Treatment

Treatment of xerostomia includes relieving symptoms and increasing the flow of saliva. Chewing sugar-free gum or candies can increase saliva production. Using a saliva substitute, avoiding caffeine and alcohol, avoiding smoking, and drinking water throughout the day also can help relieve symptoms. With proper treatment, xerostomia can improve. Dry mouth increases the risk of tooth decay. Good dental hygiene and fluoride treatments from a dentist will reduce the risk.
