White Spots and Blisters on the Tongue: Causes and Management

Oral lesions have diverse etiologies. Clinical features guide diagnosis.

Common Causes

1. Aphthous ulcers (canker sores): Round/oval, yellow-white fibrinous center, erythematous halo. Painful. Non-contagious. Triggers: trauma, stress, deficiencies (B12, Fe, folate), sodium lauryl sulfate toothpaste.
2. Herpangina (coxsackievirus A): Vesicles/ulcers on soft palate, tonsils, uvula. Fever, odynophagia. Children. Self-limited (7–10 days).
3. Hand-foot-mouth disease (coxsackie A16, EV71): Oral vesicles + palmar/plantar vesicles. Fever. Children.
4. Oral candidiasis (thrush): White plaques (cottage cheese) on tongue, buccal mucosa; scrape off → erythema. Risk: antibiotics, steroids, diabetes, dentures, immunosuppression.
5. Oral hairy leukoplakia (EBV): White corrugated lateral tongue lesions; cannot scrape off. HIV/AIDS indicator.
6. Lichen planus: White reticulated (Wickham striae) or erosive lesions. Autoimmune.
7. Leukoplakia: White patch not attributable to other causes; biopsy to rule out dysplasia.
8. Traumatic ulcers: Biting, sharp teeth, dentures.

When to See a Clinician

• Lesions >2 weeks without healing.
• Progressive enlargement, induration, fixation.
• Unexplained weight loss, cervical lymphadenopathy.
• Immunocompromised.

Management

• Symptomatic: topical anesthetics (benzocaine), protective pastes, saline rinses.
• Specific: antifungals (candidiasis), antivirals (HSV), steroids (aphthous, lichen planus).
• Eliminate irritants (tobacco, alcohol, SLS toothpaste).
