Indefinitely .. many factors will influence the long term prognosis of the tooth. A tooth well restored with a good root canal may last a lifetime in a healthy patient.

This really depends on a lot of factors. By and large, root canals can be very successful, about 95% of the time the tooth will have considerable longevity. 10 years or more is a successful root canal. Some can last 4 or 5 decades. 5% of root canals do fail. They fail due tooth or root fracture, or recurrent decay from poor home care. Root fracture is not treatable. Short of good home care and being certain to crown the tooth that has a root canal in a timely fashion, there is nothing you can do to prevent that from happening. So there is that unpredictability to one in twenty teeth that have a root canal. Speak to your dentist, they may be able to give you a relative risk assessment of the tooth and a prognosis for the outcome. Best, Dr. Ted

Hello! Root canaled teeth can last for decades if the tooth is crowned and taken care of properly. It all depends on the case, and how the root canal was performed.
