root canal treatment, the infected tooth will be incredibly sensitive to temperature and pressure. That means cold and hot foods or beverages will be unbearable to eat or drink, and any pressure on the tooth will result in immediate discomfort.
4. The Tooth Changes in Appearance
Discoloration of the tooth is another sign of root canal treatment failure. The tooth may appear darker than the surrounding teeth or have a grayish tint.
5. Sinus Issues
Oftentimes the infection in your tooth can spread to other areas of the body, including in the form of a sinus infection. If you suddenly are experiencing a runny nose, sinus congestion, bad breath, or jaw pain, it could be a sign that root canal treatment was ineffective and the infection in your tooth is spreading.
6. Swelling
If the infection is still present in the tooth following root canal treatment, you can expect some swelling in the area surrounding the tooth.
What to Do If You Suspect Root Canal Treatment Failure
If you have any of the above failed root canal symptoms following root canal treatment, it is essential to see our endodontist in San Diego as soon as you can. Treatment will be required to address the infection in the pulp of the tooth before the symptoms can worsen. Our dentist will examine the tooth and take X-rays to determine the cause of the problem. Depending on the severity of the issue, our dentist may recommend one of the following treatments:
Endodontic retreatment: This involves removing the existing root canal filling, cleaning the canals, and refilling them with new material.
Apical surgery: In cases where endodontic retreatment is not possible, our dentist may recommend apical surgery. This involves removing the infected tissue and the tip of the root.
Extraction: In cases where the tooth cannot be saved, extraction may be necessary.
