Definition: Xerostomia is the clinical term for dry mouth. Why is dry mouth a problem? Saliva is necessary to lubricate the mouth to allow for proper chewing and swallowing. Saliva naturally cleanses the mouth along with protecting the teeth from developing cavities.
Signs and symptoms of xerostomia are:
- Difficulty chewing, swallowing, and speaking
- A dry, burning feeling in the mouth and throat
- A pasty and/or sticky feeling in the mouth
- Dry and chapped lips
- Mouth sores or infection in the mouth
- Bad Breath (halitosis)
What Causes Xerostomia?
The cause of xerostomia may be related to:- Chronic mouth breathing
- Medications used to treat conditions such as high blood pressure
- Medical treatments and procedures such as bone marrow transplants, chemotherapy, and radiation therapy
- Diseases and health conditions such as diabetes, HIV/AIDS, Sjögren’s Syndrome, depression, Parkinson disease, nerve damage, thyroid disease, and dehydration
- A decrease in the production of saliva due to the natural aging processes
How is Xerostomia Treated?
Treating dry mouth is dependent on knowing the cause of the condition in the first place. Your doctor may change your medication if it is suspected to be the cause. Alternatively, medications may be prescribed to increase the production of saliva to help relieve your xerostomia. There are ways to relieve dry mouth such as:
- Sipping water throughout the day and consuming 8 to 10 glasses of water daily to prevent dehydration
- Drinking water or sugar free beverages with each meal to keep food particles from becoming trapped in your mouth
- Sugar-free gum and candy, especially one that has a sour taste, may increase saliva production
- Avoid beverages such as tea, coffee, and alcohol as they may cause a decrease in saliva production
- Avoid smoking as it is a major cause of xerostomia
