The oral health of people with intellectual and developmental disability is poorer than that of the general community. Any solution for people with intellectual and developmental disability living in residential services needs to include disability support workers (DSWs). Previous studies have used either didactic or train-the-trainer approaches to enhance DSW knowledge and skills. Taking a different approach, a novel program used DSWs as embedded oral health champions. This model provided educational opportunities for DSWs to learn about good oral health and then share with peers and provide benefits to people with intellectual and developmental disability that they support. Interviews with a sample of these champions were conducted and analysed using content analysis. Findings suggest that DSWs are capable of affecting change with the right type and depth of training, management and organisational support. A DSW-led champions model has merit, however requires ongoing expert support to help maintain and sustain benefits over time.
