Toothbrushes

The earliest description of a toothbrush was made in a Chinese historical work, dated to approximately 1600 BC. It described a chewing stick, consisting of a twig and a frayed end. Various forms of toothbrush have been used. Indian medicine (Ayurveda) used the twigs of the neem or banyan tree to make toothbrushes and other oral-hygiene-related products for millennia. The end of a neem twig is chewed until it is soft and splayed, and it is then used to brush the teeth. In the Muslim world, the usage of miswak—a type of chewing stick consisting of the roots or twigs of the Arak tree (Salvadora persica), which have antiseptic properties—is common practice and dates to pre-Islamic times.. Muhammad popularized the use of miswak and some erroneously believe it to have been his invention. Rubbing baking soda or chalk against the teeth has also been common practice in history.
