How Long Do Teeth Survive After Root Canal?

How Long Do Teeth Survive After Root Canal?

If you're considering or have already undergone a root canal, you may wonder, "How long will my tooth survive after the treatment?" According to a study conducted by the Regenstrief Institute and Indiana University School of Dentistry, the average survival time of a tooth after a root canal is about 11.1 years. However, this timeline can be extended with additional treatments and proper dental care.


The study, which analyzed data from over 46,000 patients across 99 dental offices in the United States, found that the median survival time of a tooth after a root canal is 11.1 years. However, several factors can impact this, such as whether the tooth receives a filling or crown after the root canal treatment. On the other hand, neglecting restorative procedures may lead to the tooth's quicker deterioration.


Regional differences also played a role in the survival rates of treated teeth, with root canals lasting longer in the Northeast compared to the West. The study also highlighted that a patient's insurance status could significantly affect the outcome of the procedure. These insights can help inform dental practices and dental insurance policies, ensuring better treatments for patients.


The Importance of Dental Care After a Root Canal

Dr. Patricia Silva, DDS at By The Lake Dental, explains, “Best practice is to maintain good oral care at home and regular hygiene visits to prevent root canals. But once it happens, we must treat the root canal properly to try to save the affected natural teeth. Sometimes additional procedures such as fillings and crowns can be used to increase the effectiveness of the treatment. An untreated root canal can develop into an abscess (infection) leading to the removal of the dead tooth, followed by implants”. By following up with your dentist and ensuring any necessary restorative treatments, you can maintain the health of your teeth and gums.
