Oral diseases are among the most common non-communicable conditions worldwide, yet they often remain overlooked in broader health policy discussions. Dental caries, periodontal disease, and oral cancers contribute significantly to pain, disability, and reduced quality of life across all age groups.

This episode explores:

• The global burden of oral disease• Social gradients in dental health• Fluoride and population-level prevention• Sugar consumption and commercial determinants• Oral health in children and older adults• Integration of dental care within primary health systems• Workforce distribution and access challenges• Oral cancer epidemiology and tobacco exposure• Prevention versus treatment-oriented models

Dental public health illustrates how prevention can dramatically reduce disease burden. Community water fluoridation, sugar reduction policies, and early childhood programmes have transformed oral health outcomes where implemented effectively.

At the same time, inequities in access to dental services highlight broader structural issues - financing models, workforce distribution, and prioritisation within health systems.

Oral health is inseparable from overall health. It reflects both biological processes and policy decisions.
