Fluoride is commonly found in tap water thanks to a process called fluoridation – which the U.S. government has been repeatedly telling us is a safe and effective way to protect teeth from decay, according to Global Research.

But a recent study published in The Lancet, the world's most renowned medical journal, has actually classified fluoride as a neurotoxin – something which has a negative impact on brain development – alongside other extremely toxic compounds such as arsenic, lead and mercury.

A large number of cities within the U.S. are pumping their drinking water systems full of fluoride, and the government is claiming that there are no health risks to this unnecessary practice.

Why is fluoride added to water?

Fluoride is added to water because of an outdated notion that it prevents dental decay, according to Scientific American. If applied frequently in low concentrations, the U.S. is being led to believe that it increases the rate of growth and size of tooth enamel – which helps to reverse the formation of small cavities.

But, modern studies show that dental decay rates are so low in the U.S. that the effects of water fluoridation cannot actually be measured. This means that the benefit of water fluoridation is not clinically relevant, according to Fluoride Alert.
