Oh god I'm not getting into this one, again, but I do love the conspiracy angle on the mercury fillings.
I don't think people know how much MONEY the dentists would make, and we are talking capital letter money if there was a real health risk. For a few years all they would need to do is replace the old ones with composite and tadda lots of money to be made.
The lack of mercury in a lot of dental offices these days has nothing to do with health and everything to do with market.
- People are paranoid due to a lot of screwed up information, so they don't want the mercury fillings.
- The composite ones look better.
In terms of longevity the mercury ones are still superior, but in the free market you do what people want, or in places like Germany because its against the law but they don't even allow nickel to be used there which means no steel, based on very weak and mostly rare potentials for allergic reactions, something I've never seen in practice. Ironically I HAVE seen allergies to the composites people are using instead of amalgam fillings.
