Question

why Bad breath comes out of your mouth on waking up at Dawn?​

Answer 1

Answer:

Bad breath comes out of your mouth because of poor oral hygiene..

Answer 2

Answer:

If you're not brushing or flossing effectively, food particles can get stuck in crevices on the surface on the tongue, between the teeth, or along our gum tissue. The bacteria in your mouth will break down those food particles, which releases the lovely bad breath come morning time.
