When your half right your half wrong.Blah
You cant trust the government.
People have different sensitivities to mercury,different removal rates,different exposures.
The government doesnt do studies on mercury because they fear the results. 300 years of tests have shown it to be a biocide and neurotoxin. A mouth full of Amalgams cause exposures that are in the unsafe range.
But you are correct that Amalgams are not the cause of all problems.
