A miswak, or siwak, is a softened small stick with which the teeth are rubbed and cleaned. The end is shaped into a brush through biting or chewing, which serve to separate the fibers and release the healing herbal powers of the twig. Some advantages of the miswak are that is does not require toothpaste, water or a special area to use it, and may be easily carried in one's purse or pocket. It is also disposable and biodegradable - therefore, it is the ultimate environmentally safe toothbrush. Some people even believe it works better than a toothbrush.

Nevertheless, a more compelling reason to use the miswak is that it is Sunnah to do so.

Abu Hurairah reported that Prophet Mohammad (saws) said, "Were it not that I might overburden believers, I would have ordered them to use the miswak at every prayer" (Imam Muslim, Vol. 1).

Abu Hurairah (May Allah be pleased with him) reported:
The Messenger of Allah (PBUH) said, "Had I not thought it difficult for my Ummah, I would have commanded them to use the Miswak (tooth-stick) before every Salat.''
[Al-Bukhari and Muslim].

We learn from this Hadith that the Prophet (PBUH) liked to clean his teeth with Miswak with every Salat, but he did not made it obligatory for the reason that it would be inconvenient for his followers. It shows that he was extremely affectionate and kind to his Ummah.

According to researchers it is this regular cleaning of the teeth, along with a proper diet, that makes the difference between healthy and unhealthy teeth. Keeping your teeth clean is as important Islamically as it is medically. It is as difficult to envision speaking to Allah (through prayer) with bad breath and dirty teeth as it is to envision speaking to a friend when you are suffering from bad breath and dirty teeth. The Prophet himself (saws), uséd to use the miswak before every prayer (Sahih Muslim, Vol.1). Modern science suggests we would do well to follow his example.
