None of the activities you list will kill all the bacteria in your mouth and upper respiratory system.
While you sleep you don’t do much activity wise. Your mouth is a warm, moist place with a constant supply of oxygen blowing across it. Its a perfect environment for stuff to grow…. so it does.
So no matter how well you brush, floss, or use mouth wash, stuff is going to grow in your mouth. And it tends to smell after a couple of hours.
To quote Jurassic Park: Life….uh…. finds a way
The actual answer is that when you’re asleep, you’re not drinking water.
Saliva contains antibacterial agents that help combat bacterial growth in the mouth throughout the day. However, saliva is water based, & as such you will produce less when you’re drinking less water, allowing for bacteria to grow with less resistance.
You will also notice bad breath when you have a dry mouth or are dehydrated.
There are billions of bacteria and other microbes in your mouth, even after you brush, floss and mouthwash. While you’re awake, you brush, eat food and do other stuff that’ll basically cause you to swallow bunches of them.
But at night they’re free to just eat and reproduce unimpeded. And bacteria reproduce every few hours. If those 20 billion just reproduce twice during a night that goes from 20 to 40 and from 40 to 80 billion in the space of one night. And that’s just the bacteria.
Not only are they reproducing, they’re also eating and anything that eats… well, let’s just say that your breath smells by morning because you got a 80 billion bacteria and they all shit in your mouth.
