Early forms of the toothbrush have been in existence since 3000 BC known as a chew stick.
The bristle toothbrush was invented in 1498 in China. The bristles hairs were taken from a hog’s neck and attached to handles made of bamboo.
In 1938 nylon bristles were introduced by Dupont de Nemours called Doctor West’s Miracle Toothbrush.
Americans became increasingly concerned with the practice of good oral hygiene and quickly adopted the nylon toothbrush.
The first American to patent the toothbrush was H. N. Wadsworth, (patent number 18,653,) in 1857.
Mass production of toothbrushes started in 1885.
The first electric toothbrushes hit the market in 1960.
