The Province of Ontario, Canada has decided to lower the levels of fluoride added to water via fluoridation programs. The decision, dated September 20, 2000, lowers the recommended level of fluoride in water from 1.0 to 1.2 parts per million to 0.5 to 0.8 parts per million. While the initial proposal was to lower the levels to 0.8 to 1.0 ppm, after further analysis the Ontario’s Ministry of the Environment decided to lower them even further. According to the Ministry of the Environment, “excessive levels of fluoride in drinking water [1.5 ppm] may lead to dental and/or skeletal fluorosis unless steps are taken to reduce overall fluoride exposure.”
