“Just because we did studies over the last 70 years, it doesn’t mean that we did everything that is necessary to know for sure that fluoridation is not toxic to some processes in the body or development of the brain. Those studies have actually not been done,”

Exactly. the official studies have never been done. And all other non official studies are starting to show that fluoridation is BAD. Not only that, the real history of why fluoridation started and what the toxic crap actually is, is becoming more generally accepted. I do love how more and more peer reviewed academics are now coming forward to condemn flouride.
