Mercury fillings, also
called “silver fillings” in an attempt to subvert your attention away
from the “mercury” component of the filling, became
popular in usage back in the days of the Civil War because mercury was
cheap and inexpensive to obtain, and mercury was not yet known to be
poisonous. The use of mercury to fill cavities represented the most
modern technology at the time, and they did save many people from having
to loose their teeth. It served its purpose during a time when the only
option was extraction if your tooth contained serious decay.
Have there been any advances in the
dental field in the last 150 years since the Civil War? Of course. Not
only have today’s dental materials, procedures and tools advanced to a
far superior degree, but also we have advanced in awareness and
knowledge of the human body and the effect of these materials on our
health.
Mercury is now known to be one of the most poisonous substances on the planet. Mercury fillings are typically called “amalgam” fillings or even “silver” fillings, although they contain little silver. The fillings are composed of 50% mercury.
So why are they not called “mercury” fillings? The main reason why is
because no one would want the filling if they were aware that they were
pouring hot molten mercury into their mouth to sit there for many years.
We were all taught as children not to play with thermometers or break thermometers because of the danger from the mercury. Even just the vapor from the release of the mercury can be dangerous.
We would no sooner want arsenic or lead poured into our mouth than we
would want mercury. Therefore, by calling it a “silver” filling, the
public often is unaware of the nature of the substance that is being
used in their filling, although public awareness is growing.
For this fact alone, the best Dentists
avoid the use of mercury fillings, aka silver fillings or amalgam
fillings, and seek instead the use of more superior and healthy modern
materials. Here are some important facts that you should know regarding the use of mercury fillings:
- Amalgam or silver dental fillings are composed of fifty percent mercury.
- Mercury has been deemed as one of the most toxic substances on
earth. In fact, there is a field of science that has developed called
“mercury toxicology”. These toxicologists have learned that no amount of
mercury vapor exposure is harmless.
- OSHA stands for the
Occupational Safety and Health Administration. They are a federal agency
that enforces the legislation of safety and health. This organization
has classified dental amalgam as a toxic and hazardous waste.
- EPA
(Environmental Protection Agency) also has deemed dental amalgam as a
hazardous material. Both the OSHA and the EPA require that all amalgam
removed from your teeth has to be stored in a special container to
prevent human and environmental exposure to mercury vapor.
- Scientific research is available that demonstrates the damage of
mercury, even in relatively small amounts, on the brain, lungs, kidneys,
nervous system, glands, heart, hormones, enzymes and blood cells. It also has been proven to suppress the immune system up to 100%!
Mercury has been proven to pass readily
through the placenta in pregnant women and cause permanent damage to the
delicate developing brain of the baby. After placing an amalgam filling
in a pregnant woman, mercury has been shown to appear in the amniotic
fluid just 2 days later, and the breast milk is also laced with
concentrated amounts of mercury after the mother receives a “silver”
filling.
Mercury vapor is released continuously
from amalgam fillings, and is increased up to fifteen fold during
chewing, brushing, drinking hot fluids, and eating foods that are
acidic. The vapor released by mercury fillings is absorbed rapidly by
the body and accumulates in your tissue.
Studies
by the National Institute of Health have confirmed a direct link
between the levels of mercury in a person’s blood, stool and urine, and
the number of mercury fillings they have in their teeth.
In studies of human autopsies, a direct
correlation has been discovered between the amount of mercury found in
the brain, and the number of amalgam fillings in the teeth. The brains
of individuals who died with Alzheimer’s disease were found to have high levels of mercury in the brain.
Amalgam fillings (mercury fillings) do not bond directly to the teeth. This creates 2 problems.
- First, it means that a larger amount of healthy tooth structure must
be drilled away in order to lodge the filling in place. This weakens
the tooth unnecessarily.
- Secondly, it means that, because a tight bond is not created between
the filling and the tooth, bacteria can more easily enter between the
filling and the wall of the tooth, causing unseen decay to grow
underneath the filling or alongside it.
Armed with today’s knowledge
and advancements, there is no reason why modern day dentists should be
stuck using 150 year old materials that are now proven dangerous.
The best dentist today would offer and use the outstanding alternatives
to mercury fillings that exist. They are far superior and actually look
like real teeth. For smaller cavities, composite resin fillings that
are tooth colored work excellently. For larger cavities, reinforced
porcelain or even resin inlays or on lays are available. These are
custom made in a dental laboratory. They
are not only beautiful, providing a true restoration of your natural
tooth, but they also are bonded directly to the structure of the tooth
so that the final result is strong and more resistant to bacteria
invading cracks.
