You need not go for antiviral treatment unless advised by a dermatologist after checking up the ulcers. Mouth ulcers can have causes that aren't due to underlying disease. Examples include canker sores, burns, biting the tongue or cheeks, or eating acidic foods such as sour sweets and pineapple. The usual treatment for mouth ulcers avoid spicy and sour foods until the ulcers heal. Drink plenty of fluids. Regularly rinse your mouth out with warm, slightly salted water. Keep your mouth clean. Take pain-relieving medication, such as paracetamol. Apply antiseptic gel to the ulcers.
