Oral Thrush: Symptoms, Causes, and Effective Treatments

What is oral thrush?

Oral thrush, also called oral candidiasis, is an infection caused by a fungus naturally present in the mouth: Candida albicans. When the balance is disturbed, this fungus can overgrow, causing uncomfortable lesions inside the mouth.

Symptoms of oral thrush

The most common signs are:

• White or creamy patches on the tongue, palate, or inside the cheeks

• Burning or irritation sensation in the mouth

• Sore or cracked tongue

• Bad or metallic taste

• Sometimes difficulty swallowing or speaking

💡 Oral thrush is not contagious but requires medical treatment.

What causes oral thrush?

Oral candidiasis can be triggered by:

• Poorly maintained dental prosthesis

• Prolonged antibiotic or corticosteroid treatments

• Poor oral hygiene

• Dry mouth (lack of saliva)

• Poorly controlled diabetes

• Tobacco, alcohol, stress

• Weakened immune system (HIV, chemotherapy, etc.)

Who is most at risk?

• Elderly people, especially those wearing removable dentures

• Infants

• Immunocompromised patients

• Smokers

How is oral thrush treated?

Treatment includes:

• Local antifungal agents (gel, mouthwash, lozenges)

• Sometimes oral antifungal treatment in case of recurrence

• Better maintenance of dental prostheses

• Improved oral hygiene

⚠️ Never self-medicate. Diagnosis by a dentist or doctor is essential.

Preventing recurrences

✅ Brush teeth twice daily and clean the tongue
✅ Maintain dentures properly
✅ Limit sugar, tobacco, and alcohol
✅ Avoid prolonged use of harsh mouthwashes
