The ruling on using toothpaste for the fasting person
Machine translationRead the Arabic original
Question:
If a person uses toothpaste with the intention of making his breath smell good, does he lose the reward, may Allah reward you? Because the bad breath is a torment, may Allah reward you?
Answer:
No, no one can reduce it to some extent, and it rises every hour, but something like this may reduce it somewhat. So if he does it, there is nothing wrong with it. He rinses his mouth with soap, with the toothpaste, with these things they make; it does no harm.
