GENEVA, Switzerland: “A happy mouth is a happy body,” FDI World Dental Federation said on World Oral Health Day (WOHD). Celebrated annually on 20 March, WOHD aims to advance oral health globally through the sharing of knowledge as a tool of empowerment. FDI’s message for this year is shared in a video that brings together voices from governments, the private sector and advocacy organisations for chronic health conditions. The initiative underscores the urgent need for collective action to ensure universal access to oral healthcare and to support systemic health worldwide.
