EU kieltää amalgaamipaikat - Metyylielohopea (Methylmercury) liukenee hammaspaikoista vereen




Metyylielohopea on elohopeametallin orgaaninen, ihmiselle vaarallinen muoto. Sen molekyylikaava on CH3Hg+.Ihminen saa kehoonsa elohopeaa ravinnosta, sekä hampaiden amalgaamipaikoista.


Euroopassa elintarvikkeiden ja juomaveden sisältämälle elohopealle on säädetty tarkat raja-arvot. Siitä huolimatta elohopeaa on mm. rokotteissa. 


Pitkäaikainen elohopealle altistuminen johtaa munuais- ja aivosairauksiin. Syy-yhteyttä on kuitenkin usein vaikea todentaa, sillä neurotoksinen elohopea on kumuloituva myrkky, joka kerääntyy elimistöön pitkällä aikavälillä.  Amalgaamipaikkojen sisältämä elohopea höyrystyy suussa ja siirtyy elimistöön limakalvojen kautta.



Elimistöön joutunut metyylielohopea pääsee rasvaliukoisena aineena helposti hermostoon.
Elohopeamyrkytyksen oireisiin[1] kuuluvat tunto- ja näköhäiriöt, ataksia, käsien ja jalkojen puutuminenlihasheikkous, supistunut näkökenttäkuulovaurio ja puhehäiriö.


Vaikeissa tapauksissa myrkytysoireet jäävät pysyviksi ja äärimmäisissä altistuksissa, kuten Minamatan syndroomassa oireisiin lukeutuvat psykiatrisetoireet, halvauskooma ja kuolema, jotka seuraavat viikoissa ensimmäisten oireiden esiinnyttyä.
Kaikkein herkimmin vaikutukset kohdistuvat kehittyvään sikiöön. Tulokset normaalista ravinnosta saatavan metyylielohopean vaikutuksista ovat toistaiseksi ristiriitaisia, koska kahdessa erittäin paljon kalaa käyttävässä väestössä on saatu erilainen tulos, Färsaarilla on nähty lievän hermoston kehityksen hidastumisen liittyvän suureen metyylielohopeapitoisuuteen mutta Seychelleillä ei. Suomessa on kuitenkin suositeltu, ettei raskaana olevien tulisi käyttää haukea lainkaan.[2]
Metyylielohopean on havaittu aiheuttavan iibislinnuilla "homoseksuaalista" käytöstä, jossa uroslinnut asettuvat yhteen toistensa kanssa.[3]

Mercury fillings face Europe-wide ban in 
Dentists across Europe will stop using amalgam fillings—which contain mercury—in pregnant and nursing women and children under the age of 15 in 2018. The ban, which affects dentists in all the 28 member-countries of the EU, comes into effect in July next year.

The ban needs to be officially ratified, but this is expected to be a formality as the European Commission, the European Council and the European Parliament have already agreed to it. 

Health agencies in each of the member countries must also submit plans as to how they will be reducing the use of amalgam fillings in the rest of the population by 2019.
The edict is a triumph for consumer groups who have played a major role in the six-year consultation period—and a blow to the dental associations that still maintain that amalgam fillings are safe.Groups such as the World Alliance for Mercury-Free Dentistry predict the ruling marks the beginning of the end for amalgam fillings across the developed world.
Amalgam fillings—which are a mix of silver, tin and copper in liquid, or elemental, mercury—have been used by dentists for more than 150 years because the material is inexpensive and pliable.

Dental associations have maintained the mercury—which makes up around half the filling—is locked in, and can’t escape.
But, as WDDTY revealed last month (http://www.wddty.com/magazine/2016/december/the-secret-life-of-your-fillings.html) the mercury does escape, and can damage our brain, heart, kidneys, lungs and immune system—because our gut converts the elemental mercury into methyl mercury, its most lethal form.

The secret life of your fillings 

December 2016 (Vol. 27 Issue 9)  The secret life of your fillings  in 


For more than 150 years, dentists have been putting ‘silver’ fillings—or dental amalgam, which contains mercury—into cavities in our teeth. And for most of that time, dental groups have been reassuring us that the fillings are safe. The mercury is ‘locked’ within the material and can’t escape and, in any case, is elemental, or inorganic, mercury, the safest form of what everyone acknowledges is one of the most toxic metals on the planet.

But a major new study says our health guardians are wrong: mercury does leak from fillings, and it’s a substance that can damage our brain, heart, kidneys, lungs and immune system. And perhaps the most chilling part of the researchers’ discovery is that when the elemental mercury leaks into the bloodstream, the gut converts it into methyl mercury, its most toxic form.1

It’s a significant finding. Methyl mercury mainly comes from fish, and defenders of amalgam fillings have maintained that they weren’t adding to our overall ‘mercury load’. But the new discovery means that anyone with eight amalgam fillings will have 150 per cent more methyl mercury in their blood than someone without these fillings—and around 25 per cent of the American public has 11 or more silver fillings.

The open secret

It’s long been an open secret in dentistry

The American and British Dental Associations have barred dentists from putting up posters or handing out information sheets that reveal that
amalgam fillings are 50 per cent mercury, although dentists have been quietly moving towards the use of safer materials.
Despite such an information blackout, fears about the dangers of amalgam fillings began to escalate in the 1980s, when it was discovered they were releasing mercury vapours that were being deposited in the kidneys. Even then, the dental associations batted back the concerns because the evidence was inconsistent or based on only small study populations. 

Methylmercury 3D model 
But this new study, carried out by researchers at the University of Georgia, puts paid to those objections. They analyzed the data from 14,703 people gleaned from two previous US National Health and Nutrition Examination Surveys (NHANES), and compared the amount of mercury in the blood with the number of fillings each participant had. The researchers also considered other factors that contribute to mercury levels in our bodies, including the environment and the amount of fish in the diet.


After factoring in these other sources, the researchers still found a direct association between the number of amalgam fillings and amount of methyl mercury in the blood.
But while methyl mercury levels increased between the two surveys (2003–2004 and 2011–2012), there was no increase in the number of fillings. This suggests that the gut may be changing elemental mercury to methyl, said researcher and professor of environmental health science Xiaozhong Yu. “As toxicologists, we know that mercury is poison, but it all depends on the dose. So, if you have one dental filling, then perhaps that’s OK. But if you have more than eight dental fillings, the potential risk for adverse effect is higher,” he said.
The average American has three fillings, the researchers say, but even this may not be safe if they’re also eating fish more than a few times a week or are exposed to mercury in their work environment.
It stays with us
It could also be that amalgam fillings on their own can leak enough to cause unacceptably high levels of methyl mercury in the blood. The European Commission’s BIO Intelligence Service (BIS) evidently thinks so. A 2012 report pointed out that autopsies have shown that bodies with amalgam fillings can have up to 12 times more mercury than usual in their tissues.2
The World Health Organization (WHO) also believes that amalgam fillings are the most significant source of mercury in our bodies. It reckons we get four times the level of mercury from our fillings as from fish: if we are absorbing 10 mcg of mercury from our fillings, then fish is adding a further 2.3 mcg and the environment contributes just 0.3 mcg.3
And the process of leaching—where fillings are constantly releasing mercury—begins almost immediately, within a day of the filling being placed, a new study has found, so confounding the belief that it happens only with worn and old fillings. When researchers at the University of Peshawar in Pakistan measured mercury levels in blood, nail, urine and hair samples before and immediately after the use of an amalgam dental filling, they discovered that levels were up to eight times greater a day after the procedure compared with the controls who didn’t get a filling.4
The smoking gun
So what damage is mercury doing to our health? There are too many lifestyle variables to absolutely establish a direct cause-and-effect between mercury levels and disease, but common sense would suggest that having one of the world’s most toxic metals in our body must be doing some damage. It’s smoking-gun evidence: we can’t see it directly, but we have the next best thing—all the evidence is pointing in the same direction.
It’s established that mercury poisoning, or hydrargyria, can damage the brain, kidneys and lungs, and symptoms include impaired vision, hearing, speech and muscle coordination. Mercury is also suspected to play a part in autoimmune and neurological diseases like Alzheimer’s and multiple sclerosis (MS).
Indeed, Prof Boyd Haley at the University of Kentucky has proposed the hypothesis that elemental and organic mercury compounds, among other brain toxicants, are one major cause of Alzheimer’s.5
In one lab test, researchers at the University of Calgary in Canada discovered that when neurons were exposed to mercury ions, the metal disrupted their membrane structure and growth rates, and disintegrated cellular proteins. The affected nerve cells also formed abnormal patterns of ‘sprouting’ known as ‘neurofibrillary aggregates’, which are typically observed in the brains of Alzheimer’s patients.6
There’s also anecdotal evidence from people who’ve had their amalgam fillings removed and then experienced sudden improvements in chronic health problems. Six separate surveys involving 1,569 patients, all of whom had gone through amalgam removal, reported improvement—or, in some cases, complete reversal—of a range of problems, such as chest pain, depression, fatigue, gastrointestinal issues, migraine headaches, MS, memory loss and irregular heart beats, or arrhythmias.7
There is also further smoking-gun evidence from dental clinics themselves. Dental assistants reported significantly higher levels of neurological and psychosomatic problems, memory loss, inability to concentrate, fatigue and sleep disturbances than did healthcare personnel not regularly exposed to mercury fumes.8
While definitive proof that mercury from fillings causes serious health problems may never become available, there’s enough evidence to raise the question: why should you even take the risk, especially when safer alternatives are available?
A dental paradox
There’s one chronic condition that amalgam fillings can cause: periodontal, or gum, disease.
At least nine separate studies have demonstrated that they are causing gum problems, says the University of Calgary’s Clinical Associate Professor Murray Vimy.
“Periodontal disease is one of the most prevalent chronic diseases in man, and mercury fillings contribute significantly. The ADA [American Dental Association] and its advisors may be knowingly misinforming the public through the media, or they lack the understanding of the scientific research about mercury release from amalgam published in their own journals,“ he says.1
The yes boys take over
Amalgam was controversial almost from the day it was first formulated (it’s a mix of silver, tin and copper in liquid, or elemental, mercury). It was seen as a more pliable, durable and less costly alternative to gold, which was then routinely used to fill cavities.
But from the outset, leading American dentist Chapin Harris refused to handle the new material, describing it as “one of the most objectionable articles for filling teeth that can be employed”.
America’s first dental association, the American Society of Dental Surgeons, which Harris had co-founded in 1840, disbanded over the controversy in 1856 and was eventually replaced by the American Dental Association in 1859. The ADA was more welcoming of the new material—and remains so to this day.
Women and children first
Only people with a ‘mercury allergy’ or sensitivity to mercury are at risk from its effects, and that’s just 3 per cent of the population, say the dental associations. Even then, that’s still a substantial number of people, equating to around 1.8 million people in the UK and 9 million in the US.
The only others who should avoid amalgam fillings are pregnant women and new mums who are breastfeeding. As for the rest of us, our kidneys will take care of any mercury and it passes through us every day—or so the dental associations tell us.
But the World Health Organization isn’t so sure; in one study, WHO researchers discovered that people with the most amalgam fillings—which were leaching up to 100 mcg of mercury every day—were excreting just half that amount in their urine.1
This inefficient clearing may be down to age. One study of 507 schoolchildren (ages eight to 10) found that those with amalgam fillings had significantly higher levels of mercury in their urine during the first two years of follow-up. But over the full seven years of follow-up, their levels were not significantly different from those in children who had received resin composite fillings instead. This suggests that these children’s bodies had the ability to shed the toxic mercury load.2

Scientific Panel Calls FDA Miserable Failure in Protecting Children from Mercury

December 28, 2010 | 31,801 views


amalgam fillingsA U.S. Food and Drug Administration (FDA) advisory committee has recommended that the agency take a new look at updated data on mercury amalgam dental fillings that may indicate medical problems for patients.
The committee also said that more information on amalgam fillings should be posted for both for patients and dentists.
According to CNN:
"Public pressure prompted the panel's review, initiated less than 18 months after the agency's decision. Committee members listened to testimony by consumer and dental groups claiming the FDA used flawed science when it set the current guidelines for mercury safety levels."


Dr. Mercola's Comments:

Thanks to a massive response from grassroots America to the U.S. Food and Drug Administration's (FDA) abysmal 2009 amalgam rule, the FDA agreed to re-examine its pro-mercury fillings position at a hearing earlier this month.
Well, the hearing was a major success!
A government panel of scientists, after two days of hearings before its Dental Products Panel, has determined that the FDA is failing to protect children, pregnant women, hypersensitive persons -- and the rest of us -- from the dangers of mercury fillings.
Charlie Brown, the national counsel for Consumers for Dental Choice and the president of the new World Alliance for Mercury Free Dentistry, says:
"[This] decision is a resounding defeat of FDA and its policy of protecting dentists' profits instead of protecting children's health."

We're Making Progress, but the Fight is Not Over

For the last year we have been working alongside Charlie Brown to help eliminate the use of mercury in U.S. dentistry -- and we've made some major strides.
Most recently, Costa Mesa, California has set the precedent by becoming the first city in the United States to pass a resolution to immediately ban the use of mercury amalgams in dentistry.
This success story was made possible by a trio of Orange County, California activists who distributed flyers explaining the hazards of amalgam (unfortunately, most people are still not even aware that "silver fillings" contain mercury!). They allied with health professionals and green businesses for support.
They organized an extensive petition drive, collecting signatures from individuals asking city council to ban amalgam -- both by asking people directly to sign, and by enlisting friendly health professionals and businesspeople to keep the petitions in their front offices.
They surveyed all the city's dentists, and presented certificates to dentists who are mercury-free.
Then, they sought out Councilman Gary Monahan, who agreed to sponsor a resolution calling on the federal and state governments to "eliminate the use of mercury in dental practices ...immediately," and, at the local level, requesting that every dentist cease using this poisonous material.
Thanks to the testimony of an array of dentists, a dental hygienist, chiropractors, victims of mercury toxicity, businesspeople, a scientist, a Navy veteran, and a lawyer at the City Council meeting reviewing the Monahan resolution, it passed unanimously -- and Costa Mesa became the first locality in the United States to call for a ban on mercury fillings.
The FDA hearing earlier this month also made some favorable strides for this movement.
The scientists told the FDA to tell U.S. dental patients, starting right now, that amalgam is mainly mercury, and to tell U.S. dentists to stop giving amalgam to children. They also recommended that the FDA come up with models that show the effects of mercury vapor exposure from dental fillings, as well as review more data on the impact of these fillings on children and fetuses.
The bad news, however, is that the entire matter will now be returned to FDA's board for consideration, which, Brown notes, is "notoriously pro-mercury and pro-American Dental Association."
The FDA does NOT have to follow its committee's recommendations, and, unfortunately, the FDA has a history of ignoring its panelists' advice if it doesn't uphold the pro-industry position -- even to the point of disagreeing with their own FDA scientific experts.
This is precisely what happened in 2009 with their disappointing "final rule."

The FDA is STILL Protecting Industry Over the U.S. Public

The FDA has long been the world's number one protector of mercury fillings, and the U.S. is lagging behind the rest of the world, and even behind some third world countries, in protecting its citizens from this toxic product:
  • Canada advised dentists to stop placing amalgam in children and pregnant women in 1996!
  • Denmark, Norway and Sweden have essentially banned amalgams.
  • There are 5,636 hospitals in developing countries that are committed to or already mercury-free. The majority of these are in the Philippines, India and Argentina.
Yet, in the United States four out of five dental specialists still use amalgams, and the material is still endorsed by the American Dental Association.
FDA Commissioner Margaret Hamburg even has an egregious conflict of interest on amalgam, yet participated in the rule making. Hamburg entered the FDA through the revolving door after making millions as the director of Henry Schein Inc., the largest seller of amalgam.
The FDA is so much in the pocket of corporate America that it not only allows mercury-based dental filling to be implanted in children and pregnant women, but it covers up the very fact that these fillings contain mercury, which is a known toxic substance.
And the FDA's rule ignores the fact that Americans are getting mercury from so many other sources (vaccines, fish and seafood, household products, paints, pesticides, etc.) that many teenagers and adults are saturated with these neurotoxins.

Another Call to Action: We're So Close, Help Keep the Momentum Going!

Even the FDA is finally starting to realize it has become a pariah in the world by covering up the massive harm being done by the continued use of mercury fillings.
Now that the tide is turning, pro-mercury dentists, the FDA, and the world need to know that consumers like you will not tolerate dental mercury -- a neurotoxin and a pollutant -- any longer. Just like Costa Mesans have made it clear that the use of amalgam is no longer acceptable in their community, it's time to get this substance OUT of U.S. dentistry.
I urge all of you reading this to tell Jeff Shuren, director, FDA Center for Devices (Jeff.shuren@fda.hhs.gov or 301-796-5900), that we have waited long enough -- and that it's time, this month, for FDA to:
  1. Tell Americans amalgam is mainly mercury
  2. Protect Americans from mercury amalgam, starting with a ban on amalgam for children and pregnant women.
Tell Dr. Shuren, too, that Canada gave these warnings 15 years ago -- which means that an entire generation of U.S. children has grown up unprotected from amalgam's mercury, and that we will not stand for any more harm to be done to future generations to come.
You can also ask Dr. Shuren:
  • Why does the FDA approve of dentists telling parents amalgams are "silver fillings"?
  • Why does the FDA ban mercury for treating the legs of race horses but say it's fine implanted in a human child?
  • Does the FDA say increased amalgam use is a "positive health outcome" in order to pump up the sales for Henry Schein Inc., Commissioner Margaret Hamburg's company?
Together we are making a real difference and with continued passion and support on your part we can WIN! Let's protect the health of Americans, including that of future generations, from toxic amalgam by getting "silver fillings" banned from U.S. dentistry once and for all.
