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.
There are a few mouth conditions so rare most of us have never heard of them. Geographic tongue would fall into this category, affecting only one to three percent of the population. Even so, these irregular reddish patches resembling land masses on a map (hence the name) might be alarming at first glance—but they pose no danger and usually cause very little discomfort.
Geographic tongue is also known as benign migratory glossitis. As its clinical name implies, the unusual red patchy areas (often surrounded by a grayish white border) aren't cancerous nor contagious. The patches also appear to change shape and move around ("migrate") the tongue.
The reddish appearance comes from the temporary disappearance of tiny bumps on the tongue surface called papillae, which can leave the tongue smooth to the touch in affected areas. The lost papillae may reappear again a few hours or days later, and may occasionally disappear again. While it's not painful, you can experience a stinging or burning sensation emitting from these patchy areas.
We're not sure how and why geographic tongue erupts, but it's believed high emotional or psychological stress, hormonal imbalance or certain vitamin deficiencies might be factors in its cause. There may also be a link between it and psoriasis, a condition that can cause dry, itchy patches on the skin.
If you're one of the rare individuals who has episodes of geographic tongue, the good news is it's harmless, only mildly uncomfortable and usually temporary. The bad news, though, is that there's no known cure for the condition—but it can be managed to ease discomfort during outbreaks.
It's been found that highly acidic and spicy foods, as well as astringents like alcohol or some mouthrinses, can increase the level of discomfort. By avoiding these or similar foods or substances, you can reduce the irritation. Your dentist may also be able to help by prescribing anesthetic mouthrinses, antihistamines or steroid ointments.
For the most part, you'll simply have to wait it out. Other than the mild, physical discomfort, the worst part is often simply the appearance of the tongue. But by watching your diet and other habits, and with a little help from us, you can cope with these irritations when it occurs.

Teeth whitening or bleaching is one of the most affordable and least invasive ways of improving your smile. Although the effect fades with time, whitening can make dull and dingy teeth more attractive in short order.
Teeth whitening is also unique among cosmetic dental procedures in that you can do it yourself at home. While professional bleaching solutions are stronger and capable of greater brightness and longevity, you can still achieve good results with a DIY kit.
If you decide to whiten at home, though, there are a few things to keep mind for a desirable and safe outcome. Here are 3 tips for successful DIY teeth whitening.
Follow the directions. It's not a good idea, both for a successful and safe outcome, to stray away from a kit manufacturer's recommended directions. FDA-approved home kits usually contain 10% or less of carbamide peroxide (one of the more common bleaching agents). That may not seem very strong but it's adequate within the recommended time it remains on your teeth to achieve an effective whitening effect. Exceeding those directions could permanently damage your tooth enamel.
Make sure a home kit will work on your staining. Home whitening kits only affect outer staining on tooth enamel. But dental discoloration can also arise from inside a tooth, often because of trauma, tetracycline use, or as a side effect of a root canal treatment. This kind of internal staining requires a special procedure usually performed by an endodontist to reduce it. So, see your dentist first to make sure your teeth are healthy enough for whitening and that a home kit will work for you.
Get your dentist's advice on home kits. There are a number of whitening applications on the market you can choose, so ask your dentist for recommendations. They can also give you some helpful tips on the whitening process to ensure you'll be safe and successful in your efforts.
Here's a couple of other things to remember to enhance your teeth whitening experience: whether you whiten your teeth at home or with the dentist, be sure you continue to care for your teeth with daily brushing and flossing. And, if you limit your consumption of foods and beverages known to stain teeth, you'll help extend the duration of your brighter smile.
