FDA
does " about face " on dental
amalgam
|
After
decades of claiming that there is no valid
scientific evidence to show that dental amalgam
can cause health problems ( mercury based filling
also called silver fillings ) the American Food
& Drug Administration ( FDA ) has slowly
begun to change it's position following a lawsuit
by consumer advocates in the USA. For a look at a
list of somes studies linking the adverse effects
of mercury on various human biological system CLICK
HERE. Judge for yourself if you think
they are valid or not....
The FDA first posted the following
on it's website: " 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. "
Subsequently,
after lenghty backroom maneuvering, the FDA
removed that webpage and replaced it with another
one where they state: " Dental amalgam
contains elemental mercury. It releases low
levels of mercury vapor that can be inhaled. High
levels of mercury vapor exposure are associated
with adverse effects in the brain and the
kidneys. "
Of
course the fact that dental amalgams release
mercury has been known and proven a long time
ago. The fact that mercury is a potent
neurotoxin is also a proven fact. Mercury is a
fat soluble heavy metal that can accumulate in
body tissues especially when a person's ability
to efficiently detoxify is impaired. The FDA does
not mention the risks associated with chronic
accumulation and retention when there is ongoing
low level exposure to Hg vapour as is the case
with amalgam fillings. There is also no mention
of the conversion of elemental mercury into its
organic form through methylation by bacteria in
the body.
So
why has it taken so long for the FDA to at least
admit that mercury is released from amalgam and
that it can cause health problems, at least in
some population groups ? Regrettably that change
has not come about willingly from the FDA. In
fact the FDA had been dragging its feet for so
long on mercury in dental fillings that even a
judge, Ellen Segal Huvelle of U.S. District Court
for the District of Columbia, castigated the
agency: This is your classic failure to
act, she said.
It
seems that the policy is to deny the problem
unless they have no choice and then admit only
what they have to. A few decades ago the position
what that mercury was bound in amalgam so was
safe. It took that long to finally admit that
mercury is IN FACT not bound and is actually
released from amalgam. For more information see

More importantly if you suspect
that you have a problem related to your amalgam
fillings, it is crucial that you do not rush to
have them removed. Seek advice from well informed
health practitioners as issues with dental
material biocompatibility,
individual variations in detoxification,
potentiation from other toxicants and suitability
of treatment
protocols can have a significant
impact on the outcome of treatment.
Our staff at Integrative Centre
for Dental and Natural Health have decades of experience and
expertise with amalgam related
problems and, more importantly, with other health
problems that can frequently be combined with
mercury toxicity issues.
