Fans of the legendary rock band Steely Dan received some sad news a few months ago: Co-founder Walter Becker died unexpectedly at the age of 67. The cause of his death was an aggressive form of esophageal cancer. This disease, which is related to oral cancer, may not get as much attention as some others. Yet Becker's name is the latest addition to the list of well-known people whose lives it has cut short—including actor Humphrey Bogart, writer Christopher Hitchens, and TV personality Richard Dawson.
As its name implies, esophageal cancer affects the esophagus: the long, hollow tube that joins the throat to the stomach. Solid and liquid foods taken into the mouth pass through this tube on their way through the digestive system. Worldwide, it is the sixth most common cause of cancer deaths.
Like oral cancer, esophageal cancer generally does not produce obvious symptoms in its early stages. As a result, by the time these diseases are discovered, both types of cancer are most often in their later stages, and often prove difficult to treat successfully. Another similarity is that dentists can play an important role in oral and esophageal cancer detection.
Many people see dentists more often than any other health care professionals—at recommended twice-yearly checkups, for example. During routine examinations, we check the mouth, tongue, neck and throat for possible signs of oral cancer. These may include lumps, swellings, discolorations, and other abnormalities—which, fortunately, are most often harmless. Other symptoms, including persistent coughing or hoarseness, difficulty swallowing, and unexplained weight loss, are common to both oral and esophageal cancer. Chest pain, worsening heartburn or indigestion and gastroesophageal reflux disease (GERD) can also alert us to the possibility of esophageal cancer.
Cancer may be a scary subject—but early detection and treatment can offer many people the best possible outcome. If you have questions about oral or esophageal cancer, call our office or schedule a consultation. You can learn more in the Dear Doctor magazine article “Oral Cancer.”
We've known for decades that fluoride strengthens tooth enamel and lowers the risk for decay. And while adding it to toothpaste and drinking water are the more common ways for getting it into the body, an increasingly popular way—especially for children—is to apply fluoride directly to the teeth.
But is topical fluoride really worth the effort and expense? And, are there any side effects to treating teeth this way?
As to the first question, researchers have performed numerous studies measuring fluoride's effectiveness for preventing tooth decay. The Cochrane Oral Health Research Group recently reviewed studies on topical fluoride applications involving nearly 10,000 children and adolescents between the ages of 2 and 15. The combined average for all the studies showed a 28% reduction in decayed teeth for patients who received topical fluoride compared to those who didn't.
This was especially true for children at high risk for decay: directly applying fluoride gels, foams or varnishes to teeth reduces that risk substantially. But there are also side effects to this application. Fluoride in general has only one known safety concern, a condition known as fluorosis. Too much fluoride over time can cause heavy discoloration of the teeth. This does not affect the health of the teeth, but it can look unattractive and require cosmetic treatment to reduce its effect.
There's little to no risk for fluorosis with the controlled treatments offered by dentists; the fluoride solution remains on the teeth no more than a few minutes. But there is a possible side effect during treatment due to the relatively high dose of fluoride used. If the patient accidentally swallows some of the solution, the concentration of fluoride can cause stomach upset, vomiting or headaches.
Dentists minimize the chances for this by usually using the more difficult to swallow varnish form of topical fluoride on younger patients, and using trays or other barrier devices to isolate the fluoride solution from the rest of the mouth. Under professional supervision, it's rare for an accidental ingestion to occur.
The risks for these side effects are quite low, and the benefits of topical fluoride for reducing the chances for decay can more than outweigh them. Fluoride applications are one of many ways we can protect your child's current and future dental health.

We’re all familiar with tried and true traditional braces and perhaps with newer clear aligners for realigning teeth. But there’s an even more novel way that’s quickly becoming popular: lingual braces.
This type of braces performs the same function as the traditional but in an opposite way. Rather than bonded to the front of the teeth like labial (“lip-side”) braces, these are bonded to the back of the teeth on the tongue (or “lingual”) side. While labial braces move teeth by applying pressure through “pushing,” lingual braces “pull” the teeth to where they need to be.
Although lingual braces are no better or worse than other orthodontic methods, they do have some advantages if you’re involved in sports or similar physical activities where mouth contact with traditional braces could cause lip or gum damage, or if your work or lifestyle includes frequent snacking or eating, which requires continually removing clear aligners. And like aligners, lingual braces aren’t noticeable to the outside world.
But lingual braces typically cost more: as much as 15-35% more than traditional braces. They can initially be uncomfortable for patients as the tongue makes contact with the hardware. While most patients acclimate to this, some don’t. And like traditional braces, it’s hard to effectively brush and floss your teeth while wearing them. This can be overcome, though, by using a water flosser and scheduling more frequent dental cleanings while you’re wearing them.
For the most part, lingual braces can correct any poor bite (malocclusion) correctable with labial braces. The treatment time is also comparable, ranging from several weeks to a couple of years depending on the malocclusion. And, as with any other orthodontic method, you’ll need to wear a retainer once they’re removed.
Lingual braces have only been available in a limited fashion for a few years, but their availability is growing as more orthodontists train in the new method. If you’re interested in the lingual braces approach, talk to your orthodontist or visit www.lingualbraces.org to learn more.
