Editorial: Oral Health: luxury or a fundamental human right? The necessity of introducing a dedicated oral health budget and Proportionate Universalism in Greece.

Oral health is an integral part of overall health and critically affects quality of life as well as personal and social well-being. Poor oral health negatively influences general health and creates medical, financial and social burdens for individuals, families and health systems. The US Office of Disease Prevention and Health Promotion (2021) sees use of the oral health care system as a leading health indicator. Oral health improvement is an important step to reduce socioeconomic inequalities and promote the UN Sustainable Development Strategy (Wang et al., 2020, Huang and Chang 2022). Moreover, "achieving the highest attainable standard of oral health is a fundamental human right of every human being" (WHO 2022a).
