The allowance by the European Union for 1.5ppm natural fluoride in public drinking water is understandable since natural fluoride, typically from calcium fluoride soil deposits, is always accompanied with plentiful calcium from other calcium salts. This helps minimize the assimilation of fluoride into the bloodstream after ingestion. (The U.S. also allows 2 ppm for natural fluoride).
However, no allowance should be made to intentionally add synthetic industrial fluoride into any human drinking water supply. The U.S. Health and Human Services lowered the allowed added fluoride level from 1 down to 0.7 ppm, in an attempt to mitigate the extremely high incidence here of permanent dental fluorosis, an abnormal enamel hypoplasia. The fact that 1.5 ppm may exist in some natural waters does not provide an excuse to “fill ‘er up” near this level artificially when drinking water is naturally low in fluoride. Adding industrial fluosilicic acid into water to dissociate into fluoride and silicic acid increases the blood level of fluoride in consumers at any given calcium level in the water and increases the incidence of dental fluorosis for any treated city. There are no exceptions. Soft water regions will have populations with elevated blood fluoride at any fluoride added level, compared to hard water regions.
The open-ended allowance to add 1 ppm fluoride regardless of other characteristics in the water fails to understand that the toxicity of fluoride is dependent on the specific environment in which the fluoride is dissolved. Calcium is the antidote to fluoride oral poisoning because calcium inhibits assimilation of fluoride. Moreover, calcium fluoride is not a listed poison on poisons registries with its very high LD50 (3,000 mg/kg), while all synthetic industrial fluorides are fully water soluble and are all listed poisons on poisons registries because of high assimilation after ingestion and a low LD50 (65 mg/kg).
Assimilated fluoride from a typical water system with 1 ppm fluoridated water leads to blood levels around 0.1 ppm which causes accumulation of fluoride into bone. After years of exposure, bone fluoride levels accumulate to cause bone and joint pain and bone weakening. The process begins with the first sip and continues from there on. Fluoride converts normal bone hydroxyapatite into abnormal fluoroapatite which is not resorbed properly by parathyroid hormone, so calcium homeostasis is altered. This causes the formation of reabsorption of remaining bone coupled with formation of new bone but of poor quality. The conversion of normal bone into fluoride loaded bone has now been documented in man and animals with detailed scanning electron microcopy work that indicates that fluoridated bone has an altered density and that fluoride accumulation is accompanied with bone thickening and eventually external irregular formations or exostoses. Most people eventually accumulate fluoride in bone to about 3-4,000 mg/kg lifetime where bone pain is typical. Fluoride does not belong in bone, so bone weakening occurs at virtually any accumulated amount. Although the National Research Council 2006 Report on Fluoride in Drinking Water (National Academies Press, Washington, D.C.) states that bone pain begins around 4,000 mg/kg, the tabulated data used to generate this claim includes published findings of bone pain at far lower bone fluoride levels, around 1700 mg/kg. It is certain that people have widely differing individual sensitivities to fluoride accumulation.
The U.S. Food and Drug Administration has never approved fluoride for consumption. The FDA in 1963 ruled that fluoride added into water intentionally is an uncontrolled use of an unapproved drug, ruled in 1975 that fluoride is unsafe to add to foods, and ruled that fluoridated water cannot be used in kidney dialysis wards due to increased morbidity when so used. In 1966, the FDA banned the sale of all fluoride compounds intended for ingestion by pregnant women in the U.S.
Although the U.S. Health and Human Services currently allows added fluoride to 0.7 ppm, don’t let this information fool you into thinking that Americans agree with the practice. Most people in the U.S. understand that fluoride is a calcium chelator and thus a harmful substance and drink bottled water, or treat water at points of use with reverse osmosis, to avoid the bone accumulation and other adverse sequelae.

I hereby formally apologize to the European Union, and especially to the Republic of Ireland where fluoride is mandatory, for any and all U.S. officials who initially recommended the use of fluoride in water supplies for human consumption.
The procedure does not reduce dental decay, is harmful to many physiologic systems especially thyroid, the developing brain, and bone, and is an expensive waste of funds. Treating any human with fluoride as though it were an approved oral ingestible dental prophylactic, without a prescription and without monitoring its effectiveness in an individual patient, is a violation of medical ethics and is not only immoral but is an act of violence committed on the trusting public.
Please consider this information when writing any policy governing the intentional addition of synthetic fluoride compounds into public water supplies.
