Dental Amalgam Controversy

The dental amalgam controversy refers to the conflicting views over the use of amalgam as a filling material mainly because it contains the element mercury.

The concern centers on the health effects of toxicity or allergy which may be associated with constant mercury exposure, particularly as a potential cause of chronic illnesses, autoimmune disorders, neurodegenerative diseases, birth defects, oral lesions, and mental disorders.

Does your dentist use mercury amalgam? How many dentists do? The Wealthy Dentist says it’s almost 50-50! The survey said that 48% of the dentists surveyed said yes, they use Mercury Almagum fillings, 52% said they don’t.

Is it an issue and I wonder, does mercury amalgum really do damage?

Dr. John Whitman Ray N.D., M.D. (M.A.) believes it does.

Dr. Ray had the pleasure of testing several hundred patients and students in his field of Body Electronics with the Jerome Mercury Vapor Analyzer.

Dr. Ray found only two people in all of his testing who had not evidenced a continual toxic exposure to mercury vapor emanating from silver amalgam dental fillings under normal chewing compression.

Dr. Ray reports under normal chewing compression the amount of mercury vapor emitted exceeded in ten seconds more than the maximum allowable mercury exposure in a 40 hour work week as is indicated by both Russian and U.S.A. standards.

Dr. Ray goes on to say, “Dentists have been educated to believe that once mercury has been combined into the filling material, it remains “locked in” and can’t come out. The sad fact is that there is absolutely no scientific research in existence to support this hypothesis. To the contrary, all evidence indicates that silver amalgam containing approximately 50% mercury is a source of extremely toxic elemental mercury adversely affecting the health of the human body. ”

“Surface particles of the amalgam filling material,” Dr. Ray continues, “are being chemically broken down and released into the oral cavity as evidence shows. These minute particles of mercury filling are acted upon by oral and intestinal bacteria to produce methyl mercury, an even more toxic form of mercury than elemental mercury with target areas being primarily the pituitary gland, thyroid gland, and the brain.”

As if to prove what Dr. Ray said, Stephen Barrett, M.D. explains that mercury when mixed with the other elements, bond to form a strong, stable substance.

Dr. Barrett explains that the difference between bound and unbound chemicals can be illustrated by a simple analogy. Dr. Ray says, “Elemental hydrogen is an explosive gas. Elemental oxygen is a gas that supports combustion. When combined, however, they form water, which has neither of these effects. Amalgam’s ingredients are tightly bonded to each other. Although the types of chemical bonds in water and amalgam differ, saying that amalgam will poison you is just as wrong as saying that drinking water will make you explode and burst into flames.”

Scientists agree that dental amalgam fillings leach mercury into the mouth, but studies vary widely in the amount and whether such amount presents significant health risks. The effects of that amount of exposure is also disputed, and currently dental amalgam is approved for use in most countries, although Norway, Denmark and Sweden are notable exceptions.

Dentists who advocate the use of amalgam point out that it is durable, cheap, and easy to use. On average, it is said, that resin composites last only half as long as dental amalgam, but Dr. Hronkin has found composites that work as well or better than mercury amalgam.

Material that is now available is as strong or stronger than the amalgam material yet further concerns have been raised about the resin composite reacting with endocrine disrupting in particular, estrogen-mimicking effects of plastic chemicals such as Bisphenol A used in composite resins.

For Dentists who think that the best choice is the composite resin Mercury Free Now shares the protocol for safely removing mercury fillings.

An important aspect of the protocol is the use of a rubber dam. A rubber dam isolates the tooth or teeth being worked on.

Some mercury free dentists don’t believe this is absolutely necessary, but it’s Dr. Hronkin’s opinion that it can reduce the amount of mercury vapor inhaled through the mouth. Click here to read more of the protocol.

In this Information Era we have access to do the research ourselves. We can work with our health care providers and make informed decisions about our treatment.

Unfortunately, no matter how much information we have, reality is there are some things that no matter what we do, we can’t change.

No matter, I’ll continue to do my best to make a positive difference in my health and in my life.

  1. Hi Linda – My dentist removed all of mine a few years back. He just said they were wearing down and the new ones would look a lot better because they are white. After reading this – Now I am thinking maybe there were other reasons. Thanks for this info.

    • Glyna,
      Were you nervous about the mercury causing you problems when they were replaced? I have a friend who cautioned me STRONGLY about choosing a Dr. who knew how to properly remove them. I hadn’t even been worried until Roxanne shared her concerns.


  2. Hi Linda,
    I would love to have mine changed, but the process is so expensive here in Finland that I haven’t been able to do that yet. I have been told years ago that amalgam in fact really is dangerous to the health and should not be used. The problem is that that’s what all the dentist in Finland used when I was young and got mine. During the years luckily part of them have been changed due to wearing out.I certainly have some issues I believe are due to mercury in my body (my “liver points” everywhere are always tender, I have headaches etc. Of course they can be explained with a lot of things but over the years I have been able to “listen” to myself).
    I wish that some day I will be able to get all the rest of them off !

  3. Hey Linda,

    This is my second visit to your blog and I enjoyed it just as much as my first. Very educational and at the same time entertaining … was happy to accompany you in the dentist’s chair!

    Mercury amalgam is very much frowned upon in Ontario so most Dentists in this area do not use mercury in their practice.

    Once again thanks for sharing your personal stories and experiences with me and all of your readers. I look forward to our next adventure.


    • Kevin,
      Thanks for saying so! I really get a kick out of sharing them with everyone! Just like I said, I really have no idea if removing the mercury is going to help me, and I won’t know for a couple years. I wish money weren’t a limiting factor! If I knew for a fact that it would help, I wouldn’t wait for the insurance. Since I don’t know, I’ll wait for a least partial payment!

  4. Hi there Linda, i followed you advice from your email a couple of days back and decided to take another look at your new content!
    Its such a shame for you, and all of us for that price is a determening factor, dental care is so expensive!


  5. Michael,
    I have to agree with you! Money is often a limiting factor! Removing mercury is very expensive dental work!

  6. Hi Linda – I’ve been reading about the dangers of amalgam fillings for a few years now – would love to have mine removed – as far as I know I am not suffering any deleterious effects – but anything we can do to remove risk and live healthier is worth looking into. Thanks for such an informative post! Lori

    • Hey Lori~
      It seems obvious to me too yet money is often a limiting factor! Then the controversy comes in when people start to think about where all the mercury goes when it’s taken out of so many mouths? Will it end up in the water system? It’s all curious!
      Thank you for reading my blog!

  7. Hello Linda
    Linda, this statement is so important “In this Information Era we have access to do the research ourselves. We can work with our health care providers and make informed decisions about our treatment.” I recently was told that I had to take a statin drug. Doing exactly what your statement says did research on the drug found it was not for me and then looked for alternatives. Finding a solution and discussing with my Dr, the situation was corrected without the statin .

    Your blog is very educational.

    • Perry,
      I’m glad this advice helped you! I have always loved to give advice, I just wish I never had to learn about life with MS well enough to give advice!

  8. Hi Linda,
    I worked with a biological dentist in London, UK as a Bio-Energetic Medicine practitioner and many of my clients had been diagnosed with MS. this is a subject very dear to my heart. I would love to connect with you further. I now live in Seattle, WA. I will message you on Facebook. Wish I had visited your site a long time but I was bereaved earlier this year ( husband had Lou Gehrig’s disease) so my life was upside down since I have three young children to care for and to provide for!!!

  9. Mercury is a deadly poison period. The concentration used in fillings might be negligible, but that’s a big risk to play with your health. Years later, developing a myriad of conditions just because you had a bad tooth/teeth that needed to be filled.

  10. The material, in my opinion, desiccates (dries out) teeth making them more brittle and prone to cracks and fractures. Several times every month, I see patients who suffer from broken teeth that have dental amalgam restorations.

    Great share Linda 🙂

    • It’s funny that you say that! Last week one of my teeth scheduled to have the amalgam removed in Jan when a new insurance cycle begins, chipped! I hope I can hang out 4 months~ money is often a limiting factor!

  11. Thanks Linda for this useful article. I think anything that have a slight chance to produce mercury is very dangerous to our health and so it would be better for ourselves to stay away from this kind of treatment.

  12. Mercury itself is a very dangerous metal and when it’s about your dental health it is better to be avoid mercury amalgum. Because their will be a chance remain that it will cause some irritation in your mouth.

  13. Wow! I never even heard of this stuff. We wouldn’t use something with Mercury in it anyways. Sounds too dangerous.

  14. “Dental amalgams contain mercury, which may have neurotoxic effects on the nervous systems of developing children and fetuses. That means a person carrying a baby will transfer mercury to their unborn child.

  15. I think the information Era we have access to do the research ourselves. We can work with our health care providers and make informed decisions about our treatment..Thanks!

    • Yes Johanfrancho!
      We really need to take responsibility for our health care! with such wonderful access we have online, all we need is a computer and the internet~ I say that as I type very weakly do to the MS! So I guess I need to add Health to the list of what we need!

  16. Before doing so, You must seek first an advise of the experts or most desirable your dentist. Because as well know money would be such an important thing. And I could say, you don’t want to waste your money with low quality, right? There should be a lot of process before decision making occurs.

    • Nathan,
      I don’t know how I missed your comment months ago! Yes, we have to be so careful with how the amalgam is removed! It could cause more harm than good!

  17. Hi,
    This was a very great and interesting article to read. Mercury is a metal which is very toxic and poisonous. It just reaches to each and every cell of our body and make our immunity system weak. So everybody should be very careful in taking the decision of amalgam.


  18. That is very interesting, You’re an excessively professional blogger. I have joined your rss feed and look ahead to searching for more of your magnificent post. Additionally, I have shared your web site in my social networks

  19. I tend not to write a great deal of comments, but i
    did a few searching and wound up here Dental Amalgam Controversy —
    And I actually do have some questions for you if you tend not to mind.
    Could it be just me or does it give the impression like a few
    of these responses look like left by brain dead visitors?
    😛 And, if you are writing at additional social sites,
    I would like to follow anything new you have to post. Could you make
    a list of all of your shared pages like your twitter feed, Facebook page
    or linkedin profile?

    • Hey Olga~
      Yes, I think that some comments are written without reading the post first! Our connection buttons are to the right~ I’d love to see more of you!
