Filling
What is a Filling?
A filling is one way to restore a damaged tooth from decay and back to its normal function and shape. As you are given a filling, the decayed tooth material is removed first, as followed by a cleaning to the affected area, and the cleaned out cavity is then sealed off with a filling material.
By closing off spaces where bacteria can enter, a filling also helps prevent further decay. Materials used for fillings include gold, porcelain, a composite resin (tooth-colored fillings), and an amalgam (an alloy of mercury, silver, copper, tin and sometimes zinc).
Signs and symptoms you may need a filling:
A visible, open hole in your tooth surface
A brown or black stain on your tooth which can’t be removed
Acute, sharp pain when you bite down or eat
Throbbing or aching when you eat or drink hot, cold, or sweet foods or beverages
A toothache that does not go away
Fillings are sometimes necessary to replace an old filling that has begun to leak. Signs and symptoms of a leaking filling are similar to those listed above, and you also need to look for:
A filling that is chipped, cracked, or broken
A crumbling, broken margin where the filling meets your tooth surface
