How do people end up with bad morning breath even though we brush, floss and use mouthwash regularly.
In: Biology
There are aways bacteria in your mouth, even after brushing, mouthwash, etc. Their excrement (poop) smells bad. When you’re awake you make plenty of spit and swallow often to keep washing away some bacteria and their poop. When you’re asleep you make very little saliva and don’t swallow, so the bacteria and their poop just piles up for hours. That smells.
