which condition contributes to dry mouth?
Bad breath can also be caused by dry mouth (known as xerostomia), which occurs when the flow of saliva decreases. Saliva cleanses the mouth and removes particles that may cause odor. Dry mouth is caused by various medications, salivary gland problems or continuously breathing through the mouth. If you suffer from dry mouth, your dentist may prescribe an artificial saliva, or suggest using sugarless candy and increasing your fluid intake. Tobacco products are another cause of bad breath.
