This marks the second year of the 2024‒2026 campaign, “A HAPPY MOUTH IS…”, which aims to inspire lasting and positive change by educating people on the crucial role a healthy mouth plays in our lives.

With this concise yet impactful tagline, FDI hopes to simplify oral health and make it accessible explaining the benefits upfront in a plain-speaking way without relying on additional explanation.

From the mouth-body connection to the mouth-mind connection

Each year of the 3-year campaign focuses on a specific theme that aligns with global health developments, particularly following the adoption of WHO’s Oral Health Resolution in 2021.

In 2024, the theme was “A HAPPY MOUTH IS A HAPPY BODY,” highlighting the strong connection between oral health and general health.

In 2025, the focus shifts to the mouth-mind connection, with the tagline “A HAPPY MOUTH IS… A HAPPY MIND.”

This campaign aims to raise awareness of how poor oral health can negatively impact quality of life, highlighting the importance of a healthy mouth for mental well-being.

The campaign will emphasize for example how maintaining a healthy mouth can contribute to overall happiness because your mouth, body, and mind are all interconnected, and caring for your teeth and gums can significantly improve your overall well-being.

In fact, a healthy mouth can boost your positivity, self-esteem, and confidence, ultimately enhancing your quality of life. On the other hand, poor oral health can make it difficult to socialize, limit your food choices, and lead to stress and anxiety—all of which are essential for a happy mind.

A movie inspired campaign: set to the rhythm of a beat

Last year, Toothie, FDI's beloved beaver mascot, starred in an engaging movie-themed campaign.

For 2025, Toothie returns in a new campaign set to the rhythm of a beat, with music playing a central role in campaign activities. The goal? To make everyone smile—inside and out!

This new creative approach is designed to captivate diverse audiences and continue the campaign's broad-reaching impact, encouraging people to prioritize their oral health and join in celebrating World Oral Health Day.
