The first toothbrush is believed to be invented in China in 1223. A Japanese master said that he had seen some monks cleaning their teeth with a brush when he was in China. The brush was made of horse hair tied on the end of a stick made of ox bone. How ever in 3000 BC, Ancient civilizations used a thin twig with a frayed end called a "chew stick." These twigs cleaned teeth with a rubbing action. Now manual tooth brushes are made up of plastic and synthetic fibers that are made of nylon.The first electric toothbrush was invented in Switzerland, 1954. Electric toothbrushes were originally created for patients with limited motor skills, as well as orthodontic patients.
