Salivary gland stones

Also called Sialolithiasis or Salivary stones

Salivary gland stones are small stones that form in the glands that make saliva, usually the gland under the jaw. A stone can block the flow of saliva, so the gland swells and becomes painful, especially at mealtimes. They are not usually serious.

What it is

Small stones often pass by themselves. Drinking plenty of water, sucking sour sweets, and massaging the gland can help.

If a stone does not pass, it can be removed with a small procedure. Antibiotics are needed if the gland becomes infected.

Common signs

  • Pain and swelling under the jaw or in the cheek
  • Symptoms worse when eating
  • A small lump under the tongue
  • A bad taste in the mouth
  • Redness and pus if infected

How it is usually diagnosed

  • Examination of the mouth and neck
  • Ultrasound scan
  • Sometimes an X-ray, CT or sialogram

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Ultrasound or scan reports
  • ENT or maxillofacial surgery letters
  • Procedure notes

Questions to ask your doctor

  • Is the stone likely to pass by itself?
  • What can I do at home to help?
  • Would the stone need to be removed?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Swelling spreading to the neck, difficulty swallowing or breathing, or a high temperature: get urgent help, call 112
