Good oral hygiene helps keep your tongue healthy. Scrape your tongue gently while brushing your teeth, along with plenty of hydration, no smoking, and a well-balanced diet containing vitamins and minerals.
Your tongue serves as an easy yet effective tool to reveal your current state of health. Early detection of health issues including nutritional deficiencies, infections and chronic diseases becomes possible through monitoring your tongue’s color, changes, coating texture and shape and size.
