This study explores the relationship between healthy eating habits and the prevention of dental caries among children in the European Union. Drawing on statistical data from the WHO, Eurostat, and national health reports, a comparative analysis is conducted to evaluate the prevalence of dental caries in relation to nutrition policies, educational interventions, and access to dental care services. Case studies from Romania, Sweden, France, Germany, and Spain are examined to highlight best practices in caries prevention, including school-based health programs, fiscal regulations that promote healthier food choices, and community-level initiatives that engage families and local institutions. The findings underscore the importance of integrated public policies that combine nutrition education, health-oriented taxation, free and equitable access to dental services, and strong involvement from local governments and stakeholders. Romania demonstrates significant potential for improvement through the expansion of current programs and the development of a consistent and effective legislative framework. The study proposes a transferable intervention model that can be adapted and implemented across EU member states, along with tailored policy recommendations specifically designed for the Romanian context. Ultimately, the research highlights the importance of collaborative efforts among the health, education, and policy sectors to address oral health disparities and develop long-term, sustainable prevention strategies for children across Europe.
