Five years ago, the city of Calgary gave in to a scientifically illiterate campaign against fluoride in its water supply; five years later, Calgary's grade two children each have an average of 3.8 extra cavities.
A study published in the journal Community Dentistry and Oral Epidemiology shows that Grade 2 students in Calgary had an average of 3.8 more cavities in 2013-14 than they did in 2004-05. In Edmonton (which continued to fluoridate its water), during the same time period, the number of dental caries (or cavities) increased by 2.1, on average.
In other words, ending fluoridation is not the sole reason oral health has deteriorated, but it is a significant factor.
So, why did Calgary city councilors make a decision that has caused a lot of children unnecessary pain and that will cost their parents a good chunk of change in dental bills?
They essentially bought into the unscientific rantings and overblown fears of a small but loud minority of self-centered chemophobes.
Why did Calgary cave to chemophobes over fluoridation?

Ian Bogost writes that the proposed diagnosis reflects a desire to cast negative behaviors as the result of individual mental defects rather than […]
Can an electrified bandage really kill antibiotic-resistant bacteria (and make the wear not as smelly)? Chemical and Engineering News put one, made by Vomaris Innovations, to the test, and the answer seems to be yes. Although the bandage is about a decade old, recent research has shown the technology can destroy hardy, antibiotic-resistant biofilms in […]

It’s good to be proactive, but when it comes to preparing for an emergency situation, one of the most important items you can pack is a flashlight. After all, whatever else you include in your kit won’t be of much use if you can’t see what you’re doing. The Viper 1000-Lumen Tactical Flashlights not only […]
Chances are you took a handful of language classes in high school, and aside from a smattering of conjugations and vocabulary words, the only things you likely remember are the dry, rehearsed sentences that did little to make you speak like a true native. If you’re still hoping to learn a new language but want […]
