Overview
Salivary duct stones are crystallized minerals in the ducts that drain the salivary glands. Salivary duct stones are a type of salivary gland disorder.
What are the symptoms of Sialolithiasis?
- Difficulty opening the mouth or swallowing
- Dry mouth
- Pain in the face or mouth
- Swelling of the face or neck (can be dramatic when eating or drinking)
What causes Sialolithiasis?
- Saliva (spit) is produced by the salivary glands in the mouth. The chemicals in saliva can crystallize into a stone that can block the salivary ducts.
- When saliva cannot exit a blocked duct, it backs up into the gland, causing pain and swelling of the gland.
- There are three pairs of major salivary glands:
- The two largest are the parotid glands, one in each cheek over the jaw in front of the ears.
- Two submandibular glands are at the back of the mouth on both sides of the jaw.
- Two sublingual glands are under the floor of the mouth.
Diagnosis
An examination of the head and neck by the health care provider or dentist shows one or more enlarged, tender salivary glands. The doctor may be able to feel the stone during examination.
X-rays, ultrasound, or CT scan of the face can confirm the diagnosis.
When to seek urgent medical care?
Call your health care provider if you have symptoms of salivary duct stones.
Treatment options
The goal is to remove the stone.
Drink lots of water and use sugar-free lemon drops to increase the saliva, which may remove the stone. Massaging the gland with heat may help.
The doctor or dentist may be able to push the stone out of the duct. In some cases, the stone may need to be surgically cut out or reduced to small fragments using extracorporeal shock wave lithotripsy.

What to expect (Outlook/Prognosis)?
Salivary duct stones are uncomfortable, but usually not dangerous. The stone is usually removed with only minimal discomfort. Some people may feel more pain.
If the person has repeated stones or infections, the affected salivary gland may need to be surgically removed.
Possible complications
- Discomfort
- Increased risk of salivary gland infections
- Recurrence (coming back) of stones
