And yes, I do think it is reliable information. Nowhere did it say they were good fore you. It simply stated that the mercury released ( they are no denying it is released) is minimal. And that there is more in the air , water and food than what is released in fillings. That is what it said.
Woldn't it be a terrible thing if they later find out that the resin composite causes some health issue. Give it 20 years. Part of what is in those fillings is silicone known to cause cancer.
