Good nutrition is vital for maintaining health and preventing disease, especially for your mouth. A diet rich in whole foods — fresh fruits and vegetables, protein and dairy products — and low in sugar will not only promote strong teeth and gums, but lessen your chances of developing tooth decay or periodontal (gum) disease.
Diet is also a prominent factor in reducing the risk for another serious mouth disease — oral cancer. While oral cancer makes up only 3% of total cancer cases reported annually, the five-year survival rate is a sobering 50%, much lower than for other types of common cancers. While genetics plays a role in your susceptibility to oral cancer, lifestyle choices and practices present the greater risk factors for the disease.
Of these lifestyle factors, refraining from tobacco products, moderating your alcohol consumption and avoiding risky sexual behavior are of primary importance in reducing your cancer risk. With that said, you should also take into account the foods that are part of your daily diet — both what you should and shouldn’t eat. As an example of the latter, some foods contain a class of chemicals known as nitrosamines that are carcinogenic (cancer-causing). One such chemical, nitrite, is used as a preservative in meats like bacon or ham, and may also be found in beer, and seafood products.
On the positive side, your diet should be rich in foods that supply antioxidants, substances that protect the body’s cells from damaging, unstable molecules known as free radicals. The best sources for antioxidants (more so than dietary supplements) are plant foods rich in fiber and vitamins C and E. Eating more of these may also reduce your intake of nitrates, animal fat and saturated fat.
Adopting a moderate, nutritious diet, along with exercise, can have a huge positive impact on your general health and quality of life. Along with other lifestyle changes, better dietary choices can also help ensure a healthy mouth and reduce your risk of oral cancer.

Anyone at any age, including older children and teenagers, can lose or be born missing a permanent tooth. And while those missing teeth can be restored, replacing them in patients who haven’t yet reached adulthood can be tricky.
That’s because their dental and facial development isn’t finished. This is especially problematic for dental implants because as the jaws continue to grow, a “non-growing” implant could eventually appear out of alignment with the surrounding natural teeth. That’s why it’s often better to install a temporary restoration until the jaws fully mature in early adulthood. Two great choices are a removable partial denture (RPD) or a bonded (“Maryland”) bridge.
While “dentures” and “teens” don’t seem to go together, an RPD in fact can effectively restore a teen’s lost dental function and appearance. Of the various types of RPDs the one usually recommended for teens has a hard acrylic base colored to resemble the gums, to which we attach prosthetic (“false”) teeth at their appropriate positions on the jaw.
Besides effectiveness, RPDs are easy to clean and maintain. On the downside, though, an RPD can break and—as a removable appliance—become lost. They can also lose their fit due to changes in jaw structure.
The bonded bridge is similar to a traditional fixed bridge. But there’s one big difference: traditional bridges crown the natural teeth on either side of the missing teeth to secure them in place. The supporting teeth must be significantly (and permanently) altered to accommodate the life-like crowns on either end of the bridge.
Instead, a bonded bridge affixes “wings” of dental material extending from the back of the bridge to the back of the natural teeth on either side. While not quite as strong as a regular bridge, the bonded bridge avoids altering any natural teeth.
While a fixed bridge conveniently stays in place, they’re more difficult than an RPD to keep clean. And while less prone to breakage, they aren’t entirely immune to certain stresses from biting and chewing especially in the presence of some poor bites (how the upper and lower teeth come together).
Choosing between the two restorations will depend on these and other factors. But either choice can serve your teen well until they’re able to permanently replace their missing teeth.
One of the top concerns in public health today is exposure to the metallic element mercury within the environment. At abnormal levels, mercury can have a toxic effect on our nervous systems and cause other health problems.
These concerns over mercury have also increased attention on one material in dentistry that has included the metal in its makeup for over a century — dental amalgam for filling teeth. Amalgam is a metal alloy that can include, in addition to mercury, silver, tin, and copper. When first mixed dental amalgam is a moldable material used for fillings in prepared teeth. It then hardens into a durable restoration that can withstand biting forces.
While the use of amalgam has declined with the introduction of life-like colored fillings, it's still used for teeth like molars subject to high biting forces. With what we now know about the ill effects of mercury (which can make up to half of an amalgam mixture) is it safe to continue its use?
The American Dental Association has performed extensive research into amalgam safety. They've found that mercury is stabilized by the other metals in the amalgam. This prevents "free" molecules of mercury, the real source of harm to health, from escaping into the blood stream in the form of vapor. Although trace amounts of mercury vapor from the amalgam are released as a person chews, those levels are well below the threshold that could cause harm.
From a patient standpoint, the biggest drawback to dental amalgam isn't safety — it's the appearance of teeth it's used on. Silver fillings aren't considered attractive. And now there are viable filling alternatives that not only look like natural teeth but can withstand biting forces almost as well as amalgam. These materials include composite resins, mixtures of glass or quartz within resin, or glass and resin ionomers. Each of these has advantages and disadvantages depending on how and where they're applied.
After a thorough dental examination, we'll be able to advise you on what filling material will work best to produce the best result. And if we do suggest dental amalgam you can rest assured it will be a safe choice.
