What is a  Filling?

A filling is a way to restore a tooth damaged by decay or fracture back to its normal function and shape. When a dentist gives you a filling, he or she first removes the decayed tooth material, cleans the affected area, and then fills the cleaned out cavity 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-coloured fillings), and an amalgam (an alloy of mercury, silver, copper, tin and sometimes zinc).

Which Type of Filling is Best?

No one type of filling is best for everyone. What’s right for you will be determined by the extent of the repair, whether you have allergies to certain materials, where in your mouth the filling is needed, and the cost.

If decay or a fracture has damaged a large portion of the tooth, a crown, or cap, may be recommended. Decay that has reached the nerve may be treated: through root canal therapy (in which  nerve tissue is removed).
