<p>Welcome to What’s Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken get to the root of what shapes our health and wellbeing. </p><p>In this episode, they ask why our teeth so often cause pain and problems. They look at how teeth work, why they’re so prone to decay, and what actually causes toothache. They ask when it’s time to see a dentist, what helps with the pain, and whether there’s anything we can do ourselves to prevent it. </p><p>To help answer these questions, they’re joined once again by Praveen Sharma, Associate Professor and Honorary Consultant at the University of Birmingham.</p><p>If you want to get in touch, you can email us at [email protected] or WhatsApp us on 08000 665 123.</p><p>Presenters: Drs Chris and Xand van Tulleken Guest: Dr Praveen Sharma Producer: Maia Miller-Lewis Executive Producer: Rami Tzabar Editor: Jo Rowntree Researcher: Grace Revill Tech Lead: Reuben Huxtable Visual Producer: Leon Gower Digital Lead: Richard Berry Composer: Phoebe McFarlane Sound Design: Ruth Rainey</p><p>At the BBC: Assistant Commissioner: Greg Smith Commissioning Editor: Rhian Roberts</p><p>A Loftus Media production for BBC Radio 4</p>
