The invention of the toothbrush has a surprisingly long history. Following excavations all over the world, it's been discovered that various methods from chew sticks, tree twigs, bird feathers, animal bones, and even porcupine quills have been used since almost the dawn of human existence. The earliest probable 'invention" came in 1600BC in China, consisting of a chewing stick made out of a twig with a frayed end. As for toothpaste? Common practice recommended baking soda or chalk for such a task. In Europe, William Addis in England is believed to have produce the first mass-produced toothbrush in 1770. Jailed for causing a riot, in prison he decided the method for cleaning teeth with a rag could be improved. He took a small animal bone, drilled small holes in it, obtained some bristles form aguard, tied them in tufts, passed the tufts through the holes on the bone, and glued them in place: the toothbrush was born! It was only in 1857, however, that American H.N. Wadsworth took out a patent for such a device.
