Why does my mouth stink?

This is a common problem faced by many people. This may result in social isolation and depression.Our breath smells of whatever we eat or drink. Even the vitamins or multivitamins we eat are responsible for the foul smell. Due to lack of oral hygiene ,the food particles get entrapped in our mouth and result in tartar or plaque formation. This results in peridontal disease,another reason for bad breath. People eating spicy, non vegetarian food are also known to have smelly mouth. Some foods like onion, garlic are responsible for bad breath(temporarily). Stomach acidic reflux is also known to add to foul mouth smell. Eating processed and packed foods is another reason for bad breath. Dehydration is another common cause. Inspite of not eating the whole night our mouth stinks. The reason is Our saliva accumulates in our mouth while sleeping and bacteria feeds upon it. That is why our mouth stinks in morning.
