Tongue plays a crucial role in overall oral health. However, many people overlook the importance of cleaning it regularly. Dr Vartika Kumari, a specialist in Dental Medicine at Aster RV Hospital, explains what happens if you skip this simple step for just a month. “A month without tongue cleaning will likely result in a few minor changes in the short term,” she says. “The main change people see is bad breath.” This happens because an unclean tongue collects food particles and bacteria, creating a biofilm that causes unpleasant odour. Research shows that 70-80% of bad breath originates from this tongue biofilm.
Dr Kumari describes the physical changes you might notice: “The tongue might appear whitish or yellowish in colour as a result of buildup over time, especially on the posterior third of the tongue.” This coating can even make your mouth feel sticky despite brushing. Some people may experience a dulled sense of taste because “when the taste buds get covered with residue, flavours can feel a bit dull or not as sharp.” Moreover, the bacteria growing on the tongue can increase plaque formation, leading to cavities and gum disease.
Risks of neglecting tongue cleaning
Neglecting tongue hygiene can lead to bacterial overgrowth and increase the risk of mouth infections. Dr Kumari points out, “The tongue has numerous papillae where food, dead cells, and microbes can easily hide. If this buildup is not removed, it forms the perfect condition for bacteria to multiply rapidly.” These bacteria don’t just stay on the tongue—they can spread to gums and teeth, causing irritation, gingivitis, cavities, and even fungal infections like oral thrush in immunocompromised people.
Poor tongue hygiene can also disturb saliva balance, leading to dryness and discomfort. She warns, “Skipping tongue cleaning may seem harmless, but it gradually creates conditions that allow bacteria to multiply and increase the risk of infections.”

How to clean your tongue properly
Cleaning your tongue daily is essential, and the best tool for this is a tongue scraper. Dr Kumari explains the correct technique: “Stick your tongue out comfortably and place the scraper at the very back of the tongue. With very light pressure, slowly drag it forward. Do not scrape too strongly, as it can irritate the tongue.” After each swipe, rinse the scraper and repeat a few times until the tongue looks clean. If using a toothbrush, gently brush from back to front and rinse thoroughly.
“It is advised to clean your tongue at least once a day, ideally twice,” Dr Kumari adds. This practice helps control bacterial accumulation, remove unpleasant odours, prevent tongue coating, and maintain freshness and good oral health. Thus, taking a few seconds each day to clean your tongue can help prevent bad breath, enhance taste, and protect your teeth and gums from harmful bacteria. Don’t overlook this easy but vital step for a healthier mouth and happier smile.
