Consistent with previous studies, we found no single bacterial species whose presence explains oral malodor. However, our results revealed that a large amount of H2S or CH3SH in the oral cavity is produced by characteristic oral microbiota structures, suggesting that suppression or elimination of specific bacterial populations may effectively reduce oral malodor. Although a methodology of altering the stable oral microbiota remains unknown, this may represent a treatment option in addition to the conventional steadfast mouth-cleaning routine that focuses on reducing the total bacterial load in the oral cavity.

well duh we knew this, now let's get it started!!!
