Because fluoride reduces numbers of teeth cavities does not mean fluoride is good for overall human health. Health authorities need to spell this out.
Physicist Fritjof Capra, and others before him, warned in the 1980s that science was at risk of misinterpretation by being compartmentalised or reductionist. An example of reductionism operating in the discussion of human health and tooth cavities is that the Australian Aborigines and other tribal people worldwide, at first contact, generally had healthier teeth than western people. The fluoride debate is therefore not just about the risk of adding another poison to the water supply; it is about the extent to which humans are refusing to eat foods suited to human health.
Excessive animal proteins, excessive grains that are primarily acidic in the body, and de-natured, processed foods, which is a lot of what western-culture people eat, can be reasonably considered to reflect in tooth decay.
It is science that has contributed to the production of fluoride in quantity, and to recognition that fluoride reduces dental caries. However, it is superstition that thinks it reasonable to excessively eat foods not ideal for humans, then dose with fluoride in a piecemeal (non-holistic) attempt to fix symptoms of deteriorated health.
