FDA Shifts Stance on Mercury in Dental Amalgam

Neil Osterweil

July 17, 2008 The US Food and Drug Administration (FDA) has reopened the period of public comment on proposed rule changes that would tighten controls on dental amalgam, a mercury-containing material used in dental fillings.

Dental amalgam is a silver-colored material consisting of about 50% liquid mercury by weight and 20% to 35% powdered silver, with the remainder comprising tin, copper, zinc, and other metals.

It is the mercury part that worries some patients and consumer health advocates, who point to the known neurotoxic properties of the element and question whether it can leach out of fillings and into the bloodstream.

In 2002, the FDA published a proposed rule that would classify amalgam as a "class II device with special controls," subject to labeling requirements, specific performance standards, and/or postmarket surveillance.

In April 2008, under pressure from consumer groups, the agency reopened the comment period for the proposed rule, inviting additional testimony backed by empirical data and scientific evidence on the relative safety or hazards of dental amalgam. The move was cited in a press release from the Institute for Progressive Medicine a self-described "revolutionary medical clinic that emphasizes safe, natural and alternative treatments in combination with traditional medical techniques" as evidence that the FDA is finally waking up to the "possible threat [of amalgam] to high risk population groups."

"The mercury in amalgam fillings is continually vaporized and released into the body," the press release stated. "This process is stimulated and can be increased as much as 15-fold by chewing, brushing or drinking hot liquids. The mercury released from amalgams is stored in the body and brain and accumulates over time. Additional mercury exposures from the diet and environment, contribute to the overall mercury body burden."

The group calls for blood or urine tests or hair analysis to detect mercury levels in the body, removal of amalgam fillings (except from pregnant women), and replacement of these fillings with composite (plastic) fillings, followed by oral chelation therapy to remove residual levels of mercury.

"FDA does not recommend that you have your amalgam fillings removed," said an FDA consumer advisory. "Dental amalgam fillings are very strong and durable, they last longer than most other types of fillings, and they are relatively inexpensive. You may want to weigh these advantages against the possibility that dental amalgam could pose a health risk, until further information is conveyed through the rulemaking or otherwise."

The FDA advisory panel found that there was not enough evidence to answer the question of whether amalgam is hazardous in young children or developing fetuses but noted that several countries, including Canada, France, and Sweden, have taken a precautionary approach, recommending avoidance of amalgam fillings in pregnant women.

Metal or Plastic?

A dentist who served as a consultant to the FDA Dental Products panel that considered the rule changes told Medscape that swapping amalgam fillings with composite fillings may be a case of replacing the devil you know with one you do not.

"There's never been any proof that the alternative restorations composites are equally safe," said B. Gail Demko, DMD, who has a private dental practice in Newton, Massachusetts. "No one has looked at long studies in vivo [to determine] how safe composites are."

Patients who require new or replacement fillings often ask for composites for aesthetic reasons or out of concern about the possible health risks of mercury-based amalgams, Dr. Demko noted. For their part, dentists have a financial incentive for offering composites, which are both more expensive than amalgam and last only about half as long.

"Plastic composites are typically not well finished, don't fit well, and are glued in place with composite glues, so really, what's keeping them in the mouth is plastic, and the plastic starts to leak and wear out within 5 to 10 years," Dr. Demko said.

"Silver amalgam is second only to gold for the material I would have in my mouth," she added.

The FDA has set a deadline of July 28, 2008, for additional comment on its proposed rule changes.
