An increasingly popular alternative to silver, amalgam fillings are composite, white fillings. Unlike amalgam fillings, composite fillings are virtually unnoticeable. They are shade matched according to the color of your teeth to help create a beautiful, white smile and restore areas of decay. Composite may also be used for bonding teeth. Bonding is a conservative way to repair slightly chipped, discolored, or crooked teeth. During dental bonding, a white filling is placed onto your tooth to improve its appearance.
