The hosts address an email from a dentist regarding their previous comments on water fluoridation. While the dentist agrees that excessive fluoride causes fluorosis, she disputes the claim that it causes cavities. Dvorak cites a 2003 study from Kentucky suggesting tooth decay rates increased following mandatory fluoridation, though he acknowledges causation is complex.
The Department of Health and Human Services (HHS) and the EPA have recommended lowering the level of fluoride in drinking water to 0.7 parts per million. The report acknowledges that over-fluoridation can cause dental fluorosis, resulting in brown spots on teeth. Adam Curry asserts that fluoride has historically been used as a pacifying agent and that the new guidelines simply ensure a "guaranteed" dose for the population.
