## Tongue Fungal Infection: Symptoms, Causes and Safe Care
Oral thrush is a fungal infection caused by an overgrowth of *Candida*. It can cause white patches, a sore or red tongue, unpleasant taste, burning, and difficulty eating or drinking.
### Common Causes
Risk can increase after prolonged antibiotic use, with dry mouth, poor oral hygiene, asthma inhalers, dentures, diabetes, or a weakened immune system.
### What Can Help?
Maintain good oral hygiene, gently clean your tongue, stay hydrated, and rinse your mouth after using inhalers. Avoid smoking and keep dentures clean.
### When to See a Doctor
A white or sore tongue can have several causes, so avoid self-diagnosing. Seek medical advice if symptoms persist, worsen, or cause pain or difficulty swallowing. Oral thrush may require antifungal treatment.
