It is reputed to have been used over 7,000 years ago.[1] The miswak's properties have been described thus: "Apart from their antibacterial activity which may help control the formation and activity of dental plaque, they can be used effectively as a natural toothbrush for teeth cleaning. Such sticks are effective, inexpensive, common, available, and contain many medical properties".[2] It also features prominently in Islamic hygienical jurisprudence.
I don't bother using any toothpaste usually, I nearly always use just water and a hard smokers brush (both have been against recommendations of conventional dentists , telling me that the hard brush will ruin my gums, yet I have been using one for about thirty years or more* and the dentists compliment me on my gum and teeth health each time I visit, the hard brush strengthens the gums after a few brushes)
*not the same one!
