Question: how to get morning breath?

Bacteria! You know how your teeth feel smooth after you have brushed them, but really furry when you don’t? Thats because bacteria grow on your teeth. And during the night because you arent moving your tongue or eating, the bacteria can grow undisturbed. Bacteria arent like us, they can breath oxygen but some can also breathe carbon dioxide – it is these bacteria that make the bad smells that cause morning breath. Yummy!
