We should be more concerned about this....
"The first thing you should know is that the
fluoride they put in our drinking water is not a pharmaceutical grade additive.
It is an industrial waste byproduct.
As
aluminum production increased in the first half of the twentieth century, it became necessary to find somewhere to put the fluoride. Manufacturers could no longer dump it into rivers or landfills, because it was poisoning crops and making livestock sick. Francis Frary, chief scientist for ALCOA, had an idea. He commissioned Gerald Cox at the Mellon Institute, to conduct research regarding the benefits of adding fluoride to the water supply.
The Mellon Institute was frequently hired by big business to produce research that supported their industries, and for several decades they produced research showing that asbestos was safe and did not cause cancer. Hmmm.
They also produced reports assuring everyone that fluoride was not toxic and would be beneficial to add to our drinking water for healthy teeth."
