is it impermissible to brush teeth while fasting
IslamToday - English. Many people avoid brushing their teeth during the day in Ramadan. This is a mistake, since there is no contradiction between observing the fast and brushing one's teeth. We must understand that the word âsiwÃ¢kâ does not just refer to the tree branches that are used as tooth sticks, but to the act of brushing the teeth itself.
