Increased tooth decay found in Calgary children linked to fluoride cessation: Study

Dec 19 2017, 11:07 am

A recent University of Calgary study found an increase in Calgary children’s tooth decay likely due to fluoride cessation in our drinking water.

On Thursday, May 19, 2011 The City of Calgary Water Services officially discontinued the practice of fluoridating Calgary’s drinking water. The order was carried out with the authorization from Council and the official receipt of Alberta Environment.

The study examined the short-term impact of ending fluoridation in drinking water. Researchers specifically looked at Grade 2 children in Calgary, where fluoridation has stopped, and Edmonton, where fluoridation continues.

Results found that both cities actually had an increase in children’s primary tooth decay, but Calgary’s magnitude of the increase was greater than in Edmonton. Another trend found was for permanent teeth indicating there may be adverse effects too.

Future steps of the study include continuing data collection efforts in the both Calgary and Edmonton.

Fluoride is found naturally in the Bow and Elbow Rivers, with varying concentration levels. So, although we are getting fluoride from other sources, and it is easily accessible for purchase, it may just not be enough.
