Most bad breath bacteria live on the tongue. Dry mouth can be caused by certain medications, a salivary gland disorder, or by always breathing through the mouth instead of through the nose. The main symptom of halitosis is a bad smell from the mouth that is considered to be beyond a socially acceptable level. The substances that cause their bad odors reach the bloodstream and reach the lungs, where they are exhaled, says dentist Richard Price, DMD, a spokesman for the American Dental Association.
