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
Several areas of Queensland, such as Julia Creek, Quilpie, Thargomindah and Adavale are known to have naturally occurring fluoride present in their drinking water, a characteristic that has been studied since the late 1920s.
