Metal-Free Dentistry

We believe in the importance of patient education. Not only does education help you take better care of your teeth, it also helps you make choices that fit your own philosophy of health care.

Today, one of the most hotly debated issues in dentistry revolves around the use of traditional dental amalgam for cavity fillings. In fact, there have been questions about the safety of amalgam since it was first introduced in the mid 1800s.

What scientific studies say about amalgam

Amalgam is an alloy made up of elemental mercury, silver, tin, copper and other metallic elements. The controversy surrounds the use of mercury which, in some forms, is toxic. In amalgam, mercury combines with other metals to render it safe and stable. The concern has been that, in using amalgam fillings, minute amounts of mercury or mercury vapor may be released, thus putting people, especially children, at risk.

In April 2006, however, the Journal of the American Medical Association (JAMA) presented two scientific studies that compared the health effects of amalgam and composite resin fillings in children. The studies concluded that children with amalgam fillings do not experience adverse effects related to neurobehavioral, neuropsychological (IQ) and kidney function.*

The American Dental Association considers amalgam to be a safe, effective option for treating tooth decay. The National Institutes of Health, the U.S. Public Health Service, the Centers for Disease Control and Prevention, the Food and Drug Administration and the World Health Organization share that opinion.

Our philosophy on metal-free dentistry

As dental professionals, we follow the guidelines laid out by the American Dental Association regarding amalgam: There is no scientific evidence to support the opinion that amalgam is unsafe. Nevertheless, we do support the cause of metal-free dentistry and prefer that our patients choose composite fillings whenever possible.

Composite fillings are a mixture of glass or quartz in a resin, tooth-colored base. They are safe and very durable. The cost is moderate, but they are a bit more expensive than an amalgam. Aesthetically-speaking, a composite is the better choice if you want a more natural-looking filling.
