Fillings

Over the years there has been some concern as to the safety of amalgam (silver) fillings. An amalgam is a blend of copper, silver, tin and zinc, bound by elemental mercury. Dentists have used this blended metal to fill teeth for more than 100 years. The controversy is due to claims that the exposure to the vapor and minute particles from the mercury can cause a variety of health problems.

According to the American Dental Association (ADA), up to 76% of dentists use silver containing mercury to fill teeth. The ADA also states that silver fillings are safe and that studies have failed to find any link between silver containing mercury and any medical disorder.

The general consensus is that amalgam (silver) fillings are safe. Along with the ADA’s position, the Center for Disease Control (CDC), the World Health Organization, the FDA, and others support the use of silver fillings as safe, durable, and cost effective. The U.S. Public Health Service says that the only reason not to use silver fillings is when a patient has an allergy to any component of this type of filling. The ADA has had fewer than 100 reported incidents of an allergy to components of silver fillings, and this is out of countless millions of silver fillings over the decades.

Although studies indicate that there are no measurable health risks to patients who have silver fillings, we do know that mercury is a toxic material when we are exposed at high, unsafe levels. For instance, we have been warned to limit the consumption of certain types of fish that carry high levels of mercury in them. However, with respect to amalgam fillings, the ADA maintains that when the mercury combines with the other components of the filling, it becomes an inactive substance that is safe.

There are numerous options to silver fillings, including composite (tooth-colored), porcelain, and gold fillings. We encourage you to discuss these options with your dentist so you can determine the best option for you.

Although the U.S. Public Health Service issued a report in 1993 stating there is no health reason not to use amalgam (silver fillings), more patients today are requesting “white” or tooth-colored composite fillings. We also prefer tooth-colored fillings because they “bond” to the tooth structure and therefore help strengthen a tooth weakened by decay. White fillings are also usually less sensitive to temperature, and they also look better. However, “white” fillings cannot be used in every situation, and if a tooth is very badly broken-down, a crown will usually be necessary and provide better overall satisfaction for the patient.
