For Indigenous communities, such as Aboriginal Australians, Māori, and those in the Global South, oral health disparities stem from historical and ongoing structural violence, socioeconomic barriers, and limited access to culturally appropriate care. The authors argue for a decolonisation framework in global oral health that shifts power, accountability, and respect toward Indigenous and marginalised communities. A rights-based, accountability-informed decolonisation framework seeks to address historical and ongoing oral health inequities, integrating a view that oral health is a human right and demands that governments and health systems rectify the disparities. It emphasises culturally relevant care and inclusive policymaking, fostering solidarity and systemic change to create equitable and effective oral healthcare for all populations. We propose that deliberate actions need to be taken to centre power redistribution, accountability, and respect in global oral health, moving away from Euro-American-centric frameworks to create an equitable, culturally responsive oral healthcare system. Our calls to action include the need for self-reflection within the field to dismantle entrenched colonial ideologies and prioritise Indigenous leadership and knowledge. Effective allyship should involve collaboration driven by the needs of communities, with institutions accountable for reducing exclusionary practices.
