Inside mouth red and burning

Red, burning tissue inside the mouth can result from irritation, infection, inflammation, dryness, an ulcer, or a reaction to a product or medicine.

The cheeks, tongue, palate, gums, and floor of the mouth have different tissues and causes. Hot foods, tobacco, alcohol, sharp teeth, appliances, yeast overgrowth, and dry mouth can produce redness or burning.

Stop any newly introduced mouthwash, lozenge, toothpaste, or food that clearly triggers symptoms. Choose cool soft foods and avoid tobacco, alcohol, and very hot or spicy items while the tissue settles.

Book an examination if symptoms persist, recur, impair eating, or occur with white patches, ulcers, bleeding, swelling, fever, or a neck lump. Seek urgent care for rapidly increasing swelling or difficulty breathing or swallowing.

Describe the sites, onset, triggers, medicines, dryness, recent antibiotics, dentures, and tobacco use. Ask whether a swab, medication review, or appliance examination is needed.
