Inside my mouth burns

A burning mouth can come from irritation, dry mouth, infection, nutritional problems, medication effects, or nerve-related pain.

The symptom may affect the tongue, lips, palate, or lining of the cheeks, with or without visible changes. A careful history helps separate a contact burn from oral thrush, ulcers, reflux, allergy, or burning mouth syndrome.

Stop a suspected irritating product, choose cool soft foods, drink water, and avoid tobacco, alcohol, and very spicy or acidic foods while arranging an assessment. Do not scrape lesions or use leftover antibiotics or antifungals.

See a dentist or doctor if the burning persists, recurs, limits eating, or comes with ulcers, white patches, bleeding, swelling, fever, or weight loss. Sudden facial swelling or breathing difficulty is an emergency.

Ask what the mucosa looks like, whether dry mouth or medicines contribute, and whether testing for infection, blood abnormalities, or nutritional deficiency is needed.
