There is much to contend with as we grow older, including a higher risk for dental disease. One possible contributing factor: dry mouth from a lack of saliva.
Also known as xerostomia, dry mouth occurs when the salivary glands secrete less than the normal two to four pints a day. Saliva performs a number of functions, but perhaps the most important for dental health is as an acid neutralizer. Within a half hour to hour after eating, saliva can restore the mouth's normal pH level to prevent acid from softening tooth enamel. When there isn't enough saliva, acid levels stay high leading to erosion of the enamel. This vastly increases the chances for tooth decay.
Although there are several causes for dry mouth, one of the more common is as a side effect from certain medications. It's estimated over 500 drugs — many taken by seniors — can cause dry mouth, including diuretics for high blood pressure and heart failure, antidepressants, and antihistamines. Some diseases like diabetes or Parkinson's may also reduce saliva flow, as well as radiation and chemotherapy.
If you've developed chronic dry mouth, there are some things that may help restore adequate saliva flow. If medication is the cause you can talk to your doctor about an alternative medication or add a few sips of water before swallowing the pills and a full glass afterwards. You should also drink plenty of non-caffeinated beverages (water is the best) during the day and cut back on sugary or acidic foods. And a cool-air humidifier running while you sleep may also help keep your mouth moist.
We may further recommend an over-the-counter or prescription stimulant for saliva. For example, xylitol, a natural alcohol sugar that's found in many gums and mints, has been found to stimulate saliva and reduce the risk of tooth decay as an added benefit.
Last but not least, be sure to brush and floss daily to remove disease-causing plaque and see us at least twice a year for cleanings and checkups (if your mouth is very dry, three to four times a year is a better prevention program). Managing chronic dry mouth along with proper oral hygiene will help ensure your mouth continues to stay healthy as you grow older.

You hardly notice the moist environment of your mouth — unless it becomes uncomfortably dry. Some instances of dry mouth are quite normal — when you first wake in the morning after reduced saliva flow during sleep, when you're stressed, or when you're dehydrated and need fluids. But some are not normal — millions of people, in fact, suffer from a chronic inadequacy of saliva production and flow.
Chronic dry mouth (or xerostomia) can have a greater effect on your oral health than discomfort. Saliva performs a number of tasks for the body: its enzymes help break down food before digestion; its antimicrobial properties help reduce harmful bacteria and its buffering ability helps neutralize acid, both of which reduce the risk of tooth decay.
There are a number of causes for chronic dry mouth. One of the most common arises as a side effect of over 500 medications, both prescription and over-the-counter. The major contributors to dry mouth fall into three main types: antihistamines, used to treat allergies; diuretics, prescribed to cardiac patients to drain excess fluid; and antidepressants. Diseases like Diabetes, Parkinson's disease, or AIDS can also cause dry mouth. Some treatments can too — persons undergoing head or neck radiation or chemotherapy may experience dry mouth.
If you've noticed dry mouth over several days, it's a good idea to visit us for an exam. Our first step is to try to determine the extent and cause of the condition. Depending on what we find, we can then recommend a treatment path that includes some changes in habit and prescribed medications. For example, if lack of hydration is contributing to dry mouth, we would recommend drinking an adequate amount of water, as well as cutting back on caffeinated or acidic beverages. We might also prescribe medication to stimulate saliva flow. Consuming foods that contain xylitol, a natural sugar substitute, may also do the same.
It's also important that you maintain a good oral hygiene regimen and regular dental checkups and cleanings. Good oral hygiene and the proper treatment for chronic dry mouth will greatly reduce your risk of tooth decay and other diseases.
