Amalgam is commonly referred to liquid or solid alloy of mercury with metals. The amalgams used in dentistry are composed of mercury and a metal mixture (silver, tin, copper and possibly trace amounts of zinc) in a ratio of 1:1 together. Apart from the cheaper amalgam filling material is superior to the inlays of gold alloys or ceramics because of better marginal fit and its good mechanical properties. Unlike before, we now know that amalgam fillings release mercury to the hardening and contribute to human exposure. Mercury is next e.g. in thermometers, skin disinfectants and paper, but also in the food chain (pollution). It is partially absorbed into the body, deposited, and only very slowly excreted.
The release of mercury from amalgam is increased.
* Mechanically by chewing, teeth grinding or brushing teeth.
* Chemically by acidic or hot foods, but also by poor oral hygiene (pH, plaque colonization).
* Metal electrochemically more noble by contact.
The release is also dependent on the nature and processing of the material (e.g. fillings give off less polished). Particularly large amounts are released during laying and polishing of new fillings and drilling out old fillings.
How does the mercury get into the body?
* Via the lungs (inhalation of the fumes).
* Via the gastrointestinal tract (swallowed).
* On the root (especially in the absence of lining), gums and jaw bones.
* Through the nasal cavity.
From the mouth or nose area, the mercury by diffusion directly into the brain. Another way is through the bloodstream, where the mercury is either deposited in various organs or the nerve pathways to the brain transported.
What health effects may occur?
There are no typical symptoms of mercury poisoning. A variety of very different clinical pictures are taken in the literature in connection with amalgam, such as
* Susceptibility to infection.
* Diarrhea, nausea.
* Depression, anxiety.
* Irritability, sleep disturbances.
* Headache and muscle pain.
* Skin reactions.
* Hearing and vision problems.
* Anemia (anemia).
* And many other symptoms.
The influence of mercury on the most appeal, however, images can ultimately be proved neither unequivocal nor refuted. A real "mercury allergy is rare (less than 0.2%).
What you can do:
* Has found the doctor based on the saliva test or other methods that you might be at a heavy metal pollution may be possible that amalgam fillings your teeth may be to blame.
* Before you decide on a comprehensive dental treatment, you should try to rule out other possible causes, for the replacement of amalgam fillings is very time consuming and is funded by health insurance very often.
* The mercury that remains available even after the removal of the amalgam still in the body is excreted slowly. For stubborn cases, there are drugs ("chelating agent"), which accelerate the excretion. TS / jk / Miscellaneous / amalgam problems - 22.02.2000-jk
When to go to the doctor:
Through increased mercury exposure, you should consider when you are more or less frequently, more or less show disease symptoms, without adequate or that could profound diagnosis. Find a doctor you trust and talk to him about your concerns you may have due to amalgam fillings.
What your doctor can do:
* If you suspect mercury levels, various tests are carried out. However, they are often inaccurate (saliva test) and expensive. The cost of these tests with the patient.
* If you suspect mercury allergy can be performed by the dermatologist an allergy test.
