It is an unavoidable fact that ageing leads to a decline in the physical and mental functions needed for daily living, as well as increasing vulnerability to disease. In the oral cavity, loss of teeth and decline of oral functions such as chewing and swallowing also often occur. In this context, including the coverage of dental care in universal health care regimes is an urgent challenge in the global ageing society. In 2015, the FDI World Dental Federation launched the Oral Health for an Ageing Population (OHAP) project to expand the role of oral health professionals in achieving healthy longevity. In the OHAP Season II project (2021–2024), we developed a web app to help dental professionals assess the physical/mental status and oral frailty risk-level of older patients, along with an Oral Exercise Brochure to help older patients maintain their oral health and prevent oral functional decline. The OHAP Season III project (2024–2027) started in June 2024. The focus of this session is to share the plan and expected outcome of this phase, and to build global momentum for the promotion of oral health in older people.
