Socioeconomic Influences on Oral Health Outcomes
Summary
Oral health is inextricably linked to socioeconomic position, encompassing education, income and occupation. Individuals in lower socioeconomic strata experience higher rates of tooth decay, periodontal disease and tooth loss, driven by material deprivation, limited access to preventive and restorative services, psychosocial stressors and suboptimal health behaviours. Early-life socioeconomic disadvantage can set a trajectory of cumulative risk, as nutritional deficits, exposure to cariogenic environments and restricted care reinforce one another over the life course. Conversely, higher educational attainment and stable income facilitate health literacy, regular dental visits and adoption of protective habits such as daily brushing and interdental cleaning. These patterns manifest globally, with marked disparities between and within countries, reflecting differences in health systems, social safety nets and cultural norms. Interventions that target upstream determinants—improving education, reducing poverty and integrating oral health into universal health coverage—offer the most sustainable means to redress inequities. A life-course perspective highlights windows of opportunity in childhood, adolescence and older age, emphasising that policy action at multiple stages is needed to narrow the gap in oral health outcomes.
