AStainlessSteelCrownCouldExtendtheLifeofaPrimaryMolar

One of the key elements in a child’s development is their first set of teeth. Although primary (“baby”) teeth last only a few years, they’re critically important for enabling a child to eat solid foods, speak and smile.

But they also provide one more important benefit—they hold the space in the jaw reserved for the permanent teeth developing just under the gums until they erupt. But if a child loses a primary tooth prematurely because of disease or injury, other teeth may drift into the vacant space and crowd it out for the intended permanent tooth. It may then come in misaligned or remain stuck within the gums (impaction).

To avoid this, we try to treat and preserve a diseased primary tooth if at all practical. For a primary molar, one of the large teeth in the back of the mouth, this might include capping it with a stainless steel crown.

Why a metal crown? Primary molars normally don’t fall out until around ages 10-12, so it may be years for a younger child before their permanent molars erupt. All during that time these particular teeth will encounter heavier biting forces than teeth in the front.

A steel crown is often the best solution for a molar given their longer lifespans and encountered biting forces. The crown’s metal construction can stand up to these forces while still protecting the tooth from re-infection from decay. And because molars are typically outside of the “smile zone” occupied by more visible front teeth, the crown’s metal appearance isn’t usually an aesthetic issue.

Crowning a molar usually takes one visit, a dentist typically performing the procedure with local anesthesia and possibly a mild sedative like nitrous oxide gas (“laughing gas”). After removing any decayed structure from the tooth, the dentist will then fit a pre-formed crown over the remaining structure, sized and shaped to match the original tooth as close as possible.

A stainless steel crown is a cost-effective way to added needed years to a primary molar that could otherwise be lost prematurely. Preserving it may help a child avoid bite problems and expensive future treatments.

SteelyDanFoundersDeathHighlightsImportanceofEarlyCancerDetection

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.┬áIf 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.”

DontLetSummerHeatIncreaseYourRiskofDentalDisease

In many parts of the country, summer is often a synonym for "blast furnace" and can be downright hot and miserable. If you find yourself in such a climate, it's imperative that you drink plenty of water to beat both the heat and heat-related injuries. Your teeth and gums are another reason to keep hydrated during those hot summer months.

Your body needs water to produce all that saliva swishing around in your mouth. When you have less water available in your system, the production of this important bodily fluid can go down—and this can increase your risk of dental disease. That's because saliva performs a number of tasks that enhance dental health. It helps rinse the mouth of excess food particles after eating that could become a prime food source for disease-causing bacteria. It also contains antibodies that serve as the first line of defense against harmful microorganisms entering through the mouth.

Perhaps saliva's most important role, though, is protecting and strengthening enamel, the teeth's outer "armor" against disease. Although the strongest substance in the body, enamel has one principal foe: oral acid. If the mouth's normally neutral pH becomes too acidic, the minerals in enamel begin to soften and dissolve. In response, saliva neutralizes acid and re-mineralizes softened enamel.

Without a healthy salivary flow protecting the mouth in these different ways, the teeth and gums are vulnerable to assault from bacteria and acid. As they gain the upper hand, the risk for tooth decay or periodontal (gum) disease can skyrocket. Keeping yourself adequately hydrated ensures your body can produce an ample flow of saliva.

By the way, summer heat isn't the only cause for reduced saliva: Certain prescription medications may also interfere with its production. Chemotherapy and radiation, if targeting cancer near the head or neck, can damage salivary glands and impact flow as well.

If you have reduced saliva from medication you're taking, talk to your doctor about switching to an alternative prescription that doesn't affect saliva production. If you're undergoing cancer treatment, be extra vigilant about your oral hygiene practice and regular dental visits. And as with summer heat, be sure you're drinking plenty of water to help offset these other effects.

Even when it's hot, summertime should be a time for fun and relaxation. Don't let the heat ruin it—for your health or your smile.
