Fluoride’s Mutagenicity: In vivo Studies
Consistent with dozens of in vitro studies, a number of in vivo studies, in both humans and animals, have found evidence of fluoride-induced genetic damage. In particular, research on humans exposed to high levels of fluoride have found increased levels of “sister chromatid exchange” (SCE). As noted in one study: “In recent years, SCE analysis has […]

Fluoride’s Mutagenicity: In vitro Studies
According to the National Toxicology Program, “the preponderance of evidence” from laboratory “in vitro” studies indicate that fluoride is a mutagenic compound. Many substances which are mutagens, are also carcinogens (i.e. they can cause cancer). As is typical for in vitro studies, the concentrations of fluoride that have generally been tested are far higher (millimolar levels) […]

Water Fluoridation, Tooth Decay, & Poverty
Most of the oral health crises occurring in the United States right now are taking place in low-income urban areas that have been fluoridated for decades. It is unclear, therefore, how fluoridation can be expected to prevent oral health crises in newly fluoridated areas when it has failed to prevent such crises in areas that have been fluoridated for 30 to 60 years.

Fluorine recovery in the fertilizer industry – a review.
The fluorine compounds liberated during the acidulation of phosphate rock in the manufacture of phosphoric acid and fertilizers are now rightly regarded as a menace, and the industry is now obliged to suppress emissions of fluorine-containing vapours to within very low limits in most parts of the world. As with any pollution control operation, it is highly desirable for the operator of the fluorine scrubbing operation to find a use or market for the recovered fluorine to help defray at least partially the cost of the operation.

Acute Fluoride Toxicity from Toothpaste Ingestion
The Food & Drug Administration now requires that all fluoride toothpastes sold in the United States bear the following poison warning: “WARNING: Keep out of reach of children under 6 years of age. If you accidentally swallow more than used for brushing, seek professional help or contact a poison control center immediately.” The FDA warning is […]

Micronucleus and Sister Chromatid Exchange Frequency in Endemic Fluorosis
The rise of sister chromatid exchange (SCE) and micronucleus (MN) in the peripheral blood lymphocytes of the fluorine-intoxicated patients indicates that fluorine is a mutagenic agent which can cause DNA and chromosomal damage.

Luke (2001): Fluoride Deposition in the Aged Human Pineal Gland
This study has added new knowledge on the fate and distribution of fluoride in the body. It has shown for the first time that fluoride readily accumulates in the human pineal gland although there was considerable inter-individual variation

Luke (1997): The Effect of Fluoride on the Physiology of the Pineal Gland (Excerpts)
“The results suggest that fluoride is associated with low circulating levels of melatonin and this leads to an accelerated sexual maturation in female gerbils. The results strengthen the hypothesis that the pineal has a role in pubertal development.”

Fluoride & the Immune System – Summation from the US National Research Council (2006)
“There is no question that fluoride can affect the cells involved in providing immune responses. The question is what proportion, if any, of the population consuming drinking water containing fluoride at 4.0 mg/L on a regular basis will have their immune systems compromised? Not a single epidemiologic study has investigated whether fluoride in the drinking water at 4 mg/L is associated with changes in immune function. Nor has any study examined whether a person with an immunodeficiency disease can tolerate fluoride ingestion from drinking water.”
