For some people who suffer from halitosis (severe bad breath), it can be really embarrassing. It's often caused by the breakdown of bacteria in a person's mouth, which produces a foul-smelling sulfur odor on the tongue. Bad breath can also originate in the lungs or sinuses.
Now researchers at the State University of New York at Buffalo School of Dental Medicine have identified a specific tongue bacteria that causes chronic bad breath. I don't mean to gross you out, but they say that the bacteria known as Solobacterium moorei, can also be found in human feces. Um, eww.
In the small study, scientists collected samples by scraping an area of the tongue's surface in 21 people with bad breath and 36 without. This bacteria was found in every person who had halitosis. So now that researchers have discovered this bacteria, now they can help come up with treatments to rid people's mouths of it.
