Campaign theme: 2024-2026
Our next 3-year campaign starts now! “A HAPPY MOUTH IS…” offers a simple yet powerful way to capture the multifaceted nature of oral health in a concise and relatable manner. The 2026 campaign Highlights the essential role oral health
plays in overall well-being throughout life, from infancy through older adulthood. By promoting healthy habits and regular care at every stage of life, we empower people to smile, eat, speak, and live with confidence— because a HAPPY MOUTH IS...A HAPPY LIFE.
What is World Oral Health Day?
On the 20 March every year, we ask the world to unite to help reduce the burden of oral diseases, which affect individuals, health systems and economies everywhere.
Its purpose: to empower people with the knowledge, tools and confidence to secure good oral health.
