A mouth ulcer that won't heal?

A small mouth ulcer can make brushing and eating uncomfortable. Most settle within one or two weeks, but a persistent sore deserves a closer look.

Keep care gentle

Use a soft toothbrush and avoid things that sting or scrape the sore. Very hot drinks, spicy or acidic foods and rough textures can make it more uncomfortable. Ask a pharmacist about suitable pain relief or mouth treatments.

Notice possible irritation

A sharp tooth, braces or poorly fitting dentures may be rubbing the area. Mention these to your dentist rather than repeatedly covering up the discomfort.

Do not ignore a lasting sore

See a dentist or clinician if an ulcer lasts more than three weeks, looks different from previous ulcers, bleeds or becomes increasingly painful. A persistent ulcer is not always serious, but it needs assessment.
