Fluoride (the ionic form of fluorine) is a trace mineral in the body – meaning it has necessary, beneficial functions in trace amounts from foods. viz. it protects teeth from decay, hardens tooth enamel and strengthens bones.

Natural food / drink sources of fluoride  – include tea, fish;

Water fluoridation is a farce and also harmful.  

• Toxic, non-food forms of fluoride (e.g. hydrofluorosilic fluoride – a waste product from fertilizer plants) are added to municipal drinking water and toothpaste mainly for the purpose of protecting and strengthening teeth – but not only is this practice causing many health problems, it is not even benefiting our teeth! A New Zealand study found no difference in tooth decay between fluoridated and non-fluoridated water areas. Many European countries have stopped fluoridating.
• Fluoridation has been linked to tooth discoloration, hip fractures, bone cancer, lowered intelligence, and kidney toxicity, plus is a cause of goiter in dogs.   Fluoride is more toxic when there is an iodine deficiency. A 2002 study found that 67% of Americans live in communities with fluoridated water. In humans, effects on thyroid function were associated with fluoride exposures of 0.05-0.13 mg/kg/day (when iodine intake was adequate) and 0.01-0.03 mg/kg/day (when iodine intake was inadequate).”
