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.

Saliva is a true workhorse among bodily fluids — it breaks down food for digestion, keeps harmful bacteria in check and neutralizes acid that is destructive to tooth surfaces. So when saliva flow is chronically diminished, it’s more serious than the uncomfortable feeling of “dry mouth” — it can have a detrimental effect on your overall health.
It’s normal to experience temporary mouth dryness: in the morning (because saliva flow slows during sleep), when we’re under stress, or after smoking or consuming certain foods and beverages like onions or coffee. But chronic dry mouth (“xerostomia”) is different — the mouth remains dry for extended periods, leading to problems like tooth decay caused by inadequate acid neutralization.
Medications are one of the most common causes for xerostomia. According to the Surgeon General, there are over 500 medications — both prescription and over-the-counter — that can cause it, including antihistamines, diuretics and antidepressants. Radiation or chemotherapy used for cancer treatment may also cause dry mouth, sometimes permanently. There are also systemic conditions that affect saliva flow like diabetes, Parkinson’s disease, cystic fibrosis, and many autoimmune diseases.
Treating chronic dry mouth will of course depend on the underlying cause. If drug-related the first approach should be to find a substitute medication that won’t as readily cause reduced saliva flow. If that’s not possible, then it’s helpful to drink more water when taking the medication (a few sips before and a full glass afterward). You can also cut back on caffeinated, acidic or sugary foods and drinks as well as alcohol, and refrain from tobacco use.
A saliva stimulant might also help. Besides prescription medication, there are other products like xylitol, a natural alcohol sugar found in chewing gum, toothpaste or rinses, that help increase saliva flow — and xylitol also inhibits the growth of decay-causing bacteria.
The most important thing for chronic dry mouth is maintaining consistent daily hygiene through brushing and flossing and regular dental cleanings and checkups. Helping to increase your saliva flow and making every effort to prevent dental disease will help keep this condition from harming your teeth and gums.

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.
