The primary reason for the unpleasant odour is poor oral hygiene. Proper brushing methods like brushing of gums , tongue and the roof of the mouth will eliminate the bacteria in the mouth and prevent the foul odour.
Bad breath can occur in the people who have kidney failure, liver malfunction and regular tobacco users also contribute to the foul odour. The saliva plays a vital role in keeping the odour under control. During sleep the salivary glands slow down production of saliva and this promotes the growth of bacteria. Hence it is always advicable to brush the teeth after sleep.
