Why do we get Morning Breath? What’s different about breathing in our sleep compared to being awake?

Question

This has always puzzled me, what is happening in our mouth when we’re sleeping?

Answer 1

It’s a build up in bacteria in your mouth, particularly on your teeth and gums that causes this. They build up over night because there’s less movement and eating/drinking while your asleep.

But OP, if you have healthy gums you shouldn’t really be getting noticeably bad breath every morning. Bad breath in the morning is a sign of gingivitis, or the early stages of gingivitis. Get your teeth cleaned at a dentist and start flossing. Trust me, I wish I had started taking proper care of my teeth much sooner
