Definition of Salivary duct stones
Salivary duct stones are crystallized minerals in the ducts that drain the salivary glands. Salivary duct stones are a type of salivary gland disorder.
Causes, incidence, and risk factors
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.
Signs and tests
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.
The goal is to remove the stone. 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.
Salivary duct stones are uncomfortable, but not dangerous. The stone is usually removed with only minimal discomfort.
