Non-Metal Fillings

 Composites, if placed with exacting techniques (rubber dam isolation and modern bonding agents), get as close as we have ever been able to restore the tooth to its original strength in the most conservative fashion. The composites are a very hard plastic that bonds (micromechanically fuses) to the tooth to hold the tooth together. Amalgams have multiple disadvantages. Amalgam is a metal which expands and contracts with hot, cold and biting. Therefore, with every meal the teeth are being weakened and over time and depending on the size of the filling, the tooth becomes susceptible to fracturing. Amalgam also contains mercury which is a very toxic element.
