Dental Care Utilization and Oral Health Inequalities

Access to dental care is a vital component of overall health yet remains unevenly distributed across and within nations. Patterns of dental care utilisation reflect a complex interplay of socio-economic status, geographic location, cultural attitudes and health-system design. In high-income countries, insurance schemes can reduce direct costs but do not fully redress gaps in preventive attendance or early intervention. Conversely, in low- and middle-income settings, out-of-pocket payments often deter routine check-ups, precipitating delayed treatment and more invasive procedures. Underutilisation is most marked among marginalised groups—those with lower educational attainment, ethnic minorities and older adults dependent on social care. This inequity manifests both in the prevalence of oral diseases, such as caries and periodontitis, and in the financial strain imposed by catastrophic dental expenditure. Policy initiatives increasingly aim to integrate oral health into universal health coverage frameworks, emphasising preventive services, workforce distribution and community outreach. Effective strategies require multisectoral collaboration, proportionate financial protection measures and culturally attuned health promotion. By addressing upstream determinants—educational opportunity, equitable insurance design and service availability—health systems can narrow oral health disparities and foster more inclusive access to care.
