Sticky saliva means sticky saliva, and the pathologic causes may be acute suppurative parotitis, chronic obstructive parotitis, and Sjögren’s syndrome, etc., as follows. 1. Acute suppurative parotitis: often caused by bacterial infection, the parotid ducts may be overflowing with pus or blocked by pus plugs, which prevents the secretion of saliva, both of which will cause the patient to feel that his saliva has become sticky. 2. Chronic obstructive parotitis: The saliva becomes cloudy and sticky like egg white due to narrowing of the duct system or blockage by stones or foreign bodies. 3. Sjögren’s syndrome: an autoimmune disease in which the salivary gland follicles atrophy, leading to a decrease in salivary secretion, and the patient feels sticky in the mouth and has an abnormal sense of taste, which in severe cases affects the function of speech, chewing and swallowing. There may be other reasons for sticky saliva, so it is recommended to go to the hospital in time.
