Welcome to Oral Health Matters, a brand new podcast from the Dental Public Health Group at University College London and presented by eminent dental public health expert Professor Richard Watt. In this first series of our podcast, we'll be in conversation with researchers, policymakers and activists from around the world who are working to better understand the causes and consequences of oral diseases and to identify possible policy solutions to improve oral health. So if you're a policy maker, clinician researcher, or member of a community who wants to know more about why oral health matters and what interventions and policies might make a difference, please follow us wherever you find your podcasts. Oral Health Matters is produced by the Dental Public Health Group at University College London, with support from Research Podcasts and funding from the UK National Institute of Health and Social Care Research.
