Most adults have had traditional amalgam fillings – the (silver) or gold filling types of tooth restoration. Some silver fillings, also called mercury fillings, and some amalgam fillings contained mercury. Metal-type fillings were effective, but have been known to cause several issues. One being to blacken in color over time, the other a cracking of the tooth itself due to hot and cold expansion issues.
Composite resin dental fillings were developed as a much improved alternative to traditional metal tooth fillings. These are tinted to look like a natural tooth and are made of a plastic dental resin.
Composite resin dental fillings are life-like, strong, durable, and make for a very natural looking smile. Best of all, many dental insurance plans cover their use.
