WHAT TO KNOW ABOUT XEROSTOMIA
Xerostomia, more commonly known as dry mouth, is a condition related to the salivary glands, which help keep the mouth moist, thus preventing decay and other oral health problems. When the salivary glands do not work properly, the amount of saliva in the mouth decreases, resulting in xerostomia. Everyone has a dry mouth once in a while, but if you often find that your mouth is dry, it could be a sign of certain diseases and conditions, according to the National Institute of Dental and Craniofacial Research.
What causes dry mouth?
Prescription and over-the-counter medications are the most common cause of dry mouth. There are more than 400 medications that can contribute to mouth dryness, including antihypertensives, antidepressants, painkillers, tranquilizers, diuretics, and antihistamines. Dry mouth also can be caused by radiation therapy and chemotherapy, hormonal alterations or other diseases, such as diabetes, lupus, Sjogren's, Alzheimer’s, and kidney disease. Other contributing factors include age, stress, anxiety, depression, nutritional deficiencies and dysfunction of the immune system.
How important is saliva?
Saliva is a natural defense for teeth and is vital to everyday processes such as tasting, swallowing, speaking and digesting. Without it, teeth are vulnerable to tooth decay and bacterial, fungal and viral infections. Human saliva is composed mostly of water, but also includes electrolytes, mucus, antibacterial compounds and various enzymes. The components of saliva play a major role in keeping your mouth healthy by rinsing away food particles, neutralizing harmful acids and providing enzymes to help digest food.
