Toothache

NHS information about the causes of toothache, when to see a dentist, and how toothache can be relieved and prevented.

About this information

This NHS content is written for people in England. Services, contact routes and treatment arrangements may differ in other countries.

See a dentist if you have toothache:

  • that lasts more than 2 days
  • that does not go away when you take painkillers
  • with a high temperature, pain when you bite, red gums, or a bad taste in your mouth
  • and your cheek or jaw is swollen

Do not go to your GP as they will not be able to give you dental treatment.

Go to A&E if you have toothache and:

  • the area around your eye or your neck is swollen
  • swelling in your mouth or neck is making it difficult for you to breathe, swallow or speak

A&E safety messaging

Do not drive to A&E. Ask someone to drive you or call 999 and ask for an ambulance.

Bring any medicines you take with you.

How to ease toothache while waiting for an appointment

Do

  • take painkillers, like ibuprofen or paracetamol (children under 16 should not take aspirin) – a pharmacist can advise you

  • use a pain-relieving gel for your mouth – this can be bought from pharmacies or supermarkets

  • try rinsing your mouth with salt water (children should not try this)

  • eat soft foods, like yoghurt or scrambled eggs, and try to avoid chewing with the sore tooth

  • use a soft toothbrush and avoid flossing around the sore tooth

Don't

  • do not eat foods that are sweet, very hot or very cold

  • do not smoke – it can make some dental problems worse

How to rinse with salt water

  1. Dissolve half a teaspoon of salt in a glass of warm water – warm water helps salt dissolve.
  2. Rinse your mouth with the solution, then spit it out – do not swallow it.
  3. Repeat as often as you like

Children should not try rinsing their mouth with salt water in case they swallow it.

Tooth pain can also be caused by having sensitive teeth.

How to prevent toothache

The best way to prevent toothache is to keep your teeth and gums as healthy as possible.

To do this:

  • have regular dental check-ups
  • cut down on sugary foods and drinks – only have them as an occasional treat at mealtimes
  • brush your teeth twice a day for about 2 minutes with a fluoride toothpaste
  • clean between your teeth using floss or an interdental brush every day to remove food, debris and plaque
