Regular salivary flow stops with sleep. This allows mouth germs an opportunity to feed on remaining food particles, old shed mouth lining cells, and stagnant saliva. The byproducts of bacterial metabolism produce the foul odor.
Though the causes of breath odour are not entirely understood, most unpleasant odors are known to arise from food debris trapped in the mouth which is processed by normal mouth flora; there are over 400 types of bacteria found in the average mouth. Several dozen of these can cause trouble when allowed to flourish or are genetically disposed to overpopulate. Large quantities of these naturally-occurring bacteria are often found on the posterior of the tongue, where they are undisturbed by normal activity. The rough surface of the tongue dorsum provides an ideal habitat for anaerobic bacteria, which flourish under a continually-forming tongue coating of food debris, dead cells, and hundreds of thousands of bacteria, living and dead. When left on the tongue, the anaerobic respiration of such bacteria can yield either the putrescent smell of polyamines, or the “rotten egg” smell of volatile sulfur compounds (VSCs) such as hydrogen sulfide, methyl mercaptan and dimethyl sulfide, depending on the bacteria type. It is generally these compounds which, when mixed with mouth air and exhaled, produce unpleasant breath.
I think it’s because your mouth dries out, especially if you breathe through your mouth during sleep. This allows bacteria to grow and provides that great morning breath aroma….I think.
all the food that sitcks on to your mouth n teeth surface has ample time to be attacked by bacteria wen you are asleep. so thus you get the bad breath. thats the reason most people brush their teeth before goin to bed.

Bacteria has time to grow during your sleeping hours.

Ask your mouth.

August 27th, 2007 at 1:43 pm
Because i said so

That is becaus ethe enzymems in our mouth acts on the food substance in our mouth, when we sleep

Its the bacteria in your mouth releasing waste.
