Dry Mouth FAQs – What you Need to Know About Xerostomia

Question 1: What is Dry Mouth, which is called Xerostomia? 

Answer: Dry Mouth—otherwise known as Xerostomia—is a condition where there is a lack of saliva in the mouth. Saliva is essential to keep the mouth moist and keep it lubricated. Without saliva, an individual can experience difficulty speaking, swallowing, chewing and digesting food. This can affect the person’s ability to have normal social interactions, and can cause him or her to withdraw from social activities. In addition, the lack of saliva can make an individual more prone to plaque accumulation, cavities, periodontal disease and oral infection.

Question 2: Who can get Dry Mouth?

Answer: Xerostomia, or dry mouth, is prevalent among seniors. In fact, one third of the population over age 65 experiences xerostomia. In addition, it has been estimated that 30% of all tooth decay in seniors is caused by dry mouth. 

People who undergo radiation and chemotherapy treatment for cancer also encounter serious dry mouth issues. 

Lastly, people who use CPAP machines for sleep apnea also tend to get dry mouth.

Question 3: What general health issues are impacted by Dry Mouth?

Answer: Dry mouth can cause difficulty speaking, fungal infections in mouth, hoarseness, sore throat, difficulties with chewing and swallowing food, burning sensation in mouth, dry nasal passages and difficulty wearing dentures.


Question 4: What are the major Dry Mouth causes?

Answer: The most common types of medication can cause dry mouth including:

• Antihistamines
• Decongestants
• Hypertension meds
• Antidepressants
• Sedatives
• Pain medications
• Parkinson’s diseases meds
• Antacids

Many of these medications cause dry mouth, highly elevating the risk for gum disease and tooth decay because the bacteria sticks to the gums and teeth for longer periods. 

Dry Mouth can also be a main symptom of autoimmune diseases. For example, Sjogren’s syndrome, a chronic inflammatory auto-immune disease, is characterized by dry mouth and dry eyes. More than 4 million people suffer from Sjogren’s, and 9 out of 10 patients are women.

Diabetes is another disease in which dry mouth is often the first symptom. Today, 1 in 4 Americans are diabetic and these cases are seen almost daily. 

Physiological aging also causes xerostomia. While people are living longer due to advances in health care, age-related chronic conditions are increasing, which includes dry mouth. 

Cancer therapy, such as the use of chemotherapy drugs, can change the nature of saliva and the amount produced. Radiation treatments to the head and neck can also damage salivary glands, causing a decrease in saliva production

Drinking alcohol and smoking or chewing tobacco can increase dry mouth symptoms as well. 

Question 5: How can I determine if I have Xerostomia or Dry Mouth?

Answer: To determine if you have dry mouth, it is best to see an experienced dentist like Dr. Raymond Lim at Dental Smiles. To better help him understand your condition, you may want to ask yourself the following questions and inform him of your answers (if he hasn’t already asked you about them)
