Scientifically Proven Facts
  About Dental Mercury  
  
    
  
  1.
  Dental Amalgam contains about 50% Mercury.  
  2. Mercury has been scientifically demonstrated to be more toxic than Lead,
  Cadmium, or even Arsenic.  
  3. Mercury leaves
  dental amalgam continuously throughout the lifetime of the filing.(7)  
  4. Mercury vapour is the main way that mercury comes out of amalgam.(31)  
  5. Mercury vapour is absorbed at a rate of 80% through the lungs into the
  arterial blood. (31, 55)  
  6. Mercury is cytotoxic. Ie. It kills cells 
  7. There is NO harmless level of Mercury Vapour Exposure. (63) 
  8. Mercury from amalgam binds to -SH (sulphydryl) groups. These exist in
  almost every enzymatic process in the body. Mercury from amalgam will thus
  have the potential of disturbing all metabolic processes. ( 25, 33,60). 
  9. Mercury from amalgam is transported freely via the blood.(19,34,35,) 
  10. Mercury vapour is absorbed directly into the brain. (34, 55a)  
  11. Mercury from amalgam will result in a slow build up of mercury in body
  tissues. (20,26, 34)  
  12. Mercury crosses the blood brain barrier. (34,55a)  
  13. Mercury is implicated in the pathogenesis of Alzheimer's Disease. (67,68)
   
  14. Mercury from amalgam is stored in the foetus and infant before the
  mother. (20,61)  
  15. Mercury from amalgam is stored in the breast milk and the foetus up to 8
  times more than the mother's tissues. (18,19)  
  16. Mercury (Mercury Vapour / Methylmercury) crosses the placenta.(18, 31)  
  17. Mercury Crosses into breast milk.(18,31,61)  
  18. Mercury will severely reduce reproductive function.(2, 3, 4, 20, 22, 24,
  31, 37,38, 39, 40, 41, 49)  
  19. Mercury rapidly depletes the immune
  system.(27,34,35,42,43,44,45,46,47,48,60)  
  20. Mercury will induce a number of Auto Immune
  Diseases.(27,34,35,42,43,44,60)  
  21. Mercury will cause an increase in number and severity of allergies.(1,34,60)
   
  22. Mercury from amalgam is stored principally in the kidneys, liver and
  brain. (1,20,31)  
  23. Mercury from amalgam (shown in animal experiments) causes kidney
  damage.(59)  
  24. Mercury from will cause a 50% reduction in Kidney filtration as shown in a
  study of sheep after amalgam placement.(59)  
  25. Methyl Mercury is more toxic than elemental Mercury.  
  26. Mercury from amalgam is methylated in the mouth.(51,53,54,)  
  27. After chewing, Mercury Vapour levels will remain raised for at least
  another 90 minutes. (1,15,16,18,47)  
  28. Mercury from amalgam will migrate through the tooth.(25,27,30)  
  29. This rate of migration is increased if a gold crown is placed over a
  tooth filled with amalgam. (27,30)  
  30. Teeth are living tissue and are a part of our bodies.  
  31. Teeth have a massive communication via blood, lymph and nerves with the
  rest of the body.(34)  
  32. Mercury from amalgam is absorbed into the body at a rate of 3 to 17 mcg /
  day. ( WHO 1991 Criteria 118)  
  33. Mercury release is increased by; increases in temperature, friction &
  increase in electrical currents.(28,31,56)  
  34. Mercury from amalgam will enter the body as;  
  Elemental Mercury, Inorganic Mercury, Vapour, charged Mercury ions.  
  35. In the Brain, Mercury from amalgam is stored preferentially in the
  Pituitary Gland and Hypothalamus. (20,34)  
  36. Micro-Mercurialism is principally characterised by Neurological
  symptoms.(34)  
  37. Mercury is transported along the axons of nerve fibres.(33,34,50)  
  38. Mercury from amalgam may be stored in every other cell in the body. Each
  area affected will produce its own set of symptoms.  
  39. Mercury binds to haemoglobin in the red blood cell thus reducing oxygen
  carrying capacity.(1,16,17,21,26,35)  
  40. Mercury damages blood vessel reducing blood supply to the tissues
  (micro-angiopathies).(34)  
  41. Amalgam fillings produce electrical currents which might be injurious to
  health. These currents are measurable in Micro Amps. The Central Nervous
  System (Brain) operates in the range of Nano-Amps this is One Thousand times
  less than a Micro Amp.(28)  
  41A. Dissimilar metals in the mouth [eg Gold & Amalgam] will produce
  higher electrical currents.(19,30) 
  42. Mercury from amalgam (shown in animal experiments) will induce Antibiotic
  Resistance and Mercury resistance in bacteria in the mouth and
  Gastrointestinal tract.(58)  
  43. Brain levels of mercury are in a direct linear proportion to the number
  of Surfaces of amalgam fillings in the mouth.(1,19,25)  
  43A? The level of Mercury, in brain tissue of foetus's, new born, and young
  children, is proportional to the number of amalgams in the mother's
  mouth.(61)  
  44. Mercury will cause single strand breaks in DNA.(41,42)  
  45. Mercury levels in the body can not be assessed by either blood or urine
  levels. (26)  
  46. Mercury from amalgam fillings is the single  
  greatest source of dietary mercury for the general population. (W.H.O.
  Criteria 118., 1991).  
  47. Dental personnel are severely effected by exposure to mercury. (3,13,49)
