Dry mouth is a condition that many of us have experienced at some point in life. However, for some people it is a problem that can wreak havoc on their lives. This is why we have put together this list of questions we are most frequently asked about dry mouth.
What is dry mouth?
The medical term for dry mouth is “xerostomia” (“xero” – dry; “stomia” – mouth) and it affects millions of people in the US alone. It is caused by an insufficient flow of saliva, the liquid produced by the salivary glands. These glands are located in the inside cheeks of the mouth by the back top molars and in the floor (under the tongue) of the mouth. When functioning properly, they produce two to four pints of liquid every 24 hours.
Can drugs contribute to dry mouth?
Yes, both prescription and over-the-counter (OTC) drugs can cause dry mouth. This is one reason we so often find it in senior citizens, as they are typically on more medications than younger, healthier people.
What about diseases...can they cause dry mouth?
Certain systemic (general body) and autoimmune (“auto” – self; “immune” – resistance system) diseases, in which the body reacts against its own tissue, can cause dry mouth. Other diseases that can be the culprit include: diabetes, Parkinson's disease, cystic fibrosis, and AIDS (Acquired Immune Deficiency Syndrome). Radiation and chemotherapy used to treat head and neck cancers can inflame, damage or destroy the salivary glands—thus causing dry mouth.
Are there any remedies for dry mouth?
Yes! If medication is the primary cause of your dry mouth, there may be other, similar drugs that can be substituted that do not produce the same side effect. If you feel this describes your situation, discuss your concerns with the prescribing physician. Another option is taking an OTC or prescription saliva stimulant to temporarily relieve the dryness. Or, you can suck on a candy made with xylitol, a natural sugar substitute, four to five times a day. Xylitol has been shown to help stimulate the production of saliva with the added benefit of reducing the odds of getting cavities.
A consistently dry mouth is not only uncomfortable and unpleasant but also probably more serious than you think. Dry mouth, medically known as xerostomia (“xero” – dry; “stomia” – mouth) affects millions of people, but few understand why it happens or why it is important.
What Causes Dry Mouth?
It is normal to awaken with a dry mouth because saliva flow decreases at night. But if your mouth is persistently dry throughout the day, it may be a result of habits such as smoking, alcohol or too much coffee drinking or even dehydration. It is also a common side effect of some medications. Xerostomia is not a disease in itself, but it could be a symptom of salivary gland or other systemic (general body) disease.
Why is Saliva Important?
A persistently dry mouth can be a problem. Not only does it feel unpleasant and lead to bad breath, it can also significantly increase your risk for tooth decay. Saliva lubricates your mouth for chewing, eating, digestion and even speaking. Saliva also has important antibacterial activities. Most importantly normal healthy salivary flow neutralizes and buffers acids in the mouth to protect the teeth from the acids produced by bacteria on the teeth that cause decay, and by acids in sodas, sports drinks and juices that can erode tooth enamel.
Not only does saliva neutralize acids but with its high mineral content it can actually reverse de-mineralization — the process by which acids attack enamel and remove calcium from the enamel surface. Healthy saliva actually re-mineralizes the outer layers of tooth enamel, but the process can take 30-60 minutes. That's why it's important not to snack on sugars or drink sodas between meals — one an hour and your mouth is acidic all the time.
Individuals without enough saliva are especially at risk for root decay and fungal infections, and they are also more likely to lose tooth substance through abrasion and erosion.
What Can We Do for a Dry Mouth?
If your mouth is usually dry, make an appointment with us to assess the causes of the problem. However it may be more serious with medical implications. The solution may be as simple as drinking more water and using good daily oral hygiene, or it may necessitate prescription medication to promote more saliva flow.
