Did you know that toothbrushes were made with boar’s bristles until the first nylon bristles were introduced as a toothbrush innovation in 1938? It’s true, according to the Library of Congress. Here are some other interesting facts about the history of toothbrushes by that learned organization:
- Toothbrushes have been in use since approximately 3000 BC.
- Some of the earliest toothbrushes were “chew sticks” (a twig with a frayed end).
- The bristle toothbrush was invented in China in 1498 and the bristles were taken from the back of a hog’s neck.
- The first mass-produced toothbrush was made by William Addis of Clerkenwald, England, around 1780.
- The first American to patent a toothbrush was H. N. Wadsworth, (patent number 18,653, – yes, the second comma is there) on Nov. 7, 1857.
- Mass production of toothbrushes began in America around 1885.
- One of the first electric toothbrushes to hit the American market was in 1960. It was marketed by the Squibb company under the name Broxodent.
