Constituting Global Oral Health: Toward a Policy-Relevant and Action-Oriented Science

Despite its significant global burden, oral health continues to be excluded from global health systems, policies and discourse. This exclusion reflects more than institutional neglect; it reflects entrenched structural, epistemic and professional dynamics that have marginalised oral health both externally and internally. This commentary makes the case for constituting global oral health as a distinct science and action discipline. Grounded in dental public health and oral epidemiology but extending beyond them, global oral health needs to address transnational determinants, apply systems thinking and pursue equity through a decolonial lens. We advance four core arguments: that the field lacks a coherent scientific identity; that building a functional discipline requires strategic, epistemic and institutional alignment; that oral health's exclusion is reinforced by both global health structures and professional self-isolation; and that a distinct disciplinary identity is essential for systemic integration and relevance. A comparative delineation and a working definition help clarify the scope of this reconfigured field. Moving beyond symbolic inclusion requires building an intellectually grounded, politically conscious and structurally engaged discipline capable of actively shaping the future of global oral health.
