Salivary gland stones

Salivary gland stones are small stones that form in salivary glands in your mouth and can block the flow of saliva (spit). They're not usually serious and sometimes go away on their own.

MARAZZI/SCIENCE PHOTO LIBRARY https://www.sciencephoto.com/media/81080/view 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 if you have salivary gland stones

You can try to ease a salivary gland stone by doing things to increase the amount of saliva in your mouth, such as: drinking plenty of water gently massaging around the stone chewing sugar-free gum or sucking on sugar-free sweets or lozenges If you have pain and swelling, you can: take paracetamol or ibuprofen suck ice cubes or ice lollies The symptoms will not go away until the stone has gone. Important Do not use anything sharp to try to remove a salivary gland stone because it could cause injury and infection.

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.
