yes, that is true. it has already been proven that it leaks out and it has already been proven the amounts it takes to affect health are in that range. but, the ADA argues and produces studies that say the amount released is not as high as what all the other studies claim, and therefore they say it doesn't hurt you. they have always been careful to not say amalgams are safe. if they claimed that, they could be liable at some point. still, there are studies comparing those with fillings and those without, nhanes III for instance, which i have already posted. all the bases have been covered by scientists who set out to show the toxicity of mercury fillings. but the government and the ada have been very successful in brainwashing the general public into believing that never happened and that amalgams are safe by continuing to put them in people every single day.
