Before nylon plastics transformed personal care, cleaning your teeth meant rubbing your gums with soot-covered rags or using toxic powders that did more damage than good. Discover how a jailed London rioter, a livestock bone from a prison dinner, and smuggled Siberian pig bristles created the world’s first mass-produced toothbrush—and sparked a global hygiene revolution.

We treat the toothbrush as an ordinary, inexpensive piece of plastic sitting in a bathroom cup, but it is the single tool that conquered systemic oral infection, saved human smiles, and ended centuries of excruciating dental agony. In the sixth episode of Everyday Things Untold Stories, host Jonathan takes you inside the damp, crowded cells of 18th-century London’s Newgate Prison to uncover the surprising origins of daily dental care.

What You’ll Discover in Episode 6:

• The Prison Cell Breakthrough: How William Addis carved small holes into a discarded animal bone during his 1780 imprisonment, tied stolen bristles through the gaps, and created the prototype for modern toothbrushes.
• Pig Hair & Siberian Boars: Why early toothbrushes relied on stiff boar bristles imported from cold climates like Siberia and China—and why they remained a rare luxury for over a century.
• The Nylon War: How DuPont’s 1938 invention of synthetic nylon bristles eliminated animal hair, dramatically dropped production costs, and made daily oral care accessible to everyone.
• WWII & Mandated Brushing: How military hygiene mandates during World War II forced millions of soldiers to brush daily, cementing the routine in homes worldwide after the troops returned.
