Silver Amalgam Use Now the Focus of a United Nations Treaty

Silver Amalgam Use Now the Focus of a United Nations TreatyFoxNews.com is reporting that a United Nations global mercury treaty on mercury pollution may become reality and America’s dentists could be subjected to an international ban on filling cavities with “silver amalgam” containing mercury.

The next round of “mercury talks” is scheduled for Monday in Kenya and State Department officials reportedly said they hope to garner support for a legally-binding treaty to reduce worldwide mercury emissions.

Dr. David Simone, a dental surgeon from Northbrook, Ill., who attended the State Department meeting, told FoxNews.com that State Department officials reiterated that amalgam fillings will likely remain on the U.N.’s designated list of products to eventually be phased down with passage of the so-called global mercury treaty.

There is a controversial ongoing argument among dental health professionals about the possible health risks associated with mercury exposure from amalgam fillings, and competing sides disagree on whether the amount of mercury in fillings causes risks.

The ADA supports the position that dental amalgam is safe and posts the following statement on its website –

Dental amalgam is considered a safe, affordable and durable material that has been used to restore the teeth of more than 100 million Americans. It contains a mixture of metals such as silver, copper and tin, in addition to mercury, which binds these components into a hard, stable and safe substance. Dental amalgam has been studied and reviewed extensively, and has established a record of safety and effectiveness.

The FDI World Dental Federation and the World Health Organization concluded in a 1997 consensus statement: “No controlled studies have been published demonstrating systemic adverse effects from amalgam restorations.” Another conclusion of the report stated that, aside from rare instances of local side effects of allergic reactions, “the small amount of mercury released from amalgam restorations, especially during placement and removal, has not been shown to cause any … adverse health effects.”

In 1998 the ADA’s Council on Scientific Affairs published its first major review of the scientific literature on dental amalgam which concluded that “based on available scientific information, amalgam continues to be a safe and effective restorative material.” The Council’s report also stated, “There currently appears to be no justification for discontinuing the use of dental amalgam.”

In an article published in the February 1999 issue of the Journal of the American Dental Association, researchers report finding “no significant association of Alzheimer’s Disease with the number, surface area or history of having dental amalgam restorations” and “no statistically significant differences in brain mercury levels between subjects with Alzheimer’s Disease and control subjects.”

A 2003 paper published in the New England Journal of Medicine states, “Patients who have questions about the potential relation between mercury and degenerative diseases can be assured that the available evidence shows no connection.” [Read more …]

Robert Ferguson, founder and president of the Science and Public Policy Institute (SPPI), told Foxnews.com that he sees the controversy surrounding dental amalgam as little more than the latest scare to drive more regulation.

Dentists Not Concerned About Chemicals Used in Dentistry

Dentists Not Concerned About Chemicals Used in Dentistry“Not particularly worried” is the most popular response for concerns about the chemicals in dentistry among dentists, according to a new The Wealthy Dentist survey, but the results are pretty evenly split.

The online survey asked dentists from the U.S. and Canada if they are concerned about the safety of dental composite and sealants.

54% were not worried, while 46% had concerns about safety.

Here’s how the dentists responded —

  • 21% – Definitely yes! I am very concerned about this issue.
  • 25% – Somewhat. I have some worries about safety.
  • 38% – Not really. I’m interested, but not particularly worried.
  • 16% – Definitely not! I’m not worried at all.

Chemicals Used in Dentistry Survey Results Graph

“It’s about the same argument as the amalgam and mercury issue. I don’t see that the literature to date points in any direction toward concern about BPA!” a Mississippi dentist said.

BPA in tooth fillings has been in the news recently due to a study linking the chemical to behavioral problems in children.

According to Dr. John Reitz of Reading Eagle Press, “When dental manufacturers became aware of the health risk of BPA they made a conscious effort at eliminating or at least limiting the amount in dental products. According to research by the American Dental Association, BPA is rarely used today as an ingredient in dental products.”

Most of the dentists who responded to this survey agree that there are minimal risks from dental chemicals.

Here’s what many dentists had to say on the subject —

“We need more long-term studies.” (New Jersey dentist)

“To temper this, we have to remember that ANYTHING in the body outside of what is indigenous is considered foreign and has potential to elicit yet another of those unexpected side effects, sort of like most of Congress’ laws. Since I stopped doing sealants years and years ago, I am less concerned about the effect on most adults.” (General dentist)

“Amalgam is on its way out. Let the chemist reformulate BPA-free dental products!” (Alabama dentist)

“I didn’t know that I need to be concerned…” (California dentist)

“No patients have shown any worry. I do feel extensive research should be conducted.” (Mississippi dentist)

“Yes – patients ask about it! But I understand there are different kinds…some more damaging than others.” (Michigan dentist)

“I’ve never had a patient even mention it, unlike the ‘wackos’ who won’t let fluoride touch their kids lips…” (General dentist)

“None of our patients have mentioned it, yet. But, I won’t be surprised if or when they do in the future. I’m personally concerned about BPA in composites. I certainly didn’t want it in the plastic baby bottles my child used, so why would I want it in composite resin dental restorations? Dentistry certainly needs to have BPA free restorative materials.” (Ohio dentist)

“Parents are now asking me about our materials and if they contain BPAs.” (Pediatric dentist)

The ADA Council on Scientific Affairs has not identified evidence to suggest that the use of resin-based dental sealants or composite resin restorative materials is linked to adverse health effects from BPA exposure. (Source: ADA)
