Patient EducationClinical

Salivary Gland Disorders

Your salivary glands are in your mouth. You have three pairs of major salivary glands and hundreds of small (minor) glands. They make saliva (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.
