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

Answer 1

Brush your teeth before bed, but not RIGHT before going to bed. Toothpaste will dry out your mouth and then going right to sleep will have you going 8-ish hours without saliva production. I brush hours before bed to ensure there has been enough saliva production to keep things kosher throughout the night.
