Knowra Xerostomia Xerostomia Xerostomia is the subjective sensation of oral dryness. It can occur with reduced saliva production or altered saliva composition, but perceived dryness does not always match measured flow.
Salivary glands : Exocrine glands that produce saliva and release it into the mouth. Their secretory output is the main physiological source of oral moisture.
Medication-induced xerostomia : Oral dryness associated with medicines that reduce salivary secretion or alter oral sensation. Medication effects are a frequent and potentially reversible source of dry-mouth symptoms.
Sialometry : Measurement of saliva production, usually by collecting saliva over a set interval. It helps distinguish subjective dryness from objectively reduced salivary flow.
Dysgeusia : A distortion or impairment of the sense of taste. Altered taste can accompany dry mouth but describes a different sensory complaint.
Dysphagia : Difficulty moving food or liquid from the mouth to the stomach. Insufficient lubrication can make swallowing dry foods uncomfortable or difficult.
Saliva : The fluid in the mouth that lubricates tissues, begins digestion, and protects teeth. Changes in its amount or composition can shape the sensation of dryness.
Sjögren syndrome : An autoimmune disease that commonly damages salivary and tear glands. This systemic cause can produce persistent dryness in both the mouth and eyes.
Oral examination : Clinical inspection of the mouth, teeth, gums, tongue, and related tissues. Findings such as tissue dryness, candidiasis, or tooth decay can reveal consequences and clues to cause.
Burning mouth syndrome : A chronic oral pain condition characterized by burning or altered sensations without an explanatory lesion. It can include perceived dryness even when salivary flow is normal.
Dysarthria : Impaired speech production caused by weakness or poor coordination of speech muscles. A dry mouth can make articulation uncomfortable, though it does not itself cause dysarthria.
