Can I brush my teeth or use toothpaste while fasting?

“A1) It is permissible to use the Miswaak whilst fasting, on condition that it is not flavoured. A2) If a food particle (smaller than a chickpea) was stuck in between the teeth and swallowed, it does not invalidate one’s fast, as it is difficult to prevent it from entering the stomach.”

“The mint flavour in a flavoured miswak’s is added to the miswak and is not the natural flavour of a miswak. Tasting anything without a valid Shari`ah reason while fasting is makrooh (disliked) and therefore should be avoided while fasting.”

“Brushing teeth in itself will not nullify the fast as nothing is ingested but tasted. Accordingly, it will be makrooh to use toothpaste and should be avoided. One should use a miswāk instead.”

“Yes, it is permissible to wet the miswaak before using it while fasting.”
