Dry Mouth (Xerostomia) Causes and Treatment

Dry Mouth (Xerostomia) Causes and Treatment

Does your mouth feel dry and sticky when you first wake up in the morning? Do you feel the urge to drink lots of water? Dry mouth, or xerostomia, is a condition which slows or prevents saliva production. It can make it hard for you to swallow, chew your food or speak clearly. Dry mouth can contribute to tooth decay, causing it to progress very quickly. Untreated, dry mouth can also contribute to bad breath.


Dry mouth (xerostomia) can be caused by the medicine you take, both prescription and over-the-counter. Don't stop taking your medication, but mention dry mouth to your physician or dentist. Dry mouth can also be a sign of diseases and other conditions like diabetes - so make sure you tell your medical or dental professional about dry mouth if it becomes a problem for you.


  • Dry or sticky feeling in the mouth like your mouth is stuffed with cotton balls.
  • Burning feeling in mouth or tongue and sometimes tongue feels like shoe leather.
  • Difficulty or discomfort when chewing, swallowing or speaking.
  • Dry lips and throat or mouth sores.

  • Sip room-temperature water throughout the day and night and carry a water bottle with you at all times.
  • Avoid drinking water at an extreme water temperature (very hot or very cold).
  • Only drink sugarless drinks and avoid carbonated beverages.
  • Avoid drinks with caffeine because caffeine can dry out the mouth. Drinking coffee, tea or a diet soda occasionally is OK but don't overdo it.
  • While eating a meal, make sure you include a beverage like water. Drink water before, during and after the meal.
  • Chew sugarless gum or suck on sugarless candy to stimulate salivary flow.
  • Both alcoholic beverages and smoking dry out the mouth and make you more susceptible to gum diseases and oral cancer.
  • Use an alcohol free mouthwash. Read the label and make sure alcohol is not listed as an ingredient.
  • Try using a nighttime humidifier to moisten room air.

Visit your dentist to develop a comprehensive plan for dry mouth treatment and management. This plan may include more frequent trips to the dentist.

In-office dental treatment for dry mouth and its related problems may include topical fluoride treatments, prescription home fluoride, antibacterial/antifungal mouthwashes or other products including Xylitol gum. Diagnostic x-rays may need to be taken more frequently to monitor dental decay. Home-care instructions should be customized according to patient needs.

If you have a persistent dry mouth, you may be at greater risk for fungal or viral infections in your mouth. These ulcerations may also develop from trauma caused by friction of oral tissues against denture clasps, appliances or edges of worn or defective dental restorations.

There are many medications available for use in treating common infections associated with dry mouth.
