1. Use of a rubber dam - a barrier that reduces our patient‚s exposure to amalgam slurry that is created when the filling is drilled out.
2. Use of high volume suction - both over and under the rubber dam to reduce our patient‚s exposure to mercury vapor
3. Option of pure oxygen - for our mercury sensitive patients who may need an alternative source of air.

We also have a special amalgam filter that separates and isolates the old mercury fillings so that they can be disposed of properly.

Due to questions concerning the safety of mercury (amalgam) fillings, the Peninsula Center of Cosmetic Dentistry does not use amalgam in its practice. Instead, PCCD uses dental composites - hard plastic that bonds to teeth. Amalgam fillings, which have been around since the 1870s, are now considered a less optimal material. Since composites come in the color of teeth, they look much better than silver fillings. Composites are very safe, very effective and are now BPA-free as well.

While some studies have shown mercury in amalgam fillings can leach into the mouth, studies vary widely on the amount or its effect on humans. Nevertheless, mercury from labs and dental practices contribute to increased levels of the toxic metal in wastewater and the environment. Dr. Field and the Peninsula Center of Cosmetic Dentistry are proud to put the environment and patient health first by using the latest technology in filling materials.
