Is it Harmful to swallow the morning (just wakeup) saliva?
After wake up(still in bed) or when i am about to wake up i unintentionally swallow the saliva collected in my mouth. This happens once or twice a month. Mostly saliva secrets 2 - 3 mins after wakeup... Sometimes it secrets immediately after getting conscious. The taste is bitter and the odor is bad... How harmful is the saliva that i have swallowed?
