Dear Sharlene,
We have no evidence (our research group) that H202 causes a release of mercury from dental amalgams. Do remember, H202 exhibits a principal reaction which is, essentially, one of oxidation. Mercury does, without assistance from other substances....sublimate (change directly from a solid to a gas) at a rate dependent upon several factors (e.g. acid concentrations in the oral environment, chemical compounds which act as solvents on the silver/mercury amalgam, etc).
I cannot say, conclusively, that H202 is TOTALLY benign in this regard.....but I have been using it continually, twice daily, over the immediately-past 40 years and have yet to exhibit any signs of mercury toxicity. If one were to use multiple teaspoons of the higher concentrations... circumstances might evolve that would accelerate mercury-release reactions.
However, do understand that one is applying a very small amount of H202, primarily on the front side of of the exposed upper teeth.....not on the very large area of epithelial tissue of the mouth and gums.
I am not recommending that anyone use the higher concentrations of H202, I just outlined the effectivity of such in our experimental research.
The principal insult threat from higher concentrations of H202 manifest in nature as a
danger of "tissue burn" (oxidation) to the skin exposed surfaces....rather than dissolution actions on the silver/mercury amalgam (which is, actually, rather stable chemically).
My apologies for being unable to supply a more simple/conclusive answer to your question, but there are, simply, too many variables possible to allow coverage of all eventualities.
Sincerely, Brooks Bradley.

Mr. Bradley:



Would the higher concentration or for that matter, any concentration of H202

cause a leachng of mercury from amalgams?



Thanks much,

Sharlene
