Why does your breath smell worse in the morning?

Good morning! Rise and shine! Time to stretch and yawn and…blech! What is that taste? What is that smell?? Morning breath can be especially stinky, even if you brush your teeth the night before. What’s up with that? We asked Dr. Michael Eggert, who teaches in the dental school at the University of Alberta to help us find the answer.
