Dry Mouth (Xerostomia)

Xerostomia (pronounced "zero-sto'me-ah") is the medical word for dry mouth due to decreased or absent saliva. This problem is quite common and is caused by a variety of medical conditions and medications.

Helpful Hints For Treating Dry Mouth

  • Stay Hydrated
    Most people do not drink enough fluids and this will contribute to a dry mouth.
    • Sip cool water throughout the day, let ice chips melt in mouth (don't chew ice!)
    • Drink one-half of your weight in ounces of water per day.
    • Try drinking 2% or whole milk with meals. Milk has moisturizing properties and helps some people to swallow their food.
    • Use a cool air humidifier in your bedroom. Clean and change water daily. Start the humidifier an hour or two before bedtime and let it run through the night. If possible, sleep on your side in order to reduce mouth breathing.
    • For dry lips, use hydrous lanolin USP (Lansinoh), Banana Boat Aloe with Vitamin E lip balm, or Blistex Herbal Answer during the day and especially at bedtime. Chronic use of Vaseline is drying and should be avoided.
  • Restrict Caffeine Intake
    Caffeine is a MAJOR cause of dry mouth. Eliminating caffeine from your diet will have a significant effect on the symptoms of dry mouth.
    • Use caffeine-free tea, coffee and sodas.
    • If you drink caffeine, for every four ounces of caffeine you drink, drink eight ounces of water
  • Avoid Alcoholic Beverages and Mouthwashes
    Alcohol can irritate the tissues and so can foaming agents like sodium lauryl sulfate (SLS).
    • Read labels of commercial products carefully.
    • If you drink alcohol, for every four ounces of alcohol you drink, drink eight ounces of water.
  • Avoid Sugar
    Use sugar-free candy, gum and beverages. Look for products that contain Xylitol, a sweetener that does not cause cavities. Xylitol is found in IceBreakers Ice Cubes, Spry, Theragum, and Epic gum.
    • Overuse of acidic candies and foods can cause a sore mouth.
    • Chewing gum will stimulate saliva flow but look for 6g/day of xylitol.
  • Visit Your Dentist Frequently

    People with dry mouth are more prone to oral yeast infections as well as dental cavities. Excellent hygiene is necessary to prevent cavities and gum disease.
