The City of Calgary reintroduced fluoride into the drinking water system today, joining other Alberta municipalities including Edmonton, Lethbridge and Red Deer that already fluoridate their water.
To protect public health, The City will be adding fluoride to achieve the 0.7 milligrams per liter (mg/L) as recommended by Health Canada to enhance oral health. The reintroduction of fluoride has no impact on the taste or smell of drinking water.
Fluoridation is backed by the Public Health Agency of Canada, Alberta Health Services and numerous health organizations worldwide. It is a proven, safe and cost-effective way to reduce cavities and improve dental health, especially for those without regular access to dental care.
Fluoride was first introduced into Calgary’s drinking water in 1991. Our drinking water remained fluoridated for 20 years until City Council directed Administration to discontinue the practice in 2011. The Council decision to reintroduce fluoride in the drinking water system was made one month after a plebiscite in the 2021 Civic General Election found 62 per cent support for fluoridation amongst voters.
