Dry mouth, also known as xerostomia, is a condition where there is a reduction in the flow of saliva in the mouth. Saliva plays a crucial role in maintaining oral health by helping with digestion, protecting teeth from decay, and keeping the mouth lubricated. When there isn’t enough saliva, the mouth can become uncomfortable and lead to several complications, such as difficulty swallowing, speaking, or tasting food.
Dry mouth can occur due to a variety of reasons, including:
-
Dehydration: Insufficient water intake can cause dry mouth.
-
Medications: Many common drugs, including antihistamines, decongestants, painkillers, and medications for high blood pressure, can reduce saliva production.
-
Health Conditions: Certain medical conditions like diabetes, autoimmune diseases (like Sjögren’s syndrome), and Parkinson’s disease can cause dry mouth.
-
Radiation Therapy: Treatment for cancers of the head and neck can damage the salivary glands, leading to reduced saliva production.
-
Mouth Breathing: Breathing through the mouth, especially during sleep, can dry out the mouth.
-
Aging: As people age, their salivary glands may produce less saliva, especially if they take multiple medications or have other health conditions.
Symptoms of dry mouth include a sticky feeling in the mouth, difficulty swallowing, a sore throat, cracked lips, bad breath, and increased plaque buildup on the teeth. If left untreated, dry mouth can lead to complications such as tooth decay, gum disease, and oral infections.
Treatment for dry mouth typically involves drinking more water, using saliva substitutes, or addressing the underlying cause, such as changing medications or managing a health condition. In some cases, a healthcare provider may prescribe medications that stimulate saliva production.
