Bad breath is considered to originate primarily from bacteria on the tongue. This study of 29 individuals, 10 of which were free from bad breath, was conducted to find a connection between bad breath and tongue periodontal pathogens. The results of the study suggest that there are five periodontal pathogens on the surface of the tongue that contribute greatly to volatile sulfur compounds (VSC) production. Volatile sulfur compounds are known to cause bad breath.
