Can we brush or teeth while fasting in manner of caution so as to ensure nothing goes down the throat?
Assalaamu Alaikum Wa Rahmatullah,
الجواب و بالله التوفيق
Yes, you can do so. However, in the case of toothpaste, this has a taste, and ‘tasting’ something without a valid reason is Makrooh while observing the fast. Hence, you should refrain from using toothpaste in order to avoid that which is Makrooh while fasting.
And Allah Knows Best.
