Most people overlook their tongue, but it’s actually a powerful reflection of what’s going on inside your body. If you’ve noticed unusual coatings, colors, or textures, it’s time to pay attention. Here are four common tongue appearances and what they might be trying to tell you.
1. White-coated tongue
A thick white coating may suggest poor oral hygiene, fungal infections like oral thrush, or even a weakened immune system. It can also be linked to dehydration or excessive consumption of dairy or sugar.
What to do:
- Brush your tongue gently every morning using a tongue scraper or soft toothbrush
- Rinse your mouth with salt water or diluted hydrogen peroxide
- Stay well hydrated throughout the day
- Limit sugar and dairy intake
- Consult a doctor if the coating persists for more than a week
2. Dry, peeling tongue
This appearance can signal vitamin deficiencies, especially B vitamins and iron. It may also indicate a reaction to irritants in toothpaste or mouthwash, or a mild allergy.
What to do:
- Include more leafy greens, whole grains, and legumes in your diet
- Switch to a non-irritating, alcohol-free mouthwash
- Drink enough water and avoid overly spicy or acidic foods
- Consider a multivitamin after consulting a healthcare provider
