Researchers at The University of Glasgow identified 39 new bacteria that hide on the back of the tongue and cause halitosis. The scientists named the new bacteria on known bacteria with similar attributes, Prevotella melaninogenica and Prevotella pallens. While some mouthwashes kill bacteria, they can only be used for a brief time, so they aren’t effective. Other mouthwashes only mask halitosis. Now that these culprits have been identified, the next hurdle is finding out how to combat them.
