1. We know that topic fluoride usage increased resistance to caries. 2. It is kind of difficult to consume fluorinated water without exposing your teeth topically to the fluoride. 3. Ingesting fluorine is definitely not good for you and recent studies seem to confirm this. So, it seems to me that while fluorinating drinking water would incidentally topically expose teeth to its beneficial effects, we don't really need to fluorinate our drinking water as there are other ways to expose teeth topically to fluorine that don't involve drinking fluorinated water. And no, fluorinating water was not a good decision because of the cautionary principle. Even from the beginning, they knew that the effects came from topical exposure, adding it to drinking water was reckless. But hell, this was the time where we added lead to gasoline.
