mouth

Salam, i wanted to know, after I eat bread, there are still some crumbs left in my mouth. If I rinse three times, there are still small crumbs left. (small). Do I have to brush my teeth to get it all out? If I don't then I am afraid that I will eat during my prayer

Dear scholars, As-Salamu `alaykum. Is it permissible for a man to give the “kiss of life” (mouth-to-mouth resuscitation) to a female drowning victim? Jazakum Allah khayran.
