You’ve used it today. You’ll use it again tonight. But the toothbrush—the most basic tool of modern hygiene—has a history far stranger than you think. From ancient chew sticks buried with Egyptian elites… To a prison invention made from bone and wire… To a global supply chain built on frozen pig hair… To a scientific breakthrough that institutions tried to suppress… This is not a story about brushing your teeth. It’s a story about power, habit, innovation—and the moments that quietly changed human behavior forever. In this episode of Hidden History, we uncover the forgotten origins of one of the most universal objects on Earth - the toothbrush. 🪥 What you’ll learn: ⏱ Chapters: 0:00 – The Object You Used This Morning 1:30 – Ancient Origins and Civilizations: Chew Sticks & Miswak 3:46 – China and the hog bristle brush 4:21 – Medieval Europe's Dirty Secret 5:05 – William Addis: Invented in a Prison Cell 7:04 – The Fluoride Wars & Institutional Resistance 9:05 – The Electric Tooth
