(NaturalNews) Fluoride, long added to our drinking water to improve oral health, is probably useless and even harmful to public health.
Its effectiveness is based on shaky science from the 1950s, yet big dental associations around the world keep promoting the addition of fluoride to our drinking water.
“The sad story is that very little has been done in recent years to ensure that fluoridation is still needed [or] to ensure that adverse effects do not happen,” says Dr. Philippe Grandjean, an environmental health researcher and physician at Harvard University.
A little bit of history
In the early 1930s the link was made between fluoride and both mottling – or tooth staining – and stronger, healthier teeth. By the mid-40s the U.S. Public Health Service was convinced that artificial fluoridation of drinking water to 1.0 ppm would provide better oral health without causing mottling from over-fluoridation.
