How long will my tooth last after root canal therapy?

Dante A. Gonzales, DMD
Orthodontics & Dentofacial Orthopedics
A tooth with a root canal can be weaker than a healthy tooth without a root canal. However, teeth with root canals can last a lifetime if taken care of. The support structures like the bone and ligaments are still intact and healthy. But, if not taken care of, the tooth could suffer periodontal disease, recurrent decay, recurrent abscess, or fractures that could cause premature loss. It is important to maintain good oral hygiene and visit your dentist.

Most teeth that have undergone a root canal treatment will last a lifetime. They will last unless the roots decay, the entire tooth cracks or moves, or advanced periodontal disease requires the tooth to be extracted.

Your restored tooth after root canal therapy could last a lifetime, if you continue to care for your teeth and gums. However, regular checkups are necessary. As long as the root(s) of a treated tooth are nourished by the tissues around it, your tooth will remain healthy.
