Why to replace Mercury (Amalgam) Fillings read
Mercury from fillings contributes 3 to 4 times more
mercury to our bodies than all the environmental sources combined.
Many people still don't realize that the majority of the new
cavities we see in children today occur just in the center of the molar teeth. The tiny
groves there are flaws which invite early decay. By the age of 6 a child has 4 permanent
Mercury fillings require the removal of the middle third
of the tooth. The material itself is weak and cannot be used in a thin layer. The
dentist must drill deeply into the softer dentin area of the tooth and drill undercuts
into the healthy tooth even where there is no disease. This approach was developed in
1908 by G.V. Black. As a result of this kind of filling, the tooth is now weakened by
Mercury fillings also expand after being placed in the
tooth. The bigger the filling the more they expand. If any moisture gets into the filling
they expand rapidly. Temperature can also cause expansion. All this expansion within
the tooth eventually results in fracture.
Once broken the tooth may require a root canal or crown or
extraction. Often the fracture is so severe that in spite of all efforts the tooth is
Metall free fillings:
Composite fillings materials (with porcelain
Lab processed composites fillings
Lab processed porcelain fillings
Last two have solved the wear and placement
problems of the composite fillings.
The cheapest Choice:
Composite Filling Materials
If you are restoring a tooth for the first time then
composite filling materials will not only strengthen the tooth as well as provide
greater longevity and beauty than the mercury/silver ones but, more
importantly it is far less damaging to the healthy tooth.
The majority of initial composite fillings require only
minimal natural tooth removal and not only restore decayed areas but also seal up weak
spots so decay will not penetrate the other surface groves.
Sealed surfaces ARE protected as long as the sealant
lasts. When it wears out it can easily be reapplied until the child grows out of this
cavity prone period. However, the composite sealant must be placed before decay begins. On
the average 36% of the children today are cavity free. However, those children raised in
the southwest are much more likely to be cavity free than those from the northeast. No
single cause can be found for these differences.
Earlier Composites were not
strong enough for replacing big mercury/silver fillings in the hard-biting back teeth. As
a result, stronger and better light cured materials have been developed,yet technical
problems still exists in placing these restorations. They shrink 1% to 3% upon setting and
lack the crushing strength to withstand the enormous biting forces some people can
generate. Sensitivity and recurrent decay results from the shrinkage and excessive wear is
the result of low strength.
Progress for the 1990's: Indirect Composites
Since the mid-80's a new system, called indirect
composites combines the best of the composite and the strength of a natural tooth.
This inlay process is much easier on the patient (and dentist) and has virtually
eliminated the two major drawbacks to the composite restoration.
If you want to replace amalgam, please read first this :
The IAOMT recommended
patient protection procedure for mercury/silver replacement is to:
First: Protect the patient's breathing zone. Drilling
out old fillings can release enormous amounts of mercury into the air. If the patient is
given a nasal hood this exposure can be prevented. Many dentists recommend a rubber dam..
Second: The dentist should cut the fillings in half
or quarters with a small burr and lots of water then remove the pieces. This avoids
excessive drilling of tooth or grinding on the old fillings.
Third: The tooth is cleaned and shaped with a diamond
burr, some undercuts may be removed, and an accurate impression is made. Here technique
may differ from office to office. Dentist will
temporize the tooth with a light cured temporary composite and send the patient home.
Fourth : Dentist then make a model of the tooth
preparation in out lab and fill the preparation with a good quality posterior composite.
This filing is first set with light and then heated or baked at 270o F for 14 minutes.
Once baked the filling is then etched with acid and sand blasted so it can be
bonded to the tooth.
Last: The patient returns usually in a day or
two and the temporary is removed. The tooth is cleaned and prepared for bonding. The Bowen
system is currently the strongest in attaching the new filling to enamel and dentin. With
the newest generation of dentin bonding the filling can be essentially welded to the
remaining tooth structure. Once completed the bite is adjusted and margins polished. This
restoration can be virtually invisible to the naked eye and feels wonderful.
Some situations will still require a full (or partial) crown
but almost any tooth that can hold a filling now can be restored with this procedure.
The baking process more completely cures the filling and
greatly increases the crushing strength.
Minimal uncured chemical resin is left and the result is a
much stronger wear resistant and far less toxic filling. In addition the shrinkage takes
place outside of the mouth and the small gap that results will be filled with a thin layer
of composite resin cement. The welding of the filling to the tooth makes the tooth
stronger and more resistant to fracture.
Children born today need never have the mercury packed
into their teeth that we did.
Those of us who already have the large mercury/silver
fillings must consider how best to restore our teeth.
The larger the cavity the worse a composite filling will
hold up. Excessive wear especially becomes a problem for some brands when used in molar
teeth. If the decay has penetrated deeply in between the teeth composites can leak and are
more difficult to place. Lab processed composites and porcelain fillings appear to have
solved both the wear and placement problems.
As to expense, the initial cost of a filling must be weighed
against the long term expense. Fillings which require the dentist to remove excessive
amounts of good tooth structure are not cheap. Which is best?
My first recommendation is to prevent the cavity if at all
possible. Seal out decay. If the damage is already done then repair it with the most
durable material available and try harder to prevent the next cavity. As Hippocrates said,
"First and foremost do no harm". I don't think he would have approved either
toxic fillings or drilling away the good tooth.

Dentists have the highest suicide and divorce rates among professional. Female
dental personnel have a higher spontaneous abortion rate, a raised incidence of premature
labour, and an elevated perinatal mortality.
Research has demonstrated that 100% of all root canals result in residual
infection due to the imperfect seal that allows bacteria to penetrate. The toxins given
off by these bacteria are more toxic than mercury. These toxins can cause systemic
diseases of the heart, kidney, uterus, and nervous and endocrine systems.
