Web Page on Halitosis-Fauqueir

Halitosis (also known as bad breath) most often is caused by volatile sulfur compound producing bacteria in the oral cavity (85%). Such bacteria exist on the gums, teeth, tonsils, adenoids, and tongue. Other (less common) causes of bad breath also include reflux, sinus infections, pneumonia, bronchitis, kidney failure, metabolic dysfunction, cancer, etc. The most recalcitrant cause of halitosis (in people with excellent oral hygiene) is due to bacterial overgrowth in the back part of the tongue (lingual tonsils). Adenoids is another location often neglected as a cause of halitosis.
