Chemicals in Our Teeth

Dr. Christine Austin uses teeth to study childhood development, exposure to chemicals, and stress. She teaches comedians Todd Barry, Michelle Buteau, and Negin Farsad about the secret rings hidden in our molars, why you don't want to inhale tooth dust, and how tooth analysis might hold the answers to some of our most frustratingly persistent diseases. Hosted by Chris Duffy. Produced by Pretty Good Friends.
