There are a number of medical terms for bad breath: halitosis, stomatodysodia, fetor oris, ozostomia. Irrespective of the terms used, it indicates to the presence of a foul smell odor that comes from the mouth cavity.

In most of the cases, the odor originates from the mouth, throat and tonsils. If the condition does not improve even after brushing, flossing and rinsing the mouth, the condition maybe chronic.

The foul odor is usually caused by a group of sulfur-producing anaerobic bacteria that harbor beneath the surface of the tongue, throat or the tonsil area.

As these bacteria feast on the proteins from food, the excrete waste in the form hydrogen sulfide, methyl mercaptan. These chemical compounds are odorous. As long as these anaerobic bacteria feed on proteins and excrete these volatile sulfur by-products, your breath will become and worse and worse.

Persistent bad breath and bad taste could be a warning sign of periodontal disease, which is caused by buildup of plaque on teeth. Not having healthy oral habits leads to formation of toxins in the mouth which can irritate the gums. And if untreated, the condition can damage gums and even jawbone. Poor dental fittings, yeast infection of the mouth and dental caries are also one of the causes of bad breath.
