But this is more like suddenly insisting that everyone's watches have radium in their dials like the 50's.  

We know more than we used to about what improves child dental health with least risk to the general population.  Most of the developed world has abandoned indiscriminate systemic dosage via water fluoridation, and the World Health Organization has reported that in developed nations, systemic fluoride dosing has no correlation to dental health. 

Port Angeles was fine with unfluoridated water until 2006, when a City Council that did many questionable things did one more, and without public notice signed a no-escape ten-year contract to add industrial fluoride compounds to our municipal water supply.  

At the end of the ten years, the current Council first proposed an advisory vote, then decided on a survey of all water customers, including those outside the City limits.  Two-thirds of them said "No" to fluoride  --  and the city overruled them.  This is not tin-hat nonsense.
