Treatment involves finding any correctable causes and fixing those if possible. In many cases it is not possible to correct the xerostomia itself, and treatment focuses on relieving the symptoms and preventing cavities. Patients with xerostomia should avoid the use of decongestants and antihistamines, and pay careful attention to oral hygiene. Sipping sugarless fluids frequently, chewing xylitol-containing gum, and using a carboxymethyl cellulose saliva substitute as a mouthwash may help. Patients who have endured chemotherapy usually suffer from this post- treatment.

How to Control Dry Mouth
 

• Frequently sip water.
• Keep fluids at bedside at night.
• Chew sugarless gum.
• Avoid tobacco, alcohol and foods high in sugar.
• Adjust the air humidity in your home.
• Use a saliva substitute - this is a commercial product which attempts to "wet" the mouth like saliva does; it can be found in most pharmacies.
• Establish a good plaque control program - since heavy plaque accumulations occur with oral dryness.
• Use fluoride - toothpaste, rinse, or gel.
• Dry mouth (xerostomia) can result in oral discomfort and can have serious consequences.
