Composite fillings are usually more expensive than traditional amalgam fillings because they require a more sophisticated process, more expensive materials and additional office equipment. Composite materials offer an esthetic alternative to traditional amalgam materials. Composites are more likely to be used on more-visible front teeth. Composites bond to the tooth to support the remaining tooth to help prevent breakage.

Composite insulate the tooth from excessive temperature changes. Composites (white fillings) last about 8 years with a range of 7-10 years. Composite fillings restore the natural appearance of the tooth. Composites require less removal of tooth structure. Composite fillings, if they are done correctly, take about 60% longer, require special expertise and expensive materials, and are more difficult to place, and so they cost considerably more than silver.

Composite requires the use of special bonding technology that many dentists are uncomfortable with. Composite resin dental fillings were created as an alternative to traditional metal dental fillings. Composites are not only used for restoring decay, but are also used for cosmetic improvements of the smile by changing the color of the teeth or reshaping disfigured teeth. Composite resin fillings are strong, durable, and make for a very natural looking smile.

Composite fillings are usually more expensive than traditional amalgam fillings because they require a more sophisticated process, more expensive materials and additional office equipment. As such, people who have previously received amalgam fillings often return to their dentist to have them replaced with composite fillings.
