Perhaps you haven’t thought of it quite this way, but saliva is one of the true wonders of the human body. This unassuming fluid performs a variety of tasks to aid digestion and help protect your mouth from disease. And you hardly notice it — except when it’s not there.
That’s the case for millions of people in America who have a chronic condition called xerostomia or “dry mouth.” This happens when the salivary glands don’t secrete enough saliva, normally two to four pints daily.
Of course, we can experience mouth dryness when we first wake up (saliva flow ebbs while we sleep), feel stressed, use tobacco, or consume alcohol and certain foods like onions or spices. It becomes a problem, though, when periods of low saliva become chronic. Without its preventive capabilities, you’ll be at much higher risk for dental diseases like tooth decay or periodontal (gum) disease.
Chronic dry mouth can occur for various reasons: systemic diseases like cancer or autoimmune deficiencies can cause it, as well as radiation or chemotherapy treatments. One of the most common causes, though, is medication, both over-the-counter and prescription. The surgeon general identifies over 500 known drugs that may inhibit saliva production, including some antihistamines, diuretics and antidepressants. It’s often why older people who take more medications than younger people suffer more as a population from dry mouth.
Because of its long-term health effects, it’s important to try to boost saliva flow. If your mouth is consistently dry, try to drink more fluids during the day. If you suspect your medication, see if your physician can prescribe a different drug. It also helps to drink a little water before and after taking oral medication.
We may also recommend medication or other substances that stimulate saliva or temporarily substitute for it. Xylitol, a natural alcohol sugar that also inhibits bacterial growth, can help relieve dryness. You’ll often find it in gums or mints.
Chronic dry mouth is more than a minor irritation — it can lead to more serious conditions. In addition to these tips, be sure to also keep up your regular dental visits and maintain a daily schedule of oral hygiene to prevent dental disease.

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.
