Halitosis refers to bad breath which is not only a sign of ill health but a social a social stigma. Unfortunately, most people who have halitosis are not even aware of their problem and the discomfort they cause to others.

The most common cause of halitosis is bad teeth and gum conditions. Dental decay at the roots of the teeth may result in abscesses in the gums with foul-smelling, pus giving an objectionable odor to the breath. Even small holes in the teeth may provide a place where germs can multiply and release foul orders.

Other causes of halitosis are any conditions of the nerves, throat, respiratory tract, or stomach which are associated with chronic infection or local upsets of one sort or another, such as chronic tonsillitis, lung diseases like chronic bronchitis and bronchiectasis, chronic gastritis and sinuses which cause a discharge at the back of the throat. Most cases of bad breath are caused by gastrointestinal disorders, intestinal sluggishness and particularly by chronic constipation. The unpleasant odor results from an exceptionally large amount of waste matter being expelled through the lungs. Chewing pan and tobacco and smoking are other causes of bad breath.
