The lifespan of a dental restoration depends on the type of treatment, the materials used, and how well you care for your oral health. Tooth-colored fillings may last several years, while dental crowns, bridges, and implants can often last 10 years or longer with proper maintenance. Good oral hygiene, regular dental checkups, and avoiding habits such as chewing ice, biting hard objects, or grinding your teeth can help extend the life of your restoration.
