In brief
In a significant public health shift, Calgary has brought back fluoride to its drinking water supply after over a decade. Initially removed in 2011 due to cost concerns, the reintroduction follows alarming reports of deteriorating oral health in the community, particularly among the youth.
Calgary, June 30, 2025 — Residents can now expect a familiar but rejuvenated element in their drinking water as Calgary, a Canadian city, has reinstated fluoride in its water supply starting Monday. The mineral, recognized for its dental health benefits, is believed to strengthen tooth enamel and reduce decay. The city's decision to eliminate fluoride from the water in 2011 was based on calculations that deemed the expense of treating water with the mineral outweighed its benefits. However, the pressures from community members advocating for its return, alongside concerning trends in children's oral health, prompted the local authorities to reconsider. “There’s no question that it reduces cavities, which is not just a cosmetic issue, because poor dental health is associated with poor body health,” stated Joe Schwarcz, a chemistry professor from McGill University and director of a program dedicated to dispelling scientific misinformation.Fluoridation is celebrated globally as one of the most impactful public health measures of the past century. Nevertheless, it has historically faced resistance, with some detractors viewing it skeptically. Mistrust surrounding fluoride has roots dating back to the 1950s when it was controversially labeled a mind-controlling substance in politically charged narratives.As Calgary re-embraces fluoridation, public health advocates hope this decision will lead to improved dental outcomes among its young population, reflecting a renewed commitment to community health and well-being.
