What causes a discolored filling?

Discolored fillings may be caused by leaking around the edges of a filling or staining from things we put in our mouth. When fluids leak underneath a filling, staining and decay may develop. Leakage may appear as a dark line around the edge of the filling or a dark area underneath the filling itself. White fillings may turn a darker color over time from smoking, drying out or exposure to high staining foods or drinks.
