Fluoridation

Fluoride is naturally found in all water sources, including fresh and sea water. Fluoride is also found naturally in a wide range of food items including tea, fish and rice. When present in drinking water at the optimum level, or used in dental treatments, fluoride can promote dental health by helping to prevent tooth damage and decay. It has also been shown that when added to drinking water supplies, fluoride can promote dental health by helping to prevent tooth decay.

For further information on fluoride and fluoridated drinking water, please refer to the following factsheets:

Fluoridation publications

• The State Oral Health Plan 2016–2020 was published by the Department of Health in 2016 and is accessible via the Chief Dental Office page.
• Fluoride use for oral health in Western Australia 2020 (PDF 161KB) is also available for download.

The study Water Fluoridation and Dental Health of Children in WA was published by the Department of Health in 2016. This study analysed both the frequency and extent of tooth decay in fluoridated and unfluoridated areas of WA, for both deciduous and permanent teeth. It revealed that children from unfluoridated areas in the South West of Western Australia were at greater risk of having a worse tooth decay experience, compared with children from the fluoridated Perth metropolitan area. The peer-reviewed report Oral health of school children in Western Australia (external site), published in the Australian Dental Journal in 2016, also made a similar finding.
