So why do teeth experts have the final say on whether we put heavy metal, nuclear waste products in our tap water?<p>Perhaps the concern isn't the 2% dental improvement, maybe that's just a red herring. Perhaps an actual toxicological study would be more appropriate.<p>I know that some water sources have naturally occurring fluoride, which is often used as an excuse or ad hoc justification for it's efficacy, but that's just fuzzy, wishful thinking.<p>Also the fluoride they put in the water is not derived naturally, but instead is largely the result of nuclear waste byproducts that, if they didn't put in the water, they'd have to pay to dispose of safety, so let's not forget the massive conflict of interest in studies like this to find any excuse to keep up the status quo.<p>The act of avoiding the cost of safe and responsible cleanup by simply injecting a small amount of poison into the food or water supply is fairly common practice, and if regulatory agencies had any actual interest in public or environmental health, that'd likely be one of the first things to legislate on.<p>So yeah, nice try, but no thanks.
