Today we’re looking at a phenomenon that happens to all of us: losing our baby teeth and getting new ones! So how do our teeth grow in and what makes them fall out? Naturally, a group of wandering teeth helps us explain. We'll also find out why we have two sets of teeth in the first place. A chatty tooth travel agent will introduce us to all the different ways to send our baby teeth off in style and we'll play a game that will test your knowledge of animal teeth. Plus, the Moment of Um answers the question "Why do bees make a buzzing sound?"You can support Brains On at brainson.org/fans — there you can donate, join our free fan club, check out our merch or buy our book!This episode was sponsored by:Indeed (indeed.com/brainson)Bobby Wonder podcast (gokidgo.com or subscribe to Bobby Wonder on Apple, Spotify or wherever you get your podcasts)See omnystudio.com/listener for privacy information.
