How long do fillings last, and when should they be replaced?
Many factors influence the longevity of fillings, including the type of filling material used, the size of the filling, the location of the filling in your mouth, your bite, your oral hygiene, and whether or not you grind your teeth at night. Fillings generally last between 5 and 15 years. Fillings may need to be replaced for a variety of reasons including breakage, wear, recurring decay, or a defective margin (seal).
