Halitosis or most commonly called bad breath are terms used to describe noticeably unpleasant odor of a breath of a person. It is usually caused by an accumulation of bacteria in the mouth as a result of gum disease, food, or plaque.
Most often than not, the person with halitosis does not know he has before others know. Most people are too embarrassed to say anything to the person with bad breath. The majority of people with halitosis who don't know they have it, most of them are told by a very close friend or family member.
