BPA Free, Metal Free Fillings & Bondings
Many people seek the aesthetic aspect of composite fillings and bondings, and yes, metal free fillings are more attractive. However, there are far greater health advantages to using Bishphenol A (BPA) and metal free fillings and bondings.
Scientists agree that dental amalgam fillings (also known as silver or metal fillings which contain 50% mercury) do leach mercury into the mouth, and may contribute too many health issues. Bishphenol A, better known as BPA, is a controversial chemical found in plastics which has also been linked to health illnesses. Dental resin materials, like composite fillings and bondings, contain BPA. Similar to metal fillings that leach mercury, studies found oral enzymes from saliva release BPA from resin dental materials.
Health-conscious patients want safe alternatives and are seeking not only metal free alternatives, but BPA free as well. Dentists have an option when choosing their products and BPA FREE resin materials can be selected. Dr. Aver uses only BPA FREE materials.
Conserving a patient’s natural tooth and using safe materials has always been of the utmost importance to Dr. Aver. This is why she uses only Bishphenol A (BPA) free and metal free fillings and bondings.
BPA free composites are the best alternative to amalgam fillings. Amalgam fillings expand and contract with the changing temperature of your 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 verses amalgam with are placed in your tooth, and are not affected by changing temperatures allowing them to hold up under daily wear.
Composite resin or metal free fillings are also a more conservative option since Dr. Aver removes less of the healthy, natural tooth for composite fillings/bondings verses amalgam. All of this results in a longer life span of the filling.
Benefits of BPA, Metal-Free Fillings & Bondings

- Bonds to the tooth restoring strength
- More stable than mercury amalgam
- Provides a tighter seal
- More resistant to fracturing
- Does not react to temperature changes resulting in weakening of the tooth like amalgam
- Aesthetically pleasing tooth appearance
- Take less time to harden than amalgam fillings
