Fluoridation of Drinking Water

Fluoridation of Drinking Water

About 87 per cent of Tasmanians receive mains water supply from TasWater. Of this serviced population, about 97 per cent of those people receive a fluoridated supply.

Fluoridation of water supplies is a public health measure that aims to replicate the benefits of reduced dental decay obtained where optimum concentrations of fluoride occur naturally. It involves the controlled adjustment of a fluoride compound to a public water supply in order to bring the fluoride concentration up to a level that effectively prevents tooth decay.

Water fluoridation is supported by the Department and has been endorsed as a safe and effective public health measure by more than 150 scientists and health organisations, including the:

The Department has issued a Tasmanian Code of Practice for the Fluoridation of Public Water Supplies, which is based on the legislative requirements under the Fluoridation Act 1968 and the Fluoridation (interim) Regulations 2009. The legislative framework establishes a Fluoridation Committee that advises the Minister for Health on matters relating to fluoride and public health. The Committee comprises members from within the Department and external.

The Code of practice can be found at:

The water supply in Beaconsfield was the first fluoridated supply in Australia in 1953.

Each year the Fluoridation Committee published a Report for the Minister of Health detailing monitoring and management activities for fluoridated water supplies.  The Director fo Public Health publishes this information annually
