From The Simpsons’ Big Book of British Smiles to Austin Powers’ ochre-tinged grin, American culture can’t stop bad-mouthing English teeth. But why? Are they worse than any other nation’s? June Thomas drills down into the origins of the stereotype, and discovers that the different approaches to dentistry on each side of the Atlantic have a lot to say about our national values. In this episode, you’ll hear from historians Mimi Goodall, Mathew Thomson, and Alyssa Picard, author of Making the American Mouth; and from professor of dental public health Richard Watt. This episode was written by June Thomas and edited and produced by Evan Chung, Decoder Ring’s supervising producer. Our show is also produced by Willa Paskin, Katie Shepherd, and Max Freedman.
