Water fluoridation
Health and dental organizations worldwide have endorsed its safety and effectiveness. Its use began in 1945, following studies of children in a region where higher levels of fluoride occur naturally in the water. Further research showed that moderate fluoridation prevents tooth decay.
Water fluoridation in Australia
Approximately 95% of the population has access to fluoridated water (September 2011). Fluoridation commenced in New South Wales with Yass in 1956, with Sydney fluoridating in 1968. The use of fluoride is regulated by the Fluoridation of Public Water Supplies Act 1957, and the Fluoridation of Public Water Supplies Regulation 2007.
