Saliva contains enzymes that begin the digestion process. Saliva also cleans the mouth by washing away bacteria and food particles. Saliva keeps the mouth moist and helps to keep dentures or orthodontic appliances (such as retainers) in place.There are three pairs of salivary glands:The two largest are the parotid glands, one in each cheek in front of the earsTwo sublingual glands are under the floor of the mouthTwo submandibular glands are at the back of the mouth on both sides of the jawAll of the salivary glands empty saliva into the mouth through ducts that open at various locations in the mouth.The salivary glands may become inflamed (irritated) because of infection, tumors, or stones.Related topics:Salivary duct stonesSalivary duct tumorsSalivary gland infectionsSymptomsAbnormal tastes, foul tastesDecreased ability to open the mouthDiscomfort when opening the mouthDry mouthPain in the face or mouth painSwelling in front of the earsSwelling of the face or neckSigns and testsTests vary depending on the suspected disorder.TreatmentThe treatment varies depending on the specific disorder.Expectations (prognosis)Most salivary gland disorders respond well to treatment.
