Or magnesium chloride and hydrogen peroxide with much better results, and it's not at all toxic. The peroxide even replaces chlorine with better pathogen killing results.
Sorry, but there has only been one peer reviewed study in all the years that floridation has been done that showed any statistical link between floride and any health problems, and when that group tried the same analysis in a different location they could not replicate those initial findings, so they did find what appeared to be a rare cancer risk with the water in the original study location, but as the second attempt at it showed, that link had nothing to do with Floride.
Floridation in drinking water as a major public health risk is garbage sciense, its same level of BS as Global Warming.
Floridation is not done for PATHOGEN killing... its done to fight tooth decay. You chlorinate water for pathogens, that has nothing to do with why Floride is added to water.
