CurbingDryMouthCouldBoostYourOralHealthasyougetOlder

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.

Find out how the absence of pain doesn’t always mean that your smile is healthy.

If your smile feels healthy then it must be healthy, right? Wrong! There are issues that can still be happening to your smile without you dental cavitieseven realizing it. That’s why it’s always important to visit one of our Gaithersburg, MD dentists at Kenneth Woo, DDS and Associates every six months for routine care.

Sadly, the idea that all dental cavities cause pain is a myth; so, don’t buy into it! You could still have a cavity and not even know it. Cavities are holes in the enamel of the tooth that can continue to get worse unless treated by one our Gaithersburg dentists.

If the cavity continues to progress it will eventually reach the inside of the tooth, where it will affect the nerves and tissues. This is usually what causes pain. Of course, by then, the cavity has already become a serious problem and the only way to treat the tooth is with a root canal and a dental crown.

But, you can prevent this from happening by following through on those six-month exams and cleanings with us. We can often detect cavities through physical examinations, but once a year we will also run X-rays to help us pinpoint problems that are so small that they aren’t visible. These X-rays can be a real lifesaver when it comes to detecting dental problems like infections or decay. Plus, they are usually found early enough that treatment is far less invasive.

So, if you are experiencing dental pain this is a true dental emergency. This is usually a sign of something more serious going on than just a cavity. And if you think that treatment isn’t necessary until you experience pain this could mean some serious issues for your smile. Remember: prevention is key to maintaining good oral health.

Don’t neglect your smile; turn to Kenneth Woo, DDS and Associates in Gaithersburg, MD for all of your dental needs. Call our office today to schedule your next routine visit. After all, it’s always best to play it safe rather than sorry when it comes to your oral health.

If we could go back in time, we all probably have a few things we wish we could change. Recently, Dr. Travis Stork, emergency room physician and host of the syndicated TV show The Doctors, shared one of his do-over dreams with Dear Doctor magazine: “If I [could have] gone back and told myself as a teenager what to do, I would have worn a mouthguard, not only to protect my teeth but also to help potentially reduce risk of concussion.”

What prompted this wish? The fact that as a teenage basketball player, Stork received an elbow to the mouth that caused his two front teeth to be knocked out of place. The teeth were put back in position, but they soon became darker and began to hurt. Eventually, both were successfully restored with dental crowns. Still, it was a painful (and costly) injury — and one that could have been avoided.

You might not realize it, but when it comes to dental injuries, basketball ranks among the riskier sports. Yet it’s far from the only one. In fact, according to the American Dental Association (ADA), there are some two dozen others — including baseball, hockey, surfing and bicycling — that carry a heightened risk of dental injury. Whenever you’re playing those sports, the ADA recommends you wear a high-quality mouth guard.

Mouthguards have come a long way since they were introduced as protective equipment for boxers in the early 1900’s. Today, three different types are widely available: stock “off-the-shelf” types that come in just a few sizes; mouth-formed “boil-and-bite” types that you adapt to the general contours of your mouth; and custom-made high-quality mouthguards that are made just for you at the dental office.

Of all three types, the dentist-made mouthguards are consistently found to be the most comfortable and best-fitting, and the ones that offer your teeth the greatest protection. What’s more, recent studies suggest that custom-fabricated mouthguards can provide an additional defense against concussion — in fact, they are twice as effective as the other types. That’s why you’ll see more and more professional athletes (and plenty of amateurs as well) sporting custom-made mouthguards at games and practices.

“I would have saved myself a lot of dental heartache if I had worn a mouthguard,” noted Dr. Stork. So take his advice: Wear a mouthguard whenever you play sports — unless you’d like to meet him (or one of his medical colleagues) in a professional capacity…
