Salivary gland stones may cause:

  • dull pain in your mouth that comes and goes
  • swelling in your mouth that flares up from time to time
  • an infection around the stone – signs of infection include pain, redness and a high temperature

If you feel intense pain during mealtimes, this could mean the stone is completely blocking a saliva gland. The pain usually lasts 1 to 2 hours.

Things you can do to try to remove salivary gland stones

You can try to remove a salivary gland stone by doing things to increase the amount of saliva in your mouth, such as:

  • sucking on a lemon or lemon drops
  • drinking plenty of water
  • gently massaging around the stone

If you have pain and swelling, you can:

The symptoms will not go away until the stone has been removed.

Important

Do not use anything sharp to try to remove a salivary gland stone because it could cause injury and infection.

Non-urgent advice: See a GP if:

  • you're unable to remove a salivary gland stone yourself
  • the stone has caused an infection – signs include pain, redness or pus around the stone, and having a high temperature (you feel hot and shivery)

Treatments for salivary gland stones

Small salivary gland stones sometimes fall out on their own.

You’ll continue to have symptoms until the stone falls out or is removed.

A GP may attempt to gently remove the stone with a thin, blunt instrument.

If that's not possible, you may need to have the stone removed in hospital.

Causes of salivary gland stones

It's not clear what causes salivary gland stones, so there's no way to prevent them. They're not usually linked to other health problems.

Once removed, salivary gland stones do not usually come back. But if you keep getting them you might need to have 1 of your salivary glands removed.
