Possible Cause: Oral Thrush (Candidiasis)

A white or yellowish coating on the tongue can be a sign of oral thrush, a fungal infection caused by an overgrowth of Candida albicans. This yeast naturally exists in the mouth, but certain conditions can lead to an imbalance and subsequent infection.
Common Causes:

Poor oral hygiene
Antibiotic use, which disrupts healthy bacteria
A weakened immune system (e.g., in people with diabetes or HIV/AIDS)
Smoking or dry mouth
Symptoms:

Thick white or yellow patches on the tongue or inner cheeks
Slight burning or soreness
A metallic or unpleasant taste
Bad breath
Prevention and Home Care:

Brush your teeth and clean your tongue twice daily
Rinse your mouth with saltwater or baking soda solution
Avoid sugary and yeast-rich foods that can feed the fungus
Incorporate probiotic-rich foods like yogurt and kefir
Stay well-hydrated and maintain good dental hygiene
When to See a Doctor:

If the white patches persist for more than a week, or if you experience pain, see your dentist or healthcare provider. Antifungal treatments may be required for moderate to severe cases.
