The toothbrush as we know it today was not invented until 1938.
However, early forms of the toothbrush have been in existence since 3000 BC. Ancient civilizations used a "chew stick," which was a thin twig with a frayed end. These 'chew sticks' were rubbed against the teeth.
Other information:
* 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,) 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.
