Fluoride is neither a nutrient nor essential for healthy teeth and is in virtually all foods and beverages - very high in tea, ocean fish and non-organic grape juice as well as many dental products.  Fluoride should be an individual's choice not a community choice.   51% of the population shouldn't force-feed fluoride to  49% of residents.  And lobbied legislators shouldn't be allowed to prescribed fluoride to every constituent without regard to age, weight, health and need. Without knowledge of total fluoride intake from residents, adding more fluoride to their bodies via the water supply is foolhardy and wasteful at best and deadly at worst.

Consuming a fluoride-free diet does not cause tooth decay.  Rotten diets make rotten teeth and no amount of fluoride has changed that.
