Calgary Reinstates Fluoride in Water Following Community Outcry
In an effort to combat declining dental health among children, Calgary resumes the addition of fluoride to its drinking water supply.
Starting Monday, residents in Calgary, located in Western Canada, will find fluoride once again flowing through their taps. The reintroduction comes following a significant push from the community and troubling studies indicating a decline in children's dental health since the city opted to eliminate fluoride from its water in 2011. Originally, the city concluded that the costs of fluoridation surpassed the potential benefits, but growing data highlighted the need to support children’s oral health more effectively.
“Fluoride has demonstrated its ability to reduce cavities, which is essential as poor dental health can lead to broader health issues,” noted Joe Schwarcz, a chemistry professor at McGill University and an advocate for scientific clarity. This decision marks a return to one of public health's most acclaimed innovations, despite longstanding skepticism rooted in conspiracy theories and misinformation surrounding fluoride.
While the city aims to restore dental health among young residents, the debate over fluoridation continues amid public health discussions. The Calgary city officials are hopeful that the return of fluoride will help mitigate the troubling trends in cavity rates and overall oral health among children, while weighing the economic implications of this public health measure.
