Sore or white tongue

A sore or white tongue is not usually serious and is often easily treated.

Do

  • use a soft toothbrush to brush your teeth

  • brush your tongue or use a scraper to help improve a white tongue

  • use a straw to drink cool drinks

  • take paracetamol or ibuprofen

Don't

  • do not use a toothpaste that contains sodium lauryl sulphate

  • do not eat hard, spicy, salty, acidic or hot food and drink that may irritate your tongue

  • do not smoke

  • do not drink alcohol

  • what's causing your sore or white tongue
  • if you can buy anything to help with any pain or irritation
  • if you should see a dentist or GP

Biting or burning your tongue with hot food or drink can cause pain and swelling. But this should only last a few days.

A white tongue can be a sign of a health condition.

Do not self-diagnose – see a GP if you're worried.
