Chan School of Public Health:. But do we need to add it to drinking water so it gets into the bloodstream and potentially into the brain? To answer this, we must establish three research priorities. In particular, we need basic research on animals that would help us understand the mechanisms by which fluoride may be toxic to the developing brain.

If these individuals are at risk, their water must come from a source that is lower in fluoride.

Skip to content Fall In , the Subcommittee on Health Effects of Ingested Fluoride of the National Research Council, part of the National Academy of Sciences, conducted an extensive literature review concerning the association between fluoridated drinking water and increased cancer risk.

The review included data from more than 50 human epidemiologic studies and six animal studies. The Subcommittee concluded that none of the data demonstrated an association between fluoridated drinking water and cancer 6.

A report by the CDC supported these findings. Subsequent interview studies of patients with osteosarcoma and their parents produced conflicting results, but with none showing clear evidence of a causal relationship between fluoride intake and risk of this tumor. Because fluoride naturally accumulates in bone, this method provides a more accurate measure of cumulative fluoride exposure than relying on the memory of study participants or municipal water treatment records.

The analysis showed no difference in bone fluoride levels between people with osteosarcoma and people in a control group who had other malignant bone tumors 7.

More recent population-based studies using cancer registry data found no evidence of an association between fluoride in drinking water and the risk of osteosarcoma or Ewing sarcoma 8 , 9. The information on this page includes details about drinking water quality and safety standards.
