What can cause lips to feel raw or burning?

Burning or raw lips can result from irritation, dryness, allergy, infection, medicines or an oral condition.

Why can lip products and saliva irritate the lips?

The lips contain a thin skin barrier and a moist mucosal surface that can react to saliva, toothpaste, lip products, foods, dental materials or repeated licking. Burning may also accompany angular cheilitis, oral thrush, nutritional problems, nerve sensitivity or systemic illness.

What can you do to soothe raw or burning lips?

Stop newly introduced fragranced or flavoured lip products, avoid licking or biting the lips, use a bland protective emollient, and note foods, medicines and dental products linked with flares. A clinician may inspect the lips and mouth and review medications or take a swab when indicated.

When does burning or rawness of the lips need dental care?

Seek care for spreading swelling, blisters, ulcers that do not heal, bleeding, fever, difficulty swallowing, or a persistent patch. Sudden lip swelling with breathing difficulty is an emergency.

What should you ask about persistent burning lips?

Ask whether the surface shows dermatitis, infection, ulceration or nerve-related burning, whether a product should be stopped, and whether a swab, blood test or medication review is appropriate.
