A sour food or drink can irritate the oral lining, causing burning, redness, tenderness, or peeling that usually needs removal of the irritant and observation.
How can you calm an acid-irritated mouth?
Rinse with water, avoid acidic and spicy foods, choose soft cool foods, and do not scrub or peel the irritated tissue.
When does a mouth burn need dental care?
Seek prompt care for spreading swelling, inability to drink, breathing or swallowing difficulty, or a sore that does not heal.
What should you ask about a suspected mouth burn?
Ask about the diagnosis, alternatives, materials, maintenance, and the complete written plan before treatment.
