Since the 1950s fluoride has played an important role in the fight against tooth decay as an additive to hygiene products and many public water supplies. But although a proven cavity fighter, some have questioned its safety over the years.
To date, though, the only substantiated health risk from fluoride use is a condition known as enamel fluorosis, which occurs when too much fluoride is ingested during early tooth development as the mineral embeds in the tooth structure. Fluorosis can cause changes in the enamel’s appearance, ranging from barely noticeable white streaking to darker visible staining and a pitted texture.
Fluorosis is primarily a cosmetic problem and not a serious health issue. The staining on otherwise sound teeth, however, is permanent and more severe cases may require extensive bleaching treatment to improve appearance. The best strategy is to prevent fluorosis by monitoring and limiting your child’s fluoride intake, until about age 9.
Tooth decay is a more serious condition than fluorosis so we’re not advocating you eliminate fluoride but that you keep your family’s intake within safe levels. The first step is to determine just how much that intake is now, particularly if you drink fluoridated water. If you have public water, you may be able to find its fluoridation level online at apps.nccd.cdc.gov or call the utility directly.
You should also be careful about the amount of toothpaste your child uses to brush their teeth. Children under two need only a trace (a “smear”) on the brush, and children between the ages of 2 and 6 a pea-sized amount. And, they should brush no more than twice a day.
Another possible concern is infant formula, especially mixable powder. While the formula itself doesn’t contain fluoride, water mixed with it may. If you live in an area with increased fluorosis risk, consider breast-feeding (breast milk has little fluoride), using ready-to-feed formula, or mixing powdered formula with bottled water labeled “de-ionized,” “purified,” “demineralized” or “distilled.”
We’ll be glad to help assess your family’s current fluoride intake and advise you on making adjustments to bring it into normal ranges. Taking in the right amount of fluoride assures you and your children receive the most benefit and protection from it, while avoiding future smile problems.

The traditional way to restore a tooth with an artificial crown takes several weeks and multiple office visits: from tooth preparation and impression molding to crown production by a dental laboratory, followed by adjustments and cementing. Now, there’s an alternative that reduces this process to a fraction of the time, and all from your dentist’s office.
Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) is a digital system that enables dentists to create dental restorations with laboratory-grade materials in minutes rather than weeks. As it continues to innovate, you’ll see more and more dentists investing in the new technology for their patients.
A crown restoration with CAD/CAM begins like any other with decay removal and preparation of the tooth. It diverges, though, from the traditional in how an impression of your teeth and gums is obtained: instead of rubber-like molding materials to create a physical impression, we lightly dust the mouth interior with a reflective powder. Using a scanning wand, the reflective powder allows us to capture multiple, detailed images of your mouth that the CAD/CAM computer transforms into an accurate three-dimensional model.
We use the model to first assess if the tooth has been effectively prepared for a restoration. If so, the design feature of the system will provide us with thousands of tooth forms to choose from to match with your natural teeth. You’ll be able to view the proposed size and shape of the new crown via computer simulation before signing off on the design.
Next is the actual manufacture of the crown that takes place right in the dentist’s office. A pre-formed block of ceramic material is inserted in the milling equipment where, following the pre-determined computer design, the milling heads carve the ceramic block. After milling, we fine-tune the crown surface and apply stains or glazes fired to create a life-like color and texture that matches your natural teeth. We can then adjust the crown in your mouth and permanently affix it to the tooth.
While much of the CAD/CAM system is automated, ultimate success still depends on the dentist’s expertise and artistry. CAD/CAM enhances those skills with greater precision and in much less time than traditional crowns. It’s certainly a growing option for many people to restore the form and function of decayed teeth.

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.”
While some aspects of regular dental visits are much the same for everyone, they can be more involved for an older adult. That’s because people later in life face an increased risk of dental disease and other age-related issues.
If you’re a caregiver for an older adult, you’ll want to be aware of these heightened risks. Here are 4 areas of concern we may check during their next regular dental visit.
Oral cancer. While it can occur at any age, cancer is more prevalent among older adults. Although rarer than other cancers, oral cancer’s survival rate is a dismal 50% after five years. This is because the disease is difficult to detect early or is misidentified as other conditions. To increase the odds of early detection (and better survival chances) we may perform a cancer screening during the visit.
Dental disease. The risks for tooth decay and periodontal (gum) disease also increase with age. A primary risk factor for older people is a lack of adequate saliva (the mouth’s natural disease fighter) often caused by medications or systemic conditions. We’ll watch carefully for any signs of disease, as well as assess their individual risk factors (including medications) for decreased oral health.
Dentures. If they wear dentures, we’ll check the appliance’s fit. While dentures can wear with use, the fit may also grow loose due to continuing bone loss in the jaw, a downside of denture wearing. We’ll make sure they still fit comfortably and aren’t stressing the gums or supporting teeth. It may be necessary to reline them or consider replacing them with a new set.
Oral hygiene. Brushing and flossing are just as important for older adults as for younger people for preventing dental disease, but often more difficult due to mental or physical impairment. We can note areas of bacterial plaque buildup and recommend ways to improve their hygiene efforts.
Depending on how well your older adult can care for themselves, it may be advisable for you to come with them when they visit us. Our dental team can provide valuable information and advice to help you help them have a healthier mouth.

Eating is one of the pleasures — and necessities — of life, but people who suffer from temporomandibular joint disorders (TMD) may find eating no pleasure at all — and they may not be eating the right nutritional balance of foods.
TMD is a collection of conditions that affect the jaw joints, connecting muscles and other related facial structures. If you've been diagnosed with TMD, you're probably not only acquainted with severe pain, but also difficulty opening your jaw as widely as normal. This can make it difficult to chew certain foods.
There are a number of effective treatments for TMD, including thermal therapy (hot or cold packs), joint exercise, medication or surgery (as a last resort). But these treatments often take time to make a noticeable difference. In the meantime, you may still need to change what and how you eat to ensure you're getting the nutrients your body needs.
The overall strategy should be to soften and reduce the chewing size of your food. With fruits and vegetables, you'll want to peel and discard any hard or chewy skins, and then chop the fruit flesh into smaller pieces. Steam or cook vegetables like greens, broccoli or cauliflower until they're soft and then chop them into smaller portions. You might also consider pureeing your fruit (and some vegetables) to make smoothies with ice, milk or yogurt, or vegetable-based soups.
Treat meat, poultry or seafood in much the same way, especially biting sizes. Besides cooking meats to tenderness, include moisteners like broths, gravies or brazing liquids to further make them easier to chew.
Dairy foods are an important source of nutrition: eat milk-based products like yogurt or cheese as much as you can handle. If you have problems with these or also nut butters, then consider meal replacement beverages like instant breakfast or whey protein beverages.
And don't forget whole grains. Although some can be hard to chew, you can prepare them in hot cereal form (like oatmeal) to tenderize them. You can also prepare thin bread toast and cut into smaller pieces.
Hopefully, your treatment will bring your TMD symptoms under manageable control. Until then (and after, if need be) adjust your diet to eat the foods that keep you healthy.
