Just three years after the city of
Calgary stopped adding fluoride to its drinking supply, a study conducted by the University of Calgary found that children had double the amount of tooth decay than in the neighboring city of Edmonton which continued to fluoridate. Both cities are
in the western province of Alberta, Canada.
Calgary’s city council decided to stop adding fluoride in 2011 partly
because it would have cost $10 million to improve the system and
maintenance would have cost one million dollars annually. There was also protest by chemo-phobes who claimed that fluoride was a poisonous mineral that, while naturally occurring, should not be increased to the levels that would provide dental benefits.
The fact that Edmonton, in the same province, continued to add the
chemical gave researchers a good opportunity to study the effects on
cavities. They studied 5,000 Grade 2 students, usually around seven
years old and still with baby teeth. After just three years, those in Calgary had double the tooth decay
that they had when water was still fluoridated, and double the amount in Edmonton. An author of the study, Professor Steven Patterson, a professor of dentistry at the University of Alberta, said, “It was a bit of a surprise to see that kind of difference so soon
and see it significantly between the two communities.”
The
study was designed to insure that fluoride was the factor that made the
difference. I certainly believe it does.
And in case you were wondering, fluoride is poisonous...in the same way salt is poisonous. Keep drinking fluoridated water.
