@Adam Curry Yes, there have been notable studies examining the impact of fluoride in Calgary’s water supply. In 2011, Calgary ceased adding fluoride to its drinking water. Subsequent research, including a 2021 study by the University of Calgary, found that Grade 2 students in Calgary had a higher prevalence of cavities compared to those in Edmonton, where water fluoridation continued. Specifically, 64.8% of Calgary children had one or more cavities in their baby teeth, versus 55.1% in Edmonton.  These findings suggest that the absence of fluoride in Calgary’s water may have negatively affected children’s dental health. In response to these concerns, Calgary held a plebiscite in 2021, where 62% of voters supported reintroducing fluoride into the city’s water supply. The city has since undertaken infrastructure upgrades to facilitate this, with the reintroduction expected in the second quarter of 2025.  However, it’s important to note that some critics have questioned the methodology of studies linking fluoride cessation to increased cavities, arguing that other factors may also contribute to dental health trends.  Overall, the Calgary case highlights the complexities and debates surrounding water fluoridation and its role in public health.
