Tongue fungal infections, often caused by *Candida* overgrowth, are linked to poor oral hygiene, antibiotics, or weakened immunity. These disrupt the mouth’s natural balance, allowing fungus to thrive.

**Red Glossy Tongue:**
One sign is a red, smooth, glossy tongue with a burning feeling. This worsens with spicy or acidic foods. It may also signal iron-deficiency anemia, which can cause fatigue.

**White or Yellow Coating:**
Another symptom is a thick white or yellow layer on the tongue—commonly called oral thrush. It may cause mild burning, bad breath, or a metallic taste.

**Taste Changes and Discomfort:**
“Food tastes dull, bitter, or even metallic,” the article notes, reducing appetite and potentially leading to poor nutrition in severe cases.

**Home Remedies:**
Gently brush your tongue twice daily and rinse with saltwater or baking soda. These simple steps make the mouth less inviting for fungal growth.

**Prevention:**
Good oral hygiene, hydration, and limiting sugary or yeast-rich foods can help. “Probiotics may help restore healthy oral flora” if antibiotics are used. People with weak immune systems should seek medical advice.
