why does your breath smell so bad in the morning?!

It only takes a few cells of bacteria, left in your mouth after you brush to cause a stench. The cells multiply so rapidly in the moist warmth of your mouth. Your mouth is almost an ideal incubator for bacteria. So, by morning, a few cells have become a few million cells and the result is bad breath. Try flossing, and brushing your tongue. Your tongue is where most of the bacteria hide.

I think that it's fluid from stomach. And with addition of bacteria on tongue. Brushing teeth won't neutralize the smell. A natural meal would fix that smell. Food such as tuna with oil, fat pig meat, tobacco... To neutralize eat fresh plants, non-additive meat and don't eat much grains.

Do you floss if not that is most likely the cause

because you didnt brush your teeth
