Whenever i wake up, even from a short evening nap, my breath smells bad..what causes this?
A doctor has provided 1 answer
Decreased saliva: You have reduced salivary production and flow when you sleep and saliva has some anti bacterial agents. So while you sleep, bacteria are growing and producing the bad odor.
