    Diseases of salivary glands
Approximate Synonyms
  • Disorder of salivary gland
  • Salivary gland disease
Clinical Information
  • A non-neoplastic or neoplastic (benign or malignant) disorder involving the salivary gland.
  • Condition in which there is a deviation from or interruption of the normal structure or function of any of the three pairs of salivary glands, which are the parotid, sublingual, and submandibular glands.
  • Your salivary glands make saliva - sometimes called spit - and empty it into your mouth through openings called ducts. Saliva makes your food moist, which helps you chew and swallow. It helps you digest your food. It also cleans your mouth and contains antibodies that can kill germs. Problems with salivary glands can cause the glands to become irritated and swollen. This causes symptoms such as
    • bad taste in the mouth
    • difficulty opening your mouth
    • dry mouth
    • pain in the face or mouth
    • swelling of the face or neck
    causes of salivary gland problems include infections, obstruction or cancer. Problems can also be due to other disorders, such as mumps or sjogren's syndrome.
