Dentists Say Lead Is Dentistry’s Biggest Health Threat

Other Dental Health Concerns Include Mercury and Bisphenol-A

In this survey, we asked dentists how concerned they are about various potential public health threats linked to dentistry. Dentists’ concerns, in order, are:

General dentists versus specialists

Lead in dental lab work
Mercury in amalgam
Bisphenol-A in composite, and
Fluoride in water supplies.

General dentists had higher levels of concern on all issues than specialists. However, specialists and generalists agreed on the relative dangers of the chemicals covered in this survey.

Dentists’ thoughts

“I’d like to be doing all gold restorations.” (New Jersey dentist)
“All four of these need to be totally nailed down as to their safety, or lack thereof.” (Arkansas dentist)
“Two things that will bite dentistry in the butt are fluoride and amalgam if we don’t stop forcing them on the public.” (Idaho dentist)

Mercury

“150 years have not proved Amalgam to be dangerous.” (Arkansas dentist)
“Amalgams have saved billions of teeth!” (Washington dentist)
“A known toxin, no safe levels, should be banned.” (Louisiana dentist)

Lead

“Lead in dental casting alloy? Outrageous!” (Colorado dentist)
“Recent articles have debunked the worry over the amount of lead in ‘farmed-out’ crowns. Still, we need to monitor that work.” (California dentist)

Bisphenol-A (BPA)

“This stuff is everywhere. Composites without BPA just don’t hold up well.” (Wisconsin dentist)
“It’s probably not too dangerous, but don’t cast stones, Mr. Composite: you live in a glass house!” (New Jersey dentist)
“It’s ironic that many patients are removing long tested amalgam and replacing them with bisphenol composites of unproven safety.” (California dentist)

Fluoride

“It’s been shown to be effective, but we shouldn’t be medicating the whole population.” (Colorado dentist)
“The best public health measure ever instituted in this country for caries prevention.” (Texas dentist)
“Known to be toxic.” (California dentist)

FDA Finally Takes a Stand on Mercury… Sort Of

October 22, 2019 By Jim Du Molin Leave a Comment

Agency Promises to Make a Decision Next Year

The Food and Drug Administration (FDA) has long avoided taking a public stand on the safety or danger of mercury in silver dental fillings. However, with a recent settlement in a lawsuit brought by the organization Moms Against Mercury, the governmental health agency has finally agreed to take a stand on the issue. Eventually.

The agreement calls for the FDA to complete its reclassification of dental amalgam by July of 2009. (The agency began that process in 2002.)

Some news articles have heralded this as a major change in the FDA’s attitude toward amalgam, with headlines making grand proclamations about a new post-amalgam era.

Can you guess which of the following is not a genuine headline?

These are attention-grabbing headlines, to be sure! The problem is, they’re not necessarily true per se. (And okay, I made the last one up.)

In the ADA’s response to news of the decision, the dental organization disputes these suggestions. “As far as the ADA is aware, the FDA has in no way changed its approach to, or position on, dental amalgam,” reads the statement.

As part of the agreement, the FDA has updated the consumer information provided by its website on the subject of mercury and dental amalgam.

“Dental amalgams contain mercury, which may have neurotoxic effects on the nervous systems of developing children and fetuses. When amalgam fillings are placed in teeth or removed from teeth, they release mercury vapor. Mercury vapor is also released during chewing. FDA’s rulemaking will examine evidence concerning whether release of mercury vapor can cause health problems, including neurological disorders, in children and fetuses.”

What do you think? Is this a new era, or just more of the same?

Dentists Passionately Love and Hate Dental Amalgam (Video)

Dentists have used dental amalgam to make metal fillings for a long time, but the material is more controversial now than ever before.

Some worry the silver/mercury alloy may cause health problems, while others think it’s still superior to tooth-colored composite fillings.

Dentists Split Over Amalgam Fillings (VIDEO)

Dentists are deeply divided over the issue of mercury in amalgam fillings. In this survey, 52% of dentists reported they are no longer using amalgam. The other 48% are still placing amalgam fillings.

Some dentists criticized amalgam for its possible toxicity and tendency to fracture teeth; other dentists defended amalgam’s long history and superiority to more modern composite fillings.

Mercury Safety Is Different from Amalgam Safety

October 22, 2019 By Jim Du Molin

Mercury safe dentistry seems like a good idea for everyone, so I wasn’t expecting so much controversy from Dr. Tom McGuire’s article on the topic (read the article). Though dentists have lots to say about the consumer safety of amalgam fillings, that’s not what we’re talking about here.

We’re just talking about protecting dentists, staff and patients from mercury exposure during amalgam removals. Doesn’t that seem like something everyone can agree is important, regardless of whether one is pro-or anti-amalgam?

I’d like to address some of the points readers raised about Dr. McGuire’s article.

“Since when is anyone who wants to promote his moneymaking ‘seminar’ considered to be ‘a leading authority?’On what grounds?Is he an established professor at an accredited dental school? In which department? Sheesh, if I call myself an ‘expert toxicologist’ six times before lunch, does that make me one?”
– Bill C., DDS

I think it’s safe to call someone “a leading authority” when they’re authored multiple books on the subject and founded a professional association, like Tom McGuire, DDS, founder of the International Association of Mercury Free & Mercury Safe Dentists (IAMFD).

I understand you may disagree with some of Dr. McGuire’s opinions. But the fact of the matter is, he’s a heavy-hitter in amalgam debate.

As for his seminars…

“Since all of the uproar about Dr. McGuire’s article I decided to visit the seminar website. I didn’t see anything about arguing that amalgams are a health hazard. All I got was that dentistry is a high risk occupation because of mercury and that it would be prudent, for many reasons, to deal with the occupational exposure to it. I really don’t see this about being pro or anti-amalgam and I still think everyone is entitled to his/her opinion about that topic. What I read was that it is about being anti-mercury and finding out what you can do to protect yourself. After looking at the website I’m going to attend his seminar, and it is a 2 hour flight for me.”
– Bob B., DDS

Where Bill sees a chance to lose money, Bob sees a chance to gain important education. Either choice is fine. The Wealthy Dentist isn’t endorsing Dr. McGuire’s views, just giving him a chance to share his knowledge.

“Odd how the studies seem to prove whatever it is you want them to show.”
– Dr. Gary Hochstetler

An excellent point. When both sides of the consumer amalgam debate claim the science is clearly on their side, it’s hard to know who to believe.

That’s why we’re trying to move the debate away from if having amalgam fillings is safe and towards how much mercury exposure dental health professionals face.
