The
removal and the replacement of amalgam, the mercury based substance
used for dental fillings, is highly controversial. Most dental professionals
assert that the procedure is justified only in the rare group of
patients who are allergic to mercury. Yet others contend that amalgam,
although it is cost-effective, is toxic even in miniscule amounts.
They believe that over the years mercury could leach out of fillings
and accumulate in the kidneys, brain and other organs, causing such
ailments as allergies, migraines and fatigue. These doctors suggest
that many individuals could benefit from having their amalgam fillings
replaced with fillings made of another material, such as plastic,
gold or ceramic. Despite concerns about the safety of amalgam, the
material remains the most popular substance used for fillings in
the Us. However, some countries have banned the substances use in
dental care.
What is amalgam?
Commonly referred to as "silver" because of its shiny,
metallic gray color, amalgam has been used for more than 100 years
to fill dental cavities. Amalgam is a mixture of 53 percent mercury,
20 percent silver, 16 percent tin and 12 percent copper. It is cheaper
than other filling materials and is still considered safe and effective
by many dentists. An amalgam filling can usually last from 8-15
years.
The treatment
Those who endorse replacing amalgam fillings, specify that it be
done very carefully to prevent further poisoning. No more than five
fillings are removed per appointment in visits at least 10-14 days
apart. Insurers do not pay for the treatment except where there
is an allergy to amalgam.
The removal
of amalgam
Practitioners of this controversial treatment stress various safety
measures for those undergoing the procedure. To prevent swallowing
amalgam dust or breathing in mercury vapors that may result from
drilling, they recommend that the dentist use a dental dam, a thin
rubber film that covers and protects the mucous membranes while
allowing free access to individual teeth. They also urge that the
dentist use a slow drill, flush the mouth often with plenty of fresh
water and carefully vacuum out the metal debris. It is also important
that the dentist completely remove all potentially toxic materials,
including inlays or crowns that contain amalgam.
The view
point of mainstream medicine
The American Dental Association and all the dental schools in the
US endorse amalgam. They insist that the mercury in the fillings
is safe and that removal is unnecessary except when a patient has
an allergic reaction to the material. Others point out that mercury
from pollutants in the environment poses a higher risk than that
in amalgam fillings.
Extra
tip : Some people contend that
drilling out amalgam fillings can leave small amounts of toxic heavy
metals behind. They suggest drinking milk before treatment. The
milk reputedly binds to the toxins and makes it easier for your
body to eliminate them.
Elimination
procedures
Various natural
remedies have been advocated to remove mercury from the body, including:
- Homeopathic
remedies that contain very dilute, and therefore safe, amounts
of amalgam. These preparations are intended to remove any toxic
mercury buildup.
- Administration
of EDTA, a chelating agent that helps prevent mercury absorption
during the procedure.
Nutritional
measures
A number of nutritional therapies have been developed to complement
natural approaches to mercury poisoning. Some healers recommend
an increased dietary intake of various vitamins and minerals, especially
vitamins C and E, selenium and zinc, on the grounds that these substances
may bind to heavy metals and accelerate their elimination. Other
nutritional approaches include various fasting regimens.
Dental fillings
Some advocates of amalgam replacement and restoration advice against
immediately replacing amalgam fillings with new fillings made of
a different metal or combination of metals. They believe that saliva
and other oral secretions can possibly cause dangerous interactions
between traces of amalgam and the replacement metal. Instead, many
supporters of the procedure suggest the use of temporary fillings
composed of special plastic or cement materials. The fillings are
worn during an interim period of a few months after the amalgam
fillings are removed. Only after mercury is fully eliminated from
the body are the permanent replacement fillings put in.
Alternative
fillings
As an alternative to amalgam, gold, ceramic, glass-ceramic or plastic
fillings are available. However, do not accept fillings containing
barium or aluminium, or gold fillings made of so called poor man's
gold, which contains the possibly toxic metal palladium.
