Bad breath or so called “halitosis” is the result of certain foods and lack of oral hygiene. Food particles that remain in the mouth and in between the teeth after meals, if not cleaned by brushing, cause bad breath.
Home Remedies for Bad Breath
The stale food particles decay in the mouth and cause bacteria, thus releasing sulfur compounds causing the awful smell. Raw onions and garlic in the food too cause bad breath. Other causes for halitosis could be tooth decay, infection of the throat, smoking, stomach disorders, alcohol, diabetes or even stress.

Some simple and easy home remedies, however, could help one get rid of the bad breath. It is important to brush the teeth after each meal to discourage bacteria from growing in the mouth, thus preventing bad breath.
