🦷 What Is the Lifespan of a Root Canal?
A properly done root canal can last a lifetime, but several factors influence how long it stays healthy and functional.
Typical Lifespan
-
Many root canals last 10 to 15 years or more with good care.
-
Some patients keep their treated tooth for their entire life.
Factors That Affect Longevity
-
Quality of the root canal treatment — thorough cleaning, shaping, and sealing
-
Final restoration — placing a strong ceramic crown or filling protects the tooth from fractures
-
Oral hygiene habits — brushing, flossing, and regular dental visits prevent new decay
-
Avoiding trauma — teeth with root canals can be more brittle and need protection from injury
-
Overall health and habits — smoking, diet, and systemic health affect healing
