Why does my mouth stink when I wake up, even when I brushed at night? How do I fix this?
simple reason why: When you sleep, your mouth dries out. When your mouth dries out, odor-producing bacteria proliferate. “When you sleep, your normal flow of saliva decreases,”. Maintaining impeccable oral hygiene is both the best quick fix and long-term solution for a bad breath of any kind. Brush your teeth immediately before you go to bed at night, and don't eat or drink anything afterward. Doing so can introduce food particles that will be broken down over night.
