Why does my filling need replacing?

There is no perfect substitute for a natural,healthy tooth.A filling, no matter what the material, may last for many years but eventually will wear out and need replacing. Constant stress from chewing forces and temperature cycling from hot and cold foods affects fillings. Clenching or grinding puts  tremendously more force on fillings as well as tooth enamel.If the filling doesn't outright crack or break, it chips or pulls away from the tooth enamel next to it. This allows bacteria to enter the crevices and cause the hidden areas to decay over time.
