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.
Pain is the body’s warning system: It tells us something is wrong. And depending on the location and intensity of the pain, it can give us vital clues about the problem.
Sometimes, though, it’s not so clear and direct—the pain could arise from any number of sources. Toothaches often fall into this category: Although it’s likely indicating a tooth or gum problem, it could be something else — or even somewhere else.
This is known as referred pain, in which you may feel pain in one location, like your mouth, but the actual source of the problem is somewhere else, like an infected and congested sinus passage. If we’re able to identify the true source and location of the pain, the better the chances of a successful treatment outcome.
Besides sinus infections, there are other conditions like trigeminal neuralgia that can refer pain to the mouth. This painful condition involves the trigeminal nerve, a large nerve running on either side of the face that can become inflamed. Depending on where the inflammation occurs, you might feel the pain at various points along the jaw, feeling much like a toothache.
There’s also the case of an earache mimicking a toothache, and vice-versa. Because of the proximity of the ears to the jaws, there is some nerve interconnectedness between them. For example, an infected or abscessed back tooth could feel a lot like an earache.
These and other possible problems (including jaw joint disorders or teeth grinding) can generate pain as if it were coming from the mouth or a single tooth. To be sure you’ll need to undergo a complete dental examination. If your dentist doesn’t find anything wrong with your mouth, he or she may refer you to a medical doctor to explore other possible causes.
Getting to the root cause of pain can help determine which treatment strategy to pursue to relieve it. Finding the actual source is the most efficient way to understand what a pain sensation is trying to tell us.
More than 20 million people in the United States use electronic cigarettes or e-cigs as an alternative to tobacco smoking. While many users believe "vaping" is a healthier alternative to regular cigarettes, recent research into the health effects of e-cigs could put a damper on that belief. There's particular concern among dentists that this popular habit could harm users' dental health.
E-cigs are made with a chamber that holds the liquid vaping solution and a heating mechanism to heat the liquid and vaporize it. Users inhale the vapor, which contains nicotine and flavorings, as they would a traditional cigarette.
The nicotine alone can be problematic for dental health as we'll see in a moment. But the vapor also contains aerosols that some research indicates could damage the inner skin linings of the mouth in a similar fashion to the smoke of traditional cigarettes. One study by researchers with the Université Laval in Quebec, Canada found evidence that e-cig vapor increased the death rate of mouth cells, and led to greater cell irregularities over time.
According to other studies, there's evidence that e-cig vapor may disrupt the balance of the oral microbiome, the communities of both beneficial and harmful bacteria that normally live in the mouth. The imbalance in favor of more harmful bacteria could increase the risk for dental disease, particularly periodontal (gum) disease.
Finally, nicotine from e-cigs seemed to create similar conditions in the mouth as it does with tobacco. Nicotine in any form can constrict blood vessels and reduce the body's ability to fight infection and to heal. Research indicates both forms of nicotine increase the risk for dental disease and make treatment more difficult.
These findings only identify conditions created by e-cigs that could be problematic for future dental health. Although we don't fully understand the long-term health effects of this new habit, based on the evidence so far the mouth may not fare so well. It's looking like e-cigs may be no safer for your teeth and gums than the cigarettes they replace.
