Water fluoridation in Australia effectively prevents tooth decay and reduces socioeconomic disparities in dental health. While concerns about dental fluorosis exist, community water fluoridation remains a safe and equitable public health measure.

Area of Science:

  • Public Health
  • Epidemiology
  • Dental Research

Background:

  • Water fluoridation is implemented in Australia, reaching nearly two-thirds of the population.
  • Public understanding and support for water fluoridation are declining despite scientific evidence.
  • Recent reviews reaffirm the safety and effectiveness of water fluoridation.

Purpose of the Study:

  • To review the rationale, context, and support for water fluoridation in Australia.
  • To examine current Australian evidence on caries prevention and dental fluorosis trends.
  • To assess the effectiveness and social equity of water fluoridation.

Main Methods:

  • Review of Australian epidemiological studies and oral health data.
  • Analysis of evidence on caries-preventive effects and dental fluorosis prevalence.

  • Examination of socioeconomic impact on caries reduction.
  • Main Results:

    • Consistent evidence supports water fluoridation's effectiveness in caries prevention.
    • Lifetime exposure to fluoridation shows significant reductions in decayed, missing, and filled surfaces (DMFS).
    • Water fluoridation reduces socioeconomic inequalities in caries prevalence.

    Conclusions:

    • Community water fluoridation is the most effective and equitable measure for caries prevention.
    • Increased dental fluorosis prevalence necessitates a review of overall fluoride exposure.
    • Targeted strategies are being implemented to optimize the benefit-risk balance of fluoride exposure, especially for preschool children.
