Still Carrying Around This Potent Neurotoxin Next to Your Brain?

Still Carrying Around This Potent Neurotoxin Next to Your Brain - Mercury Amalgam Fillings

By Dr. Joseph Mercola

Guest Writer for Wake Up World

Dental amalgam, a.k.a “silver fillings” contain anywhere from 49 to 54 percent mercury.

Toxic mercury vapors from “silver fillings” are released into your oral cavity every time you chew or drink hot liquids. A single dental amalgam filling releases up to 15 micrograms of mercury per day — over six times the amount you’d get from eating mercury-contaminated seafood — and is the primary source of mercury exposure in consumers.

Mercury is a neurotoxin that readily crosses your blood-brain barrier, cellular membranes, and your central nervous system. It is known to cause psychological, neurological and immunological health problems.

This below eye-opening video from the International Academy of Oral Medicine and Toxicology ( is worth more than a thousand words when it comes to illustrating the very real danger of mercury fillings. It contains a powerful visual demonstration of how mercury vapors are released into your oral cavity every time you chew, visit the dentist, or drink hot tea or coffee, for example.

And these mercury vapors continue to be released for at least 1.5 hours after each stimulation.

The poisonous vapors are odorless, colorless and tasteless, so you can’t tell when it’s happening. But you can be sure that if you have so-called “silver fillings” in your mouth, you’re continuously exposed to mercury, which passes readily through cell membranes, across the blood-brain barrier, and into your central nervous system, where it can cause psychological, neurological, and immunological problems.

Amalgams = The Number One Source of Mercury Exposure

Dental amalgams are the primary source of mercury exposure in Americans. A single dental amalgam filling releases as much as 15 micrograms of mercury per day. The average individual has eight amalgam fillings and could absorb up to 120 micrograms of mercury per day. For comparison, eating mercury-tainted seafood will expose you to about 2.3 micrograms per day — and that is enough for scientists to call for a worldwide warning!

Unfortunately, while many have become well aware of the dangers of environmental mercury contamination, few are as well-informed when it comes to the dangers posed by dental amalgams.

Sadly, only one in four people is aware that silver amalgams contain mercury, and the dental industry is capitalizing on that ignorance. Part of the problem is that the very name “silver fillings” seems to imply they are made of silver, a misdirection that has kept a good majority of consumers in the dark for a long time. Alas, amalgams consist of more than50 percent mercury. When confronted about this, the industry response is that the term “silver” is meant to denote the color, not the constitution…

However, dentists have also been actively persuaded to keep this information under tight wraps, and they are under no obligation whatsoever to inform their patients about the mercury content of amalgam fillings. As recently as 2009, the FDA ruled that no warning shall be issued to patients — not even to young women and parents of young children — even though the mercury from the amalgam fillings is a reproductive toxin and a neurotoxin, and despite the fact that pregnant women and young children are at greatest risk from mercury toxicity.

An Antiquated and Hazardous Dental Tool

In the words of Charlie Brown, president of the World Alliance for Mercury-Free Dentistry,

“Amalgam is a primitive, polluting, 19th century product that began when physicians were sawing off legs. Medicine has since moved forward.”

Unfortunately, this aspect of dentistry has not. The American Dental Association (ADA) continues to give amalgam (mercury) fillings their seal of approval, stating:

“Used by dentists for more than a century, dental amalgam is the most thoroughly researched and tested restorative material among all those in use. It is durable, easy to use, highly resistant to wear and relatively inexpensive in comparison to other materials. For those reasons, it remains a valued treatment option for dentists and their patients.”

The height of irony is that dental amalgam is shipped as a hazardous material to the dental office, and any amalgam leftover is also treated as hazardous and requires special precautions to dispose of. Yet, most dentists will readily implant this hazardous material directly into your mouth, with assurances that it’s perfectly safe and harmless!

The Health Hazards of Mercury Fillings

Mercury is a potent neurotoxin that can damage your brain, central nervous system and kidneys, and mixing it with other alloys and placing it in your mouth does NOT all of a sudden render it harmless… Children and fetuses whose brains are still developing are at greatest risk, but anyone can be affected. Naturally, the more amalgams you have, the greater your risk of experiencing health problems as a result.

In the above featured video, they show that:

  • When amalgam was placed in sheep, substantial quantities of mercury spread from the filling and accumulated in the animal’s jaw, liver, kidney and stomach after just 30 days.
  • The sheep’s kidneys also dropped the ability to clear inulin by 60 percent—an indication of kidney malfunction.
  • Antibiotic-resistant dystrophic bacteria was discovered in the primates’ intestinal flora, within just two weeks of receiving mercury fillings.
  • Mercury fillings damage the ADP-ribosilation of brain neuronal proteins.
  • When amalgam fillings were placed in pregnant sheep, mercury was immediately transferred to the placenta and every part of the fetus. After birth, the offspring’s mercury levels continued to rise as a result of ingesting the mother’s milk.

Mercury is especially damaging to your central nervous system (CNS), and studies show that mercury in the CNS causes psychological, neurological, and immunological problems including:

  • Arrhythmias and cardiomyopathies
  • Tremors
  • Insomnia
  • Weakness
  • Personality changes and irritability
  • Headaches
  • Blurred vision
  • Slowed mental response
  • Unsteady gait

To make matters worse, mercury bonds very firmly to structures in your central nervous system. Unless actively removed, mercury has an extremely long half-life of somewhere between 15 and 30 years!

BEWARE! Amalgams Must Be Removed PROPERLY

It should be clear that there’s simply no such thing as a safe mercury filling. However, please do NOT make the mistake of having your amalgam fillings removed by a dentist who is not properly trained in safe amalgam removal. Doing so could expose you to tremendous health risks, due to the large amounts of mercury vapor being released during the removal process.

Research has shown that if you do not take proper safety precautions during the removal process, mercury levels in your blood can rise three to four-fold, which may result in acute toxicity.


Make sure to use a so-called biological dentist that is trained in properly removing mercury fillings. Some things that need to be done to keep you (and your dentist) safe during the procedure include:

  • Providing you with an alternative air source and instructing you not to breathe through your mouth
  • Using a cold-water spray to minimize mercury vapors
  • Putting a rubber dam in your mouth so you don’t swallow or inhale any toxins
  • Using a high-volume evacuator near the tooth at all times to evacuate the mercury vapor
  • Washing your mouth out immediately after the fillings have been removed (the dentist should also change gloves after the removal)
  • Immediately cleaning your protective wear and face once the fillings are removed
  • Using room air purifiers

For a complete description of how to safely remove mercury amalgam, see this PDF created by the International Academy of Oral Medicine and Toxicology (IAOMT). The proper procedure is also explained in the featured video.

Here are several sources to help you locate a dentist trained in biological dentistry:

Avoid making the same mistake I did 20 years ago when I had all my amalgams removed by a competent dentist who was an elder at the church I attended. Unfortunately, he was clueless about mercury toxicity and used no precautions and as result I got kidney damage. Additionally, I had to remove all the crowns he put in because they were metal. It was a very expensive and health damaging mistake.

I also suggest you get healthy BEFORE having your fillings removed, as you want your detoxification mechanisms optimized prior to removal. To remove mercury that has already accumulated in your body, I highly recommend reviewing my Mercury Detoxification Protocol, which details the things you can do right now to help rid your body of this toxin. If your mercury levels are seriously elevated, you should work with a knowledgeable health care practitioner to help you through the detoxification process.

    Every one need to contribute their two cents in frighting the Global War on Toxins.
    Toxins in thoughts translate to toxins in food, medicine, water, air, environment, Wall Street, Fer. Res.
    With toxin galore there simply is no lack of crooks to participate. Goldman Sachs, MONSANTO, Pfizer, mere creation of the toxic thoughts and environment created by toxic (morbid) minds.

        Hi! Thank you for the article! It would be very appreciated if you could let me know where I can get this done (remove the mercury fillings) in The Netherlands? Thank you!
        I’ll spread the word around here, hopefully people will listen.

  • Elfreda

    The information on this site is beneficial.

  • Denise Mansell

    Having the same question. I live in B.C. Canada. Are ther any in Kelowna or Vancouver? None are advertised in my searches… Thanks!

    I have a degenerative nerve disease and can’t help but wonder. My teeth were FULL of these by the time I was 8, and I am now 50 ‘sigh’.

  • Oxidizer

    I have at least 5 fillings in my mouth and I’m still young… Thanks for the article, now I know they don’t only look ugly. I really should do something about this.

  • Oxidizer

    My bad, I didn’t even know mercury fillings had been replaced by others. (My common knowledge is awful if I have any.) So now what is left is just to avoid eating mercury-contaminated seafood and not to break thermometers with mercury, I suppose.

  • Nick

    I just checked out the common symptoms and effects of mercury poisoning! I would not be surprised if mercury is found to have a strong link, or be the cause, of the massive increase in Dementia and Parkinson’s in our society!
    Does anyone know if there are any studies being conducted into this area?

  • Hisako Carmack

    I do not really understand how there is much different between the New York Times printing this or some internet blog. Stuff such as this needs to be pushed out more frequently. I wished that someone else in America would stand up for peoples rights like this.

  • Emery Parlin

    I dugg some of you post as I cerebrated they were very beneficial extremely helpful

  • So it would have been nice to provide a little more detailed information. For instance, when did they phase this type of filling out? Are they still being administered at all? What about in third world countries? Is there a way to tell if the fillings I have are this type? If these are no longer being administered today, then what is? Is there more than one option today? What are the different options and is there anyway to tell which type we have?

    I had a couple fillings as a kid, and have carried them around for the better part of around 30 years. I recently had them drilled out and refilled because deeper decay under and around them. I’m sure the dentist took none of the precautions you talked about. I’m in China. The new fillings were a white paste which was dried with some kind of ultraviolet light (not certain it was UV, but some sort of light). They are white now so I am assuming it is something better than the old ‘silver’ fillings?


    If at all possible, have a bio-combatibility test done before you replace the amalgam with composite fillings. This will help prevent replacing one bad situation with another. Also, keep in mind that the “white” fillings often contain BPA or its derivatives. Teeth actually have the ability to repair and regenerate when cared for properly, sometimes even pushing out old fillings in the process. A great book is “Cure Tooth Decay” by Ramiel Nagel.

    Hey guys.. Just want to let everybody know that I had a filling removed last summer.. I only had one but I think my whole perspective on life slowly has developed to a more naturalistic one.. This of course both has positive and negative consequences when for instance sometimes being natural is not appreciated by the environment one might find oneself in.. My father and mother have fillings and I told them to get them out but they dont really think its important.. I think their fillings has stopped their spiritual/intellectual/natural development of their minds and therefore life in general.. Especially my father who has a lot and has had them for a long time..
    I would encourage and advise everyone to get these out if you can save enough money to get it done properly.. Clearly doing it wrongly can be directly lethal if you ingest some parts of the crumblings.. I finally feel natural in my body and mind.. My hormones has been inhibited at the time of my puberty which can be seen in the physique.. I am tall but have small hands, feet and penis.. And generally my body doesnt put on fat or more muscle mass..
    This disturbance of my development could very well be due to mercury which is a really really strong energetic disturbance that can penetrate a lot of places in our organisms..
    I think a lot of people have hormorne desturbances and have developed less naturally.. If we go back one thousand years I think we were all generally good looking and with great physiques.. Of course some genes code for smaller humans and so on but right now, we are totally messed up, haha.. Maybe we can fix this in the future but we have to fix our broken system of economics first and get our food and water supplies running in full capacity, environmentally friendly = naturally, without all kinds of crappy human made substances..
    Anonymo power!

    So..I have many of these and actually prefer them because they stay in better than the white ones…but what options are there outside of the white and mercury filled ones!? I wish I knew before all this that teeth can heal. My “cavaties” never bothered me. It was only because of the x-rays I ever even knew.
