You would still get morning breath

It's the result of your mouth being dry while you sleep which allows more bacteria to grow. Flossing doesn't change that
Look breh, I’m telling you for a fact, I don’t have morning breath. That shyt literally smell like nothing when I wake up. If you get teeth cleanings like twice a years, and practice good oral healthcare, your breath will never stink. Never nikka.
Now if you got something like extra teeth that will make it impossible to get certain places with floss, it’s nothing you can do (except have the teeth removed) I’m not even sure what would cause dry mouth. My shyt always seen pretty lubricated (no homo) but even then, if you floss and brush before you got to bed and remove the food particles, it wouldn’t matter how dry your mouth gets. I don’t know though. I do know I don’t have morning breath though.
