Using Toothpaste When Fasting
Posted: 13 ramadan 1435, 11 July 2014
Q.): Is it permissible to use toothpaste or mouthwash when fasting?
If this was mistakenly swallowed then the fast will break and qaza is necessary. Therefore we advise that this should rather be used before Sehri and after Iftar, not whilst fasting.
And Allah Ta'ala Knows Best
