What are the advantages of composite “white” fillings?
Composite fillings are more natural looking the silver “amalgam” fillings. Composite fillings strengthen the cured tooth. Layers of silicon dioxide, which is a plastic mixture filled with glass are used to fill and stabilize the tooth. Silicon dioxide does not conduct extreme hot and cold temperature like amalgam fillings. Because of this your teeth will not be as sensitive after treatment. Composite fillings harden very quickly after they are placed. Amalgam fillings usually take a couple of hours to harden. Composite fillings save more of the natural tooth structure. When doing an amalgam filling some of the good tooth surface has to be removed in order to wedge the amalgam filling in the tooth.
