Community water fluoridation policy and population oral health: a policy analysis

Dental caries (tooth decay) remains the most common noncommunicable disease worldwide and continues to impose significant dental and systemic health and economic burdens despite being largely preventable. Untreated disease contributes to pain, infection, reduced quality of life, and increased demand for restorative dental care. Governments, therefore, face policy decisions regarding population-level prevention strategies. This analysis evaluates policy options related to population-level fluoride exposure, including maintaining existing community water fluoridation (CWF) programs, expanding fluoridation coverage, discontinuing fluoridation in favor of clinical prevention strategies, and implementing alternative delivery mechanisms such as salt fluoridation. Drawing on Bardach's Eightfold Path for policy analysis, options are assessed using public health policy criteria, including health impact, equity implications, economic considerations, safety, and implementation feasibility. Evidence shows that CWF can reduce caries prevalence and treatment needs at the population level, particularly in communities with limited access to preventive dental care. Economic evaluations indicate that fluoridation reduces expenditures associated with dental treatment. However, policy feasibility varies depending on infrastructure, governance systems, and public health capacity. For policymakers, fluoridation represents one component of broader health prevention strategies that combine population-level prevention with improved access to preventive services.
