Calgary's Fluoride Removal: Impacts on Oral Health and Public Policy

The History and Rationale of Water Fluoridation

• 💡 Fluoridation of drinking water began in some U.S. regions to address tooth staining and improve oral health by increasing resistance to decay.
• 🎯 High levels of fluoride in water were found to contribute to better oral health outcomes.

Calgary's Decision to Remove Fluoride

• 📉 In Calgary, Canada, fluoride was removed from the municipal water supply.
• 📊 A study was conducted to assess the downstream impacts of this removal, comparing Calgary with Edmonton, which maintained fluoridation.

Findings on Tooth Decay Rates

• ⚠️ In Calgary, after fluoride removal, 65% of children experienced tooth decay.
• 📈 This indicates a significant increase in dental issues following the cessation of water fluoridation.

Reinstatement and Public Health Considerations

• 🗳️ A decade after removal, Calgary voters decided to reinstate fluoride in the water supply.
• 💬 The discussion around fluoridation often overlooks the consequences of removal and the need for alternative public health strategies to prevent tooth decay.
• 🛠️ Preventing tooth decay, which is common, painful, and entirely preventable, should be a societal priority, requiring adequate public resources.
