text: Steven, I give you the proper terminology and can list for you 154 peer reviewed studies dating back to 1942. You obfuscate and refer to 154 peer reviewed studies as an "irrelevant mess" .  Your cognitive dissonance is extremely strong or you simply choose to lie.  Typical lobbyist attempt to discredit every thing opposing your talking points. 
  
  All synthetic fluorides are toxic, and naturally occurring calcium fluoride is benign in comparison (in trace amounts of course, since too much of a good thing is no longer a good thing).  Sodium fluoride is the most expensive synthetic fluoride, and is used the least in U.S. water supplies. The other two more toxic types are used the most in the U.S. water, which should not surprise anyone that they are also the cheapest. Even though sodium fluoride is the least toxic synthetic fluoride, this type has been studied extensively, and associated with many adverse health problems. 
  
  Remember Steven, 154 peer reviewed studies, 154 since 1942.
