A result of reduced or no saliva, dry mouth can lead to problems because saliva helps prevent tooth decay by limiting bacterial growth and washing away food particles. Saliva also enhances your ability to taste and makes it easier to swallow. In addition, enzymes in saliva aid in digestion. Patients with a persistently dry mouth may develop a burning or scalded sensation and have poor oral hygiene. They are prone to increased dental caries, periodontal disease, intolerance of dentures and oral infections, particularly candidiasis.
