In the third episode of Series 2 of Oral Health Matters, host Richard Watt, Professor of Dental Public Health at University College London, is joined by two leading legal and health researchers to discuss the intersection of international law and dental health. This conversation explores the shift from viewing health as an abstract value to a body of binding national and international standards that frame oral health as a fundamental human right.

As global health agendas increasingly prioritize equity, this episode examines whether a country can truly achieve universal health coverage if oral health remains excluded or relegated to the private sector. Our guests provide a deep dive into the legal obligations of states to "respect, protect, and fulfil" the right to health, the impact of commercial determinants, and how human rights frameworks can serve as a powerful counterbalance to the influence of harmful industries.

Our Guests:

• Dominique Mollet - Lecturer in the Faculty of Law at the University of Groningen in the Netherlands.
• Sara Laura Ferrari - Research Fellow in the Department of Biomedical and Clinical Sciences at the University of Milan in Italy.

Oral Health Matters is produced by the Dental Public Health Group at UCL with funding from the National Institute for Health and Care Research (NIHR).

In the second episode of Series 2 of Oral Health Matters, host Richard Watt, Professor of Dental Public Health at University College London, is joined by two global health experts to deconstruct the high-stakes political diplomacy behind the United Nations High-Level Meeting on Non-Communicable Diseases (NCDs).

As global health priorities are increasingly dictated by geopolitical manoeuvring rather than scientific consensus, how do we ensure oral health isn't left behind? This episode provides an insider’s look at the "battlegrounds" of UN declarations - where even the placement of a comma is negotiated - and explores the fallout of the US and Argentina’s decision to block the initial declaration in September 2025. From the influence of commercial interests and "hidden" WhatsApp diplomacy to the rising leadership of lower- and middle-income countries, our guests discuss whether this new declaration is a definitive win or simply a tool for future accountability.

Our Guests:

• Dr. Taskeen Khan – Director of Research at the World Innovation Summit for Health (WISH) and former global health expert at the WHO.
• Dr. Habib Benzian – Professor at the University of Sydney and the University of the Western Cape, and a leading figure in the Lancet Commission on Oral Health.

In the opening episode of Series 2 of Oral Health Matters, host Richard Watt, Professor of Dental Public Health at University College London is joined by two global leaders in dental public health to navigate the complex and often volatile intersection of politics and healthcare.

As geopolitical landscapes shift toward populist agendas, what happens to the world's most vulnerable populations? This episode provides a critical look at how recent political changes in the US and the Global South are directly impacting oral health funding, research, and equity. From the removal of DEI programming in American universities to the withdrawal of major international health funding in South Africa, our guests explore whether this era of "chaos and uncertainty" can be a catalyst for new, innovative models of global collaboration.

Our Guests:
Dr. Bob Weyant - Professor of Dental Public Health at the University of Pittsburgh, USA, and a seasoned policy advocate.

Dr. Khabiso Ramphoma - Associate Professor at the University of the Western Cape, South Africa, and a rising leader in global oral health research.
