Using Toothpick Before Fajr Adhān Is Mustaḥab
Issue No. 1340- If a person wishes to fast, it would be better for him to wash his teeth and use a toothpick before the fajr adhān. And if he knows that some particles of food have remained in between his teeth which will go down into his stomach during the day, the obligatory precaution is that he must clean his teeth and use a toothpick. If he does not wash his teeth and something enters the throat, he should complete the fast of that day and later perform it as qaḍā.
