Is it permissible to brush one's teeth with a toothbrush during the daytime of Ramadan?

Question : The questioner says: Honorable Shaykh, is it permissible to brush one's teeth during the daytime of Ramadan?

Answer : In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, Lord of the worlds, and may Allah send prayers and blessings upon our Prophet Muhammad, his family, his Companions, and those who follow them in excellence until the Day of Judgment. If the brushing is done without toothpaste, there is nothing wrong with it, as this is ordinary miswak usage, unless blood appears from it, in which case he must spit it out and not swallow it. As for brushing with toothpaste, there is nothing wrong with it either if he controls himself, but controlling the toothpaste is difficult because it flows quickly, so I fear it may go down his throat without him realizing it. What I see is that one should not use toothpaste while fasting, and the matter is broad, and praise be to Allah; one waits until the sun sets.
