The lips, cheeks, tongue, and palate can develop a white, peeling, painful patch after contact with a dental product, medicine, or cleaning chemical.

Remove the substance and rinse with water. Avoid rubbing, picking, smoking, alcohol, and spicy or acidic foods; do not induce vomiting after swallowing a chemical.
