some facts you many want to know
what is a mercury/silver filling?
It is a silver/grey filling that is usually placed in the molar and premolar teeth. It consists of a mixture of different metals namely,
Mercury – 50%
Silver – 28%
Tin – 14%
Copper – 8%
As you may notice, 50% of the filling consists of mercury.
I’ve had mercury filling for years, why should I remove them?
Most of the mercury fillings that a person has in their teeth were placed many years ago. Those fillings are indeed very strong and will probably last for many years. The problem with these fillings is not the effect they have on the tooth but rather the effect they can have on the body.
what problems can mercury cause?
Mercury is the most toxic, non-radioactive element on the earth. Most medical and scientific researchers have called for a ban on the use of mercury in all products. However, the potential harmful effects of mercury fillings have been ignored by most government institutions. Due to its poisonous nature, mercury can adversely affect the immune, urinary, cardiac, respiratory and digestive systems. Under laboratory conditions, mercury has produced brain cell deterioration identical to that seen in victims of Alzheimer’s disease.
should I get my mercury filling removed?
Mercury vapour is continuously emitted from mercury fillings, which means that you are directly exposed to mercury every day. The output of mercury vapour can be intensified by the number of fillings present and other activities associated with the human mouth, such as chewing, teeth grinding and the consumption of hot liquids. Studies repeatedly demonstrate that even low levels of mercury cause measurable adverse health effects. The damaging effects of this exposure may not manifest for years or even decades but why wait for problems to occur.
The World Health Organization has concluded that dental fillings contribute more mercury to a person’s body than all other sources of mercury combined. No amount of exposure to mercury vapour can be considered harmless, especially considering its cumulative effect.
if mercury fillings are so bad for you why aren't they banned?
The governments of Norway, Sweden, and Denmark already banned the use of mercury fillings in dentistry back in 2009. Germany and Canada have limited their use for pregnant women and France, Finland and Austria have recommended that alternative dental materials be used for pregnant women.
In South Africa we are still allowed to use mercury fillings. Do these other countries know something we don’t? Why do some countries ban these fillings only in pregnant woman and children? Makes you think.
what are the disadvantages of removing mercury filling?
When removing a mercury filling you also remove a small portion of the surrounding tooth structure. This is done to insure that the new white filling binds to healthy enamel or dentine. White fillings tend to leave the tooth a little sensitive for a few days but that should settle within a few days. Another problem is that in certain cases the mercury filling is so big that you can’t place a normal white filling. In these cases you need to have a crown made.
won't I be exposed to mercury during the removal?
Unsafe removal of amalgam fillings can cause more mercury-related health problems to patients because mercury vapour is released in greater quantities as a result of drilling. For this reason, these fillings have to be removed utilizing specific protocols and specialised techniques.
is there a proper way to remove mercury fillings?
To prevent additional mercury exposure a dentist should follow the amalgam removal protocols:
Utilizing an efficient suction system in the oral cavity with a special tip or its equivalent to contain amalgam particles and mercury vapours.
Operating a vacuum system at maximum efficiency.
Applying a rubber dam to isolate the teeth with the mercury fillings being removed.
Applying copious amounts of water to the filling during removal.
Removing the amalgam in large segments to minimize the generation of mercury vapour and amalgam particulate.
Using an additional suction unit to remove any mercury vapour.
