BPA Free, Metal Free Fillings 

Are you seeking the aesthetic aspect of composite fillings, do you want to be free of metal fillings? Dental amalgam fillings(also know as silver or metal fillings which contain 50% mercury) do leach mercury into the mouth, and may contribute to many health issues. Dr. Harbin & Dr. Jones only use (BPA) free and metal free fillings. 
BPA free composites are the best alternative to amalgam fillings. Amalgam fillings expand and contract with the changing temperature of the mouth (cold/hot drinks/foods). This movement weakens the tooth wall which fractures the tooth allowing bacteria to enter, resulting in dental decay and disease. However, composite materials like white resin or even porcelain, actually bond to the tooth and aren't affected by changing temperatures allowing them to hold up under daily wear. 
Composite resign or metal free fillings are also a more conservative option, which in turn results in a longer life span of the filling.

• More stable than mercury amalgam
• Provides a tighter seal 
• More resistant to fracturing
