Posts for tag: dry mouth
Like most people, you’ve no doubt experienced occasional dry mouth as when you’re thirsty or just waking from sleep. These are normal occurrences that usually don’t last long.
But xerostomia or chronic dry mouth is another matter. Not only is this continual lack of adequate saliva uncomfortable, it could increase your risk for tooth decay or periodontal (gum) disease.
What’s more, chronic dry mouth can have a number of causes. Here are 3 common causes and what you can do about them.
Inadequate fluid intake. While this may seem obvious, it’s still common—you’re simply not consuming enough water. This deprives the salivary glands of adequate fluid to produce the necessary amount of saliva. If you’re regularly thirsty, you’ll need to increase the amount of water you drink during the day.
Medications. More than 500 drugs, both over-the-counter and prescription, can cause dry mouth as a side effect. This is one reason why older adults, who on average take more medications, have increased problems with dry mouth. There are some things you can do: first, talk with your healthcare provider about alternative drugs for your condition that are less likely to cause dry mouth; drink more water right before taking your medication and right afterward; and increase your daily intake of water.
Diseases and treatments. Some systemic diseases like diabetes or Parkinson’s disease can lead to xerostomia. Autoimmune conditions are especially problematic because the body may turn on its own tissues, the salivary glands being a common target. Radiation or chemotherapy treatments can also damage the glands and lead to decreased saliva production. If you have such a condition, talk with your healthcare provider about ways to protect your salivary glands.
You can also ease dry mouth symptoms with saliva boosters like xylitol gum or medications that stimulate saliva production. Limit your intake of caffeinated drinks and sugary or acidic foods. And be sure you stay diligent with your oral hygiene habits and regular dental visits to further reduce your risks of dental disease.

If you were asked to identify the number one mouth problem affecting dental health, what would you name? Toothaches? Poor hygiene? Jaw joint issues?
Believe it or not, the top issue among 15,000 respondents in a recent American Dental Association (ADA) survey was dry mouth. A full one-third of the respondents had experienced chronic lack of normal saliva flow; difficulty biting and tooth pain, took second and third place, respectively.
We’ve all experienced the discomfort of temporary dry mouth when we first wake up in the morning or after eating certain foods. But chronic dry mouth is much more serious with long-term effects on a person’s teeth and gum health. This is because among its other important properties, saliva helps neutralize enamel-softening mouth acid and restores minerals to enamel after acid contact. Without sufficient saliva flow you’re much more susceptible to dental disease.
While there are several causes for dry mouth, perhaps the most common is as a side effect to at least five hundred known medications. Because older people tend to take more medications than other age groups, dry mouth is an acute problem among people over 60 (a major factor for why dry mouth took the survey’s top health problem spot).
You can help ease dry mouth from medications by first asking your doctor about switching to alternative medications that don’t affect saliva production. If not, be sure to drink more water during the day and especially when you take your oral medication (a few sips before and after).
You can help your dry mouth symptoms from any cause by drinking more water, limiting your consumption of alcohol or caffeine, and avoiding tobacco products. You can also use substances that stimulate saliva flow—a common one is xylitol, an alcohol-based sugar that’s used as a sweetener in certain gums and candies. Not only does xylitol boost saliva flow it also inhibits the growth of bacteria and thus decreases your risk of disease.
And speaking of reducing bacteria and their effects, don’t neglect daily brushing and flossing. These habits, along with regular dental cleanings and checkups, will benefit you just as much as your efforts to reduce dry mouth in avoiding 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.
