Miswak

The miswak (miswaak, siwak, sewak, Arabic: سواك‎ or مسواك) is a teeth cleaning twig made from the Salvadora persica tree (known as arāk, أراك, in Arabic). A traditional and natural alternative to the modern toothbrush, it has a long, well-documented history used over 7000 years ago.

In Islam the Miswak is also sunnah as the prophet Muhammad pbuh had said: ‘If I had not found it a hardship for my Ummah, I would order them to make wudu’ for every salat and to use miswak in every wudu’. (Bukhari, Muslim)
