A variety of oral hygiene measures have been used since before recorded history. This has been verified by various excavations done all over the world, in which chewsticks, tree twigs, bird feathers, animal bones and porcupine quills were recovered. Many people used different forms of toothbrushes. Indian medicine (Ayurveda) has used the neem tree (a.k.a. daatun) and its products to create toothbrushes and similar products for millennia. A person chews one end of the neem twig until it somewhat resembles the bristles of a toothbrush, and then uses it to brush the teeth. In the Muslim world, the miswak, or siwak, made from a twig or root with antiseptic properties has been widely used since the Islamic Golden Age. --
