Composite resin
fillings contain no mercury. They are bonded to the tooth and
therefore help prevent fractures of teeth. Amalgam (silver)
fillings expand and contract differently than tooth structure,
and crack and break the teeth they're in.
Composite
fillings can be contoured to the exact bite, are readily
repairable, and look absolutely fantastic! On the downside,
they are much more time consuming to place, and so are more
expensive, and some insurance companies do not pay well for
them.
Did you know
that the silver fillings in your teeth contains more than 50%
of the toxic element, Mercury? The argument rages as to
whether that mercury is bound, and therefore inert, or
actively liberated as mercury vapor which can then be absorbed
into body tissues throughout the life of the filling. Amalgam
is a material that is over 150 years old, and there are many
modern alternatives that can be considered.
The known
effects of mercury toxicity include deterioration of the
immune system, the neurologic system, and the reproductive
system. While I do not profess to be an expert on the
scientific evidence which I have become familiar with, I made
a choice many years ago, after having read a scientific
article which indicated there was suppression in the immune
system of monkeys in the experimental group (which had
recently undergone amalgam filling placement), while the
control group remained normal. The American Dental
Association's response was to state that "this research was
done on monkeys not humans, and therefore has no relevance. "
At that point, I asked myself what the American Dental
Associations was trying to cover-up?
Many
dentists who have read this page have asked me why I suspected
a cover-up? It is incongruous to me that the American Dental
Association tells us that mercury-amalgam is safe in our
patient's mouths, that once the silver and mercury have
hardened, there is no significant mercury vapor liberated from
the filling. In the same breath, they ask us to store all
unused amalgam in a sealed glass jar, with the scrap metals
underwater. So that makes two places amalgam is safe, in your
mouth, and underwater... sealed jar!
Read the ADA's guidelines for
mercury, and ask yourself, aren't they talking out of both
sides of their mouth? Is it any wonder that Scandinavia and
Germany, and most recently Canada have curtailed or banned the
use of amalgam? They provide no scientific research to verify
this, other than the Public Health Service study done earlier
in this decade. They fail to state that this study on the
safety of mercury indicated that further research was
necessary before any conclusions could be reached.
New! Dentists
around the nation have been blocked and sanctioned by their
state boards, and the ADA from explaining the risks of mercury
fillings. Several years ago, in an advertisement, I wrote "we
do not use the toxic substance mercury in any of the fillings
we place. " The NJ State Board of Dentistry fined me $500 for
false and misleading advertising. When I provided them with a
copy of the NJ Environmental Protection Agency's treatise on
the subject of mercury toxicity, they backed down.
What is the
ADA trying to cover up? I can only guess that they have been
endorsing the safety of mercury amalgam for so long, that a
reversal of position would create widespread fear in the
public eye, and reversal of trust with the profession. The
inexorable fact remains that many foreign governments'
regulatory agencies have banned the use of amalgam all
together, or in pregnant women and children under the age of
18. |

With that
evidence present, I have chosen to be extremely careful, not
just in placing amalgam in patients mouths, but in the removal
of old amalgam fillings I am proud to announce that our new
office is now equipped with special filters that remove
mercury waste from our drain lines, before it can get into the
sewer system (and the environment). We are one of only two
offices in NJ that are taking this extra step to protect the
environment, and to put our money where our mouth is. It costs
us substantially extra each month to do this, and therefore
other practices will be slow to jump on this bandwagon, and,
surprisingly, there are no regulations requiring dentists in
the US to trap mercury from waste water. There are, however,
over 50,000 such installations in Europe (many of which were
mandated by governments). |
