WTF is Xerostomia?

WTF is Xerostomia?

Xerostomia (n):  Dry mouth.  Occurs when the salivary glands do not make enough saliva (spit) to keep the mouth moist. 


Xerostomia or dry mouth can be a troubling side effect of cancer treatments, especially head and neck radiation. Because saliva is needed for chewing, swallowing, tasting, and talking, these activities may be more difficult with a dry mouth.  Saliva also keeps the mouth clean, helps prevent infection and protects your teeth.  Lack of saliva can increase your risk of developing tooth decay or gum disease.  Ugh! Ugh! and more Ugh!  Although dry mouth cannot be prevented, it can be managed.

Here are some tips for managing dry mouth:

• Sip water throughout the day.  Carrying a bottle of water may help you drink more often.

  • Avoid alcohol, drinks with caffeine, and mouthwashes & other dental products that contain alcohol.  Also stop all tobacco use if you smoke or chew tobacco.
  • Chew sugar-free gum or suck on sugar-free hard candies.
  • Use a cool mist humidifier, especially at night.
  • Rinse your mouth four to six times a day, especially after meals, with a solution of salt and baking soda (a half teaspoon of salt and half teaspoon of baking soda in one cup of warm water).
  • Another option is over-the-counter saliva substitutes.  Look for ones containing carboxymethylcellulose or hydroxyethyl cellulose, such as Biotene Oral Balance.  The Biotene product line includes mouthwash, toothpaste & a chewing gum that has the pH of saliva.

Please remember to always talk with your health care team about any symptoms you experience, including any new symptoms or a change in symptoms.  And if at all possible, visit a dentist at least two weeks before starting radiation treatment or chemotherapy to check the health of your mouth and teeth.

    I was just asking around about this chemo side effect. My mom hates that prescription mouthwash the doc’s gave her. Maybe this will give her some variety. Thanks!

      If this doesn’t work for her, call Dr. Dennis Abbott from @DentalOncology – he’s the BEST and may know how to help her. xo
