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 might think David Copperfield leads a charmed life:Â He can escape from ropes, chains, and prison cells, make a Learjet or a railroad car disappear, and even appear to fly above the stage. But the illustrious illusionist will be the first to admit that making all that magic takes a lot of hard work. And he recently told Dear Doctor magazine that his brilliant smile has benefitted from plenty of behind-the-scenes dental work as well.
“When I was a kid, I had every kind of [treatment]. I had braces, I had headgear, I had rubber bands, and a retainer afterward,” Copperfield said. And then, just when his orthodontic treatment was finally complete, disaster struck. “I was at a mall, running down this concrete alleyway, and there was a little ledge… and I went BOOM!”
Copperfield’s two front teeth were badly injured by the impact. “My front teeth became nice little points,” he said. Yet, although they had lost a great deal of their structure, his dentist was able to restore those damaged teeth in a very natural-looking way. What kind of “magic” did the dentist use?
In Copperfield’s case, the teeth were repaired using crown restorations. Crowns (also called caps) are suitable when a tooth has lost part of its visible structure, but still has healthy roots beneath the gum line. To perform a crown restoration, the first step is to make a precise model of your teeth, often called an impression. This allows a replacement for the visible part of the tooth to be fabricated, and ensures it will fit precisely into your smile. In its exact shape and shade, a well-made crown matches your natural teeth so well that it’s virtually impossible to tell them apart. Subsequently, the crown restoration is permanently attached to the damaged tooth.
There’s a blend of technology and art in making high quality crowns — just as there is in some stage-crafted illusions. But the difference is that the replacement tooth is not just an illusion: It looks, functions and “feels” like your natural teeth… and with proper care it can last for many years to come.Â Besides crowns, there are several other types of tooth restorations that are suitable in different situations. We can recommend the right kind of “magic” for you.
