Asalaamu Alaikum,
"Make a regular practice of Miswak for verily it is the purification for the mouth and a means of the pleasure of the Lord." - Muhammad(pbuh)[1]
Studies
A 2003 scientific study comparing the use of
miswak with ordinary toothbrushes concluded that the results clearly were in favor of the users who had been using the
miswak, provided they had been given proper instruction in how to brush using it.
[2] The
World Health Organization (WHO) recommended the use of the
miswak in 1986 and in 2000 an international consensus report on
oral hygiene concluded that further research was needed to document the effect of the
miswak.

Dr. Rami Mohammed Diabi,
[4] who spent more than 17 years researching the effects of
miswak on health, and especially its anti-addiction effects on smokers (curative and preventive sides), has opened a field of science and research with his last publication: "Miswak Medicine Theory" or Sewak Puncture medicine
[5] which led him to what is called
Beyond Sewak: World of Science and Research.
[6] Miswak also is contributing in the fight against desertification,
[7] thereby affecting our environment and global climate.
8. Toothbrush
According to Hassani, the Prophet Mohammed popularized the use of the first toothbrush in around 600. Using a twig from the Meswak tree, he cleaned his teeth and freshened his breath. Substances similar to Meswak are used in modern toothpaste.
