Amalgam (mercury) material may have been the choice for fillings at one time but tooth colored (resin) have become the "state of the art" material for fillings.
A tooth colored filling is a composite resin that is used as an alternative to amalgams. This is an excellent cosmetic option for those patients who do not want the look of silver in their mouths. Tooth colored fillings can be used on teeth that are decayed, cracked, or stained.
Composite or resin fillings are strong and durable and make for a natural looking smile.
