Introduction

Understanding the Global Importance of Oral Health

Oral health affects much more than the teeth and gums. It can influence comfort, nutrition, communication, confidence and quality of life. Oral diseases also remain common across many age groups, making prevention, early recognition and access to professional dental care important public health priorities.

This resource brings together important oral health statistics and research findings in one structured guide. The sections are organized to help patients, caregivers, educators, journalists and health-conscious readers understand the scale of common oral health conditions and the factors associated with them.

Throughout this page, statistics are presented with context. Prevalence estimates may differ between studies because of variations in population, location, diagnostic criteria, age range, study design and data collection methods. For that reason, figures should be interpreted as evidence-informed estimates rather than universal values for every individual or country.
