Hi Nelson,
      
    Fist, I would suggest to stop chewing on Aluminum because it is NOT 
good for your teeth and will cause physical damage to its structure and 
integrity or TOOTH ABRASION (or occlusal abrasion). This can expose the 
sensitive DENTIN layer of your teeth which can cause PAIN via NERVE fibers 
in your tooth pulp/canal.

    Second, I am not an expert in chemical reactions but I do know that 
AMALGAM (tooth fillings) is composed of 40-45% Mercury and elements of 
silver, tin , and copper BOUND into a metallic complex from which Mercury 
is NOT FREE.  Small amounts of mercury do VAPORIZE from the surface of 
fillings overtime, pass into the air and is EXHALED. Most of the mercury 
that is absorbed into the body is excreted by the kidneys in the urine.

    Mercury has been shown to accumulate in body organs such as the brain, 
lungs and liver BUT NOT cause TOOTH PAIN per say. However, REPEATED 
scientific studies in Humans with and without amalgam fillings show no 
significant diffrence in these ORGAN systems function and health.  That is 
why the Food and Drug Administration (FDA), the National Institute of 
Health (NIH), the National Institute of Dental Research (NIDR) and a host 
of other health agencies attest that dental amalgams are SAFE to use.

    On the side though, we also get exposed to mercury from other sources 
like eating SEAFOOD.  
   The daily intake of mercury attributable to dental amalgam fillings, as 
measured by blood levels of mercury, is ONLY 14% (1/7th) of the amount 
measured from EATING a seafood meal a week.

  Hope this helps you and clears the MERCURY MYTHS about Dental amalgams 
safety.
