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:
During eating, 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. The submandibular glands, at the back of the mouth on both sides of the jaw, are most often affected by stones.
