Mouth acid burn
A chemical mouth burn needs residue removed and water rinsing; severe injury or swallowed chemicals need urgent advice.
The short answer
A chemical or acid burn in the mouth can injure the lining of the lips, cheeks, tongue, or palate; remove the substance, rinse with water, and seek urgent advice for severe or swallowed exposure.
How can chemicals damage the lining inside your mouth?
The oral lining is thin, moist mucosa that can be damaged by acids, alkalis, solvents, concentrated medicines, or heated chemicals. Injury may cause burning, redness, peeling, ulcers, swelling, or a white surface where tissue proteins have been altered.
How should you rinse your mouth after chemical exposure?
Spit out the substance, remove contaminated material, and rinse the mouth repeatedly with clean water without swallowing it. Do not induce vomiting, neutralize the chemical with another substance, or scrub the tissue; keep the container or label for poison advice.
When does a mouth burn need urgent dental or medical care?
Get urgent medical or dental assessment for a strong chemical, a large or deep burn, ongoing pain, swelling, vomiting, swallowing difficulty, breathing symptoms, eye or skin exposure, or any swallowed product.
What should you tell the dentist after a chemical mouth burn?
Ask what substance and concentration were involved, whether the airway or swallowing tube could be affected, what foods and rinses are suitable during healing, and whether an ulcer needs review.
