Introduction
Mercury is a neurotoxin and the most poisonous, non-radioactive, naturally
occurring substance to which we can be exposed. Chronic mercury poisoning
has reached pandemic proportions in the United States and throughout the
world. It will directly or indirectly cause, contribute or exacerbate every
health issue known. The main cause: mercury amalgam (silver) fillings! It
has been conclusively proven that mercury vapor is released from amalgams
and stored in the body, and nearly 200 million people in the USA alone have
these fillings. While the placement and safe removal of these toxic fillings
is a dental issue, the effect caused by mercury vapor is a medical one.
My Position
I believe that chronic mercury poisoning is unquestionably under-diagnosed,
and the enormity of this problem makes it imperative that every health professional
understands how to diagnose and treat it. There is no doubt that unless the
medical profession addresses the issue of chronic mercury poisoning and provides
its patients with a sound and safe mercury detoxification program, any attempts
to treat their patients' current health problems will not achieve the
results desired by the practitioner and expected by the patients.
I've spent nearly ten years extensively researching chronic mercury
poisoning, from its source and how it affects health to the safest, most
effective, and
most natural way to remove mercury from the body. The result is my newest book,
Mercury Detoxification: The Natural Way to Remove
Mercury from Your Body. The
book clearly explains how mercury affects the body, while guiding the reader
through every step of the mercury detoxification process, including the following:
• testing for mercury;
• pharmaceutical chelators;
• intestinal and brain support;
• and the relationship of amalgam fillings to autism.
The book contains over 240 references and an extensive index and
glossary. You can use it both for your own background knowledge and
as an educational tool for your patients, taking advantage of my efforts
without reinventing the wheel. Both the book and referenced abstracts
are available on my website.
Because I believe it is so important to understand the need and value
of a mercury detoxification program, I've chosen to provide you
with some insights into the following:
• the reason we've become so mercury
toxic;
• the primary source of mercury exposure;
• the ways in which mercury affects the body;
• and the need to educate yourself about mercury detoxification.
I hope this article will stimulate your concern, interest, and curiosity
enough to learn more about what I consider one of the most significant
and pervasive health problems of the twenty-first century: chronic
mercury poisoning.
Brief History of Amalgam
Because amalgam fillings are the most common source of mercury exposure, I
felt it would be worth knowing why they are still being used today and why
you cannot count on the American Dental Association (ADA) to educate the
layperson, or the health professional, about the health hazards of these
fillings. Amalgam was introduced in the early 1830s. It consisted of 50%
silver filings and 50% elemental mercury. At that time, physicians also practiced
dentistry, and because they knew mercury was a poison, the medical association
banned its members from using it. But in those days, too, anyone could pull
and fill teeth, and a number of the trades, referred to as "barber" dentists,
began using amalgam. Because it was so inexpensive and easy to use, amalgam
became very profitable for these "dentists." Seeing a significant
revenue flow being lost to barber dentists, a group of doctor-dentists led
a coup against the medical profession's ban on mercury. This took place
in 1859 when they officially split from the medical profession and started
their own association, the American Dental Association.
What is the significance of the 1859 revolt? First, it legalized amalgam
fillings. Second, it legitimized the right of dentists to poison their patients
with
mercury. From the beginning, the ADA denied mercury vapor was released from
amalgams, but since such release has been conclusively proven, the ADA has
finally acknowledged that fact. Yet instead of leading the effort to ban these
toxic fillings, the ADA has taken a new, but indefensible position, by saying
the amount of mercury released is so small that it doesn't constitute
a health hazard. Once again, the ADA asks the public to trust it with their
health.
What the ADA won't tell you is that mercury is far more poisonous than
arsenic and lead; even one atom of mercury in the body is toxic. Simple logic
dictates that because mercury vapor (80% of which enters the body) is indeed
released from amalgam fillings, such fillings should be deemed a health hazard
and be banned immediately. (The irony is that 150 years ago, the medical profession
considered it malpractice to place amalgams. Today, the ADA considers it malpractice
to recommend their removal.)
The fact is that every patient you see who has amalgam fillings is mercury
toxic to some degree. In the following sections, you'll learn how mercury
is released from amalgam fillings and why so many people are being poisoned
by it.
Amalgam Fillings and Chronic Mercury Poisoning
The amount of mercury vapor released from an amalgam filling is directly proportional
to the temperature. In fact, heating the filling by such common actions as
chewing, brushing your teeth, and drinking hot liquids can cause a significant
release of mercury vapor.
Other procedures can also dramatically increase
the release of mercury vapor:
• when amalgams are placed into a cavity;
• when amalgams are removed;
• when amalgams are polished;
• when a gold crown is next to an amalgam filling;
• when you grind your teeth; and
• when teeth are cleaned.
Depending on the number of fillings present and
the type and duration of filling stimulation, measurements of mercury vapor
in the mouth can range from
36 mcg/m3 of air, when the filling is at rest, to over 4000 mcg/m3 (see
Table 1). The Agency for Toxic Substances and Disease Registry (ATSDR) has set
the minimal risk level (MRL) for continuous exposure to mercury vapor at
2.0 mcg/m3
of air per hour over a 24-hour period.
Table 1: Amount of Mercury Vapor Released
from Amalgam Fillings
Chewing Food: 68 mcg/m3
Tooth Brushing: 272 mcg/m3
Placing an Amalgam: 2000 mcg/m3 or more
Removing an Amalgam: 4000 mcg/m3 or more
Polishing an Amalgam: 4000 mcg/m3
As you can imagine, it's possible for filling stimulation to take
place throughout the day and during the night if one is a tooth-grinder
(approximately
50% to 90% of the population). Mercury vapor will also continue to
be released after stimulation for up to 90 minutes. Thus, everyone
with
amalgam fillings
is being exposed to varying amounts of mercury daily, for as long as
those fillings remain in the teeth.
Numerous other factors play a role in the amount of mercury vapor to
which a person could be exposed and accumulate, and that amount will
vary from
person to person. For example, the amount of mercury vapor released and
absorbed by
the above types of stimulation will be also be affected by the following:
• the number of fillings;
• the length of time they've been in the mouth;
• the size of the fillings;
• the frequency and duration of stimulation;
• the degree of the stimulation;
• and the health of the immune system.
For the majority of those with amalgam
fillings, the total amount of mercury received from their fillings in a 24-hour
period could easily surpass
exposure limits set by every regulatory agency. The irony here is that regulatory
agencies require that amalgam components be kept in a hazardous waste
container in the
dental office and also require that amalgam particles removed from
teeth be kept in a hazardous waste container; then what would you consider
a
tooth
with
an amalgam filling in it? Another important question the ADA has been
asked, but has not answered, is, why must every business using mercury be
monitored by regulatory agencies…except dentists? Table
2 shows the World
Health Organization's (WHO) list of the main sources of mercury.
Table
2: The World Health Organization’s
List of the Main Sources of Mercury Source: Daily Intake of Mercury (mcg)
Amalgam Filling: 3.8 - 21
Fish: 3.0
Other Foods: 3.6
Water: 0.05
Air: 0.04
Yet
in spite of the ever-increasing scientific evidence, the ADA continues
to state that mercury amalgam fillings aren't a health
hazard and insists
that mercury isn't stored in the body. To them, it's a little
mercury in and a little mercury out – with none left behind.
Of course that is a ludicrous statement, and numerous tests for
mercury have
been used to prove
that mercury does accumulate in the body.
The WHO has stated that there is no safe level of mercury and
just one mcg of mercury contains approximately 43,00,000,000
atoms of
it. (One
gram of
mercury, the amount found in just one large amalgam contains
1,000,000 micrograms – and
that is a lot of mercury!) Dentists are also mercury-toxic, and
their exposure to it could be even greater than those with amalgam
fillings. Of note is that
the dental profession in the USA places 100 million amalgam fillings
a year and uses 34 tons of mercury in the process.
Depending on the amount of mercury that daily accumulates in the
body, it can take a relatively long period of time before a related
symptom
appears. There
are two primary reasons for this. The first is that the body is quite
capable of removing mercury and other heavy metals, but that ability
will dramatically
decrease over time if the exposure to mercury isn't eliminated. The
second reason is because mercury is so ubiquitous. It spreads throughout
the
body and settles in every cell and tissue. That means it can take
years for
enough
to accumulate in any particular area of the body to generate an observable
symptom. Of course, how quickly a symptom or symptoms will appear
depends on the health of the immune system and the interaction and
extent of
the factors
previously discussed.
It shouldn't be too difficult to see that even those with minimal
exposure to mercury from their fillings are still receiving a substantial
daily
dose of mercury. In spite of the evidence, the ADA's position is
that you aren't being poisoned until you express observable symptoms.
As
a health
professional, you know that argument is utterly without merit. Every
symptom related to chronic mercury poisoning has a threshold that
must be reached
before that symptom appears, but that doesn't mean you aren't being
poisoned prior to reaching that point. Other Important Factors to Consider
Space limits a detailed explanation of a number of other important issues relating
to chronic mercury poisoning but, briefly, consider the following:
• The Direct and Indirect Effect of
Mercury. Mercury poisoning is a double-edged sword. The direct
damage is caused when mercury attaches to proteins and enzymes
(anything with a sulfhydryl group is fair game), altering their function
and ultimately killing cells. Indirectly it can severely weaken
the immune system
and significantly deplete the body's most essential antioxidant, glutathione
(GSH), weakening the body's ability to deal with other toxins and free
radicals.
• Mercury Can't Be Detoxified by the Body. Everyone uses the term
detoxification, including myself, but the fact is that mercury can't be "broken" down,
and the body must physically remove it. In the process, two molecules of
glutathione are permanently lost for every atom of mercury that is removed
and millions of
atoms could be removed daily. This accounts for the depletion of glutathione.
• Mercury Doesn't Have a Half-Life. The fact is that mercury is not
a radioactive substance and doesn't decay. It must be physically removed
by a natural or pharmaceutical chelator.
The Long Reach of Mercury from Amalgam Fillings
Mercury released from amalgam fillings doesn't just affect those with
the fillings. The fact is that the first time a person can be exposed to mercury
from amalgam fillings is at the moment of conception. Mercury readily passes
through the placenta and enters the fetus, and if the mother has amalgam fillings,
the fetus is being exposed to the mercury released from them.
The fetus doesn't have an immune system to protect it, and even small
amounts of mercury will affect its development. The extent of the fetus's
exposure to mercury will depend on how much mercury is released from the mother's
fillings. Thus, it isn't difficult to imagine situations where the fetus
is being exposed to enough mercury to cause, or certainly contribute to or
make worse, every developmental and learning disorder, including autism. This
is indeed something to seriously consider when anyone tells you that mercury
amalgam (silver) fillings are not hazardous to health! There's no doubt
that mercury-containing vaccinations have played a significant role here, but
vaccinations don't occur until after birth.
Summary
Here is what we know:
1. Mercury is an extraordinarily poisonous substance
in very small amounts.
2. Even one atom will do some damage to the body.
3. Mercury is released from amalgam fillings, with the amount released
and stored dependent on a number of factors.
4. Everyone who has, or had, these fillings is being poisoned daily by mercury.
5. The body has the ability to remove mercury, but unless the source is removed,
it will become increasingly less effective at doing so.
6. Mercury accumulates in the body.
7. Mercury, because of its direct and indirect effects, can cause, contribute
to, or make worse any health problem.
In closing, I chose to focus on chronic
mercury poisoning instead of mercury detoxification because, unless
you understand the extent
and seriousness of this problem, I doubt you'd have much interest
in a mercury detoxification program. However, once you do make the
connection, all the information you need to know about detoxification
can be found in my book.
I believe you owe it to yourself, and your patients, to at least consider
the possibility that he or she could be suffering from chronic mercury
poisoning.
But you don't have to take my word for it. The fecal metals test is a
very simple, at-home, inexpensive, and non-invasive test to diagnose chronic
mercury poisoning in patients with amalgam fillings. (This test, available
at Doctor's Data, and other tests for mercury are explained in my book.)
You now have an objective method of determining if your patient is mercury-toxic.
If he or she is, the most obvious approach is to determine and eliminate the
source of the mercury and implement a mercury detoxification program to support
the body's efforts at removing it. My website, www.dentalwellness4u.com,
offers additional information on this subject and other oral health issues
that can negatively affect overall health. My website also has the largest
database of mercury-free dentists, providing a referral source for your patients.
I believe that diagnosing and treating mercury detoxification will benefit
your practice and your patients. At the very least, I hope I've provided
you some food for thought.
