As adults grow older, oral health concerns change. One common condition that affects seniors is dry mouth. This is a significant concern as 1 in 5 seniors have dry mouth. Dry mouth is not having enough saliva to protect and moisturize our mouth. A dry mouth can quickly lead to serious gum disease, cavities and oral infections.

Causes of dry mouth:

Dry mouth is a known side effect of over 500 medications. A few examples are medications to treat high blood pressure, antidepressants, antihistamines, sedatives and decongestants.

Some diseases cause dry mouth such as diabetes, Sjogren’s Syndrome, Parkinson’s Disease, HIV/AIDS, Alzheimer’s Disease, head and neck radiation and chemotherapy for cancer. Smoking, mouth breathing and dehydration are significant contributors to the diagnosis of dry mouth.

Signs to look for:

  • Dry, irritated cracked lips or the corners of the mouth
  • Cracked and reddened tongue surface
  • Trouble eating or swallowing
  • Problems keeping dentures in place
  • Red, swollen gums
  • Bad breath
  • Thick, ropey saliva

What to do to reduce dry mouth:

Brush teeth with a soft toothbrush and fluoridated toothpaste twice a day. Use floss or an interdental cleaner once a day to clean between the teeth. Use dry mouth products such as Biotene. Consider a prescription-strength fluoride toothpaste (i.e. Prevident 5000), and if you use a mouthwash, make sure it is alcohol free.

To help stimulate saliva and keep the mouth moist during the day:

  • Sip water
  • Use artificial saliva substitutes
  • Sugar free lozenges
  • Chew Xylitol gum

Also, see your dental office or nursing home dental care team as soon as possible. You can also consult your doctor to review current medications.

  • Caffeine
  • Tobacco
