Fluoridation, per se, has been vastly overrated in regard both to what was promised for it in the early days and also now, after we have had a fair chance to see what it might be doing. There are valid and significant objections to fluoridation. No one has any idea of what the possible undesirable effects are of fluoride ion on the human body. Thus it is not possible to say that fluoridation, is "absolutely safe." Until more knowledge is available about the total fluoride ion intake from all sources, the measurement of such intake and its specific effects, fluoridation of commercial drinking water supplies is definitely to be opposed.
