Question

why do we get bad smell from our mouth after we wake up in the morning ?​

Answer 1

Answer:

Odor-causing bacteria accumulate between your teeth and on your tongue, so practicing good dental hygiene will do a lot to improve your morning breath. When you brush, be sure to do so for at least two minutes, not the 35 or 40 seconds that many people do. After you brush, go directly to bed!

Answer 2

Answer:

when we do not clean our mouth before sleeping some of the food remains in our mouth and our saliva contains lysozymes which decomposes those food particles and causes odur.
