Portland, I love you, but you’re bringing me down:
Late last night, Portlanders rejected a plan to fluoridate their city’s water supply (and the water of over a dozen other cities). It’s the fourth time Portland has rejected the public health measure since 1956. It’s the fourth time they’ve gotten the science wrong.
When new medical treatments are implemented, when new drugs are introduced into the populace, there is always some hesitation. There are (hopefully) some clinical trials to back up the new intervention, but the long-term implications are often unclear. Water fluoridation doesn’t have this problem. For over 65 years, it has been rigorously tested as a public health measure, and considered one of the most successful measures of the last 100 years, alongside others like recognizing that tobacco use is a health hazard.
Simply put, the refusal of water fluoridation doesn’t have any scientific support. A review on fluoride’s effect on IQ out of Harvard was waved about as the main scientific opposition, but has since been thoroughly refuted. Decades of studies in different cities in different states, involving millions of people, have concluded that there is a safe level of fluoride—one part-per-million—that can be added to water for enormous benefit to our teeth and oral health with little to no adverse effects.
Does anybody understand the politics of this?
