Xerostomia, commonly known as dry mouth, is the subjective feeling of oral dryness due to reduced saliva production or altered saliva composition. It affects up to 30% of the population and can significantly impact oral health, quality of life, and overall well-being. Saliva plays crucial roles in digestion, oral health maintenance, and speech.
The prognosis for xerostomia depends on the underlying cause. Medication-induced dry mouth may improve with dosage adjustment or alternative medications. Autoimmune conditions like Sjögren's syndrome require long-term management. Radiation-induced xerostomia may be permanent but can be managed with appropriate treatments. Early intervention and comprehensive care can significantly improve quality of life and prevent complications.
