Many people like the idea of tooth-colored fillings that can be “hidden” in the smile. While metal-free restorations are indeed more attractive, there are also health advantages that come from the selection of BPA free fillings.

Research has demonstrated that an amalgam filling is approximately 50 percent mercury in content. Additional research has shown that mercury vapor is released into the mouth when fillings are heated through the friction of chewing. Composite resin fillings have provided an alternative solution to tooth damage. There are, however, concerns that Bisphenol A, or BPA, in the plastic composition of resin fillings could pose a risk to health and wellness. BPA may be released from fillings through contact with saliva and oral enzymes.

We are a health-conscious natural dental practice. As such, our team believes is using only the safest mercury-free materials in the restoration of teeth. At Sacramento Natural Dentistry, only BPA-safe materials are used in the care of your smile.

While the natural appearance of a composite dental filling is very advantageous, your biological dentist primarily uses this material for its safety and efficacy. In addition to being a healthier option than mercury amalgam fillings, the composite restoration is also kinder to tooth structure. Because amalgam fillings contain metal, they expand and contract more than natural enamel. This movement of the filling material gradually causes fractures in the weakened tooth wall, allowing microbes to get beneath the filling where they can cause infection. Our BPA-safe composite restorations are similar to enamel in the way they respond to temperature change. The repair process is also different, with bonding achieving tighter margins through which bacteria cannot gain access to hidden areas.
