Although cancer treatment has advanced steadily in recent decades, the most used therapies continue to be radiation and chemotherapy to eradicate cancerous cells. And while they often work, both can cause "collateral damage" in healthy tissues near the targeted cells.

This can create a number of indirect consequences for a patient's health, including in the mouth. The salivary glands, for example, can be damaged by radiation treatments aimed at the head or neck. The effect on these glands can interrupt the normal flow of saliva and cause xerostomia or "dry mouth."

Lack of adequate saliva causes more than an unpleasant, sticky mouth feeling. One of saliva's main functions is to neutralize acid that builds up naturally after eating. Without it, high acid levels can cause enamel and root surface erosion and lead to tooth decay.

Cancer treatment can also contribute to gastro-esophageal reflux disease (GERD). This disease causes stomach acid to bypass the natural tissue barriers of the esophagus and enter the mouth. As with dry mouth, the increased acid level from GERD can be just as devastating to enamel—and the damage will be permanent.

To minimize these effects on your dental health, it's important to take proactive steps before, during and after cancer treatment. If at all possible, have any needed dental work performed before you begin radiation or chemotherapy—it's better to start it with teeth and gums as healthy as possible.

During treatment, try to continue regular dental visits to monitor your oral health and receive any needed preventive or therapeutic treatments. Depending on your condition and the advice of your dentist, you may need to increase your visit frequency during this time. Your dentist can help with boosting your saliva production and strengthening your tooth enamel. But you should also practice daily brushing and flossing, drink plenty of water and seek treatment for any resulting GERD symptoms.

Even with the best efforts, though, your teeth and gums may still incur damage while treating your cancer. Fortunately, there are a wide array of materials and procedures that can effectively restore them to health. So, once your treatments are completed consult with a dentist on your options for improving the health and appearance of your teeth and gums.

The change from primary teeth to permanent is an announcement to the world that a boy or girl is "growing up." "Growing up," though, is still not "grown"—the new teeth are still in a period of development that can affect how we treat them if they're injured or diseased.

While a new tooth erupts with all its anatomical layers, the middle dentin is somewhat thinner than it will be after it matures. The pulp, the tooth's innermost layer, produces new dentin and gradually increases the dentin layer during this early development period. While the pulp continues to produce dentin over a tooth's lifetime, most of it occurs in these early years.

To prevent or stop any infection, we would normally perform a root canal treatment in which we remove the pulp tissue and fill the empty pulp chamber and root canals. This poses no real issue in an older tooth with mature dentin. Removing the pulp from an immature tooth, though, could interrupt dentin development and interfere with the tooth's root growth. Besides a higher risk of discoloration, the tooth could become more brittle and prone to fracture.

That's why we place a high priority on preserving a younger tooth's pulp. Rather than a root canal treatment, we may treat it instead with one of a number of modified techniques that interact less with the pulp. Which of these we use will depend on the extent of the pulp's involvement with the injury or disease.

If it's unexposed, we may use a procedure called indirect pulp therapy, where we remove most of the tooth's damaged dentin but leave some of the harder portion intact next to the pulp to avoid exposure. If, though, some but not all of the pulp is damaged, we may perform a pulpotomy: here we remove the damaged pulp tissue while leaving the healthier portion intact. We may then apply a stimulant substance to encourage more dentin production to seal the exposure.

These and other techniques can help repair an injured young tooth while preserving most or all of its vital pulp. Although we can't always use them, when we can they could give the tooth its best chance for a full life.

If you're the principal caregiver for an older person, you may have already faced age-related health challenges with them. Good preventive care, however, can ease the impact of health problems. This is especially true for their teeth and gums: with your support you're loved one can have fewer dental problems and enjoy better health overall.

Here are a number of things you should focus on to protect an older person's dental health.

Hygiene difficulties. With increased risk of arthritis and similar joint problems, older people may find brushing and flossing more difficult. You can help by modifying their toothbrush handles with a tennis ball or bicycle grip for an easier hold, or switch them to an electric toothbrush. A water flosser, a device that uses a pressurized water spray to remove plaque, may also be easier for them to use than thread flossing.

Dry mouth. Xerostomia, chronic dry mouth, is more prevalent among older populations. Dry mouth can cause more than discomfort—with less acid-neutralizing saliva available in the mouth, the risk for dental diseases like tooth decay or periodontal (gum) disease can soar. To improve their saliva flow, talk with their doctors about alternative medications that cause less dry mouth; and encourage your loved one to drink more water and use products that help boost saliva flow.

Dentures. If your older person wears dentures, be sure these appliances are being cleaned and maintained daily to maximize their function and reduce disease-causing bacteria. You should also have their dentures fit-tested regularly—chronic jawbone loss, something dentures can't prevent, can loosen denture fit over time. Their dentures may need to be relined or eventually replaced to ensure continuing proper fit and function.

Osteoporosis. This common disease in older people weakens bone structure. It's often treated with bisphosphonates, a class of drugs that while slowing the effects of osteoporosis can cause complications after certain dental procedures. It's a good idea, then, for an older person to undergo any needed dental work before they go on osteoporosis medication.

Keep alert also for any signs of dental disease like unusual spots on the teeth or swollen or bleeding gums. Visiting the dentist for these and regular dental cleanings, checkups and oral cancer screenings could prevent many teeth and gum problems.

November is National Diabetes Month—a time to focus on a disease that affects more than 400 million people around the world. What does diabetes have to do with oral health? Plenty! Here's a true-or-false quiz to test your knowledge on this important topic.

TRUE OR FALSE:

1. Diabetes and gum disease are connected.
TRUE. Studies have found a clear association between diabetes and gum (periodontal) disease, especially when diabetes is not well controlled. People with poorly controlled diabetes have a more severe inflammatory response to the bacteria that cause gum disease. While inflammation is normally a protective reaction of the body's immune system, too much inflammation can actually make the condition worse. In the case of gum disease, the reverse is also true: Untreated gum disease can worsen blood sugar levels in people with diabetes. The good news is that treatment of periodontal disease has been shown to improve blood sugar control.

2. People with diabetes can't have dental implants.
FALSE. Research has shown that dental implants can be a very successful tooth-replacement treatment for people with diabetes. But again, blood sugar control can be a factor. Dental implants are titanium posts that serve as artificial tooth roots. Minor surgery is required to insert an implant into the bone beneath the gums; a realistic-looking dental crown is later attached to it so it can look and function like a natural tooth. Studies have shown that it takes longer for the bone to heal around implants in people with poorly controlled diabetes. That doesn't make implant treatment impossible, but it does mean that it may be managed differently. For example, an implant may be allowed to heal for a longer period of time before a crown is attached to it.

3. People with diabetes can't do anything to improve their oral health.
FALSE. People with diabetes can have a very positive impact on their oral heath, by doing their best to control blood sugar levels with a healthy diet and exercise, and by sticking to an effective daily oral hygiene routine. This includes brushing twice a day for two minutes each time, and flossing at least once each day to remove bacterial plaque between teeth. Regular dental checkups and cleanings are also essential—not just for people with diabetes, but for everyone!

What does November make you think of? Pumpkins? Turkeys? Dry leaves and frosty mornings? How about cigarette butts?

If you’re wondering about the last item, remember that November 15 is the date of the Great American Smokeout—a day set aside for those who want to take the first steps toward quitting the tobacco habit. While the percentage of smokers in the U.S. has dropped to less than 16% in recent years, according to the American Cancer Society there are still some 38 million Americans who smoke cigarettes. Smoking causes over 480,000 deaths every year, and is the leading preventable cause of death in the U.S.

Even if it doesn’t kill you, the effects of tobacco use can be devastating to your entire body—including your mouth. Whether you smoke cigarettes or use chewing tobacco, your risk of oral cancer is greatly increased, as is your chance of developing periodontal (gum) disease. What’s more, smoking can mask the symptoms of gum disease, so your condition is actually worse than it appears. Severe gum disease is one reason why smokers tend to lose more teeth than non-smokers.

In addition, because smoking interferes with the natural healing process, smokers have a much greater chance of dental implant failure. Tobacco use also can lead to increased amounts of plaque, which results in tooth decay and other oral health problems. It also stains your teeth, reduces your senses of smell and taste, and gives you bad breath.

Ready to quit yet? If so, there are lots of resources to help you on the road to a healthier life. The American Cancer Society, sponsor of the Smokeout, can help you make a plan to quit tobacco—and stay off it. It’s not easy, but over a million Americans do it every year. See their website for more information, plans and tips on quitting. Your health care professionals are also a great source of information and help when it’s time to get off the tobacco habit. Feel free to ask us any questions you may have.

And here’s the good news: The moment you quit, your body begins to recover from the effects of tobacco use. In just one year, you’ll have cut your risk of heart attack and stroke in half. After 5 to 15 years, your risk of stroke, coronary heart disease, and several other conditions is the same as someone who has never smoked.
