One of the most important benefits of tongue scraping is that it helps remove bacteria from your tongue. Brushing and rinsing alone only remove the outer layer of bacteria, but the cells beneath it still thrive. Removing toxins and bacteria from the tongue may support better digestion and overall gastrointestinal health. A clean tongue allows your taste buds to function better, enhancing your ability to taste flavors in food and beverages. Accumulation of debris on the tongue can dull taste sensations over time.
