Why Clean Your Tongue Clinical studies have confirmed that odor-causing bacteria on the tongue is the primary cause of bad breath and a potential contributor to other oral health problems such as periodontal disease. Especially during sleep, the tongue accumulates a plaque film of bacteria and other odor causing compounds. The texture of the tongue is very conducive to housing this unwanted material. This is why fresh breath is difficult to maintain, even after brushing your teeth. Brushing your tongue with a toothbrush only stirs up this plaque film, it doesn't effectively remove it.
