KeepanEyeonYourFamilysFluorideIntake

Fluoride is a critical weapon in the war against tooth decay. But this natural chemical proven to strengthen tooth enamel has also aroused suspicion over the years that it might cause health problems.

These suspicions have led to rigorous testing of fluoride's safety. And the verdict from decades of research? We've found only one verifiable side effect, a condition called enamel fluorosis. Caused by too much fluoride present in the body, enamel fluorosis produces white streaks and patches on teeth, and can develop into darker staining and pitting in extreme cases. But other than having an unattractive appearance, the teeth remain sound and healthy.

Fortunately, you can reduce the risk of fluorosis by limiting fluoride exposure to within recommended limits. Fluoride can show up in processed foods and other substances, but the two sources you should focus on most are oral hygiene products and fluoridated drinking water.

Dentists highly recommend using toothpaste with fluoride to fight tooth decay. But be careful how much your family uses, especially younger members. An infant only needs a slight smear of toothpaste on their brush for effective hygiene. At around age 2, you can increase the amount to about the size of a vegetable pea.

As to drinking water, most utilities add fluoride to their supply. If yours does, you can find out how much they add by calling them or visiting cdc.gov ("My Water's Fluoride"), where you can also learn more about recommended levels of fluoridation. If you think it's excessive, you can switch to water labeled "de-ionized," "purified," "demineralized," or "distilled," which contain little to no added fluoride.

Even if your fluoridated water is within recommended levels, you may wish to take extra precautions for infants nursing with formula. If possible, use "ready-to-feed" formula, which usually contains very low amounts of fluoride if any. If you're using the powdered form, use only water with the aforementioned labeling for mixing.

Before making any drastic changes that might affect your family's fluoride intake, consult with your dentist first. And be sure you're keeping up regular dental visits—your dentist may be able to detect any early signs of fluorosis before it becomes a bigger problem.

SmokingCouldShortenYourImplantsLongevity

Although costly in the beginning, dental implants often turn out to be the least expensive tooth replacement option. That's because their enviable record for longevity often outpaces dentures or bridges. Over the long-term you might spend less for implants than these other restorations.

But even with the high success rate of dental implants (greater than 95% survive the ten-year mark), we can't guarantee they won't fail. And if you're a tobacco smoker, the risk of failure might be even higher. One study, for example, found early implant failures were twice the rate for smokers over non-smokers. Although implant failures overall are low, smoking seems to be a factor in those that do.

There are a number of reasons to account for this. For one thing, inhaled smoke can damage salivary glands, reducing the flow of this important fluid. Saliva helps control bacterial growth and neutralize mouth acid, so without it you're more susceptible to tooth decay or periodontal (gum) disease. Either infection could ultimately weaken implant-supporting bone.

The nicotine in tobacco can also restrict oral blood vessels and lower their ability to supply antibodies and nutrients to the teeth and gums. This slows healing, which could have one particular effect on implant durability.

During the intervening weeks between implant placement and crown attachment, the implant's titanium post attracts bone cells that grow and adhere to its surface. The effects of nicotine on healing, especially right after implant surgery, can interfere with this integration process so that the implant doesn't anchor in the bone as well as it should.

If you're a smoker, you can increase your chances of implant success—and have a healthier mouth overall—by quitting smoking beforehand with the help of a cessation program. Or at the least, consider stopping smoking for one week before implant surgery and for two weeks afterward.

And be sure to brush and floss your teeth daily and visit your dentist regularly to keep your teeth and gums as healthy as possible. Stopping smoking and practicing effective oral hygiene could make a big difference in the success or failure of your implant.

ReduceYourRiskofOralCancerwithaHealthyDiet

There are a number of lifestyle changes you can make if you want to reduce your risk of oral cancer, with quitting a tobacco habit at the top of the list. You should also moderate your alcohol consumption and practice safe sex to prevent the spread of the human papilloma virus (HPV 16) linked to oral cancer.

And there's one other area that might be ripe for change—your diet. The foods we consume can work both ways in regard to cancer: some, especially processed products with certain chemicals, increase your cancer risk; more natural foods, on the other hand, can help your body fight cancer formation.

Although how cancer forms and grows isn't fully understood, we do know some of the mechanisms involved. One major factor in cancer growth is damage to DNA, the molecule that contains all the instructions for normal cell growth. Certain chemicals called carcinogens cause much of this DNA damage.

One example of these dangerous chemicals are nitrosamines, found in substances used to preserve meats like bacon or ham. Nitrosamines also occur in beer during the brewing process, some fish and fish products, processed cheese and foods pickled with nitrite salt. It's believed long-term consumption of foods with these chemicals can increase the risk of cancer.

On the other hand, there are foods with substances called antioxidants that help our bodies resist cancer. Antioxidants protect cells from unstable molecules called free radicals that can also damage DNA. You'll find antioxidants in abundance in fresh fruits and vegetables, especially those high in fiber. Vitamins like C and E found in many natural foods also have antioxidant properties.

So, to help keep your risk of cancer and other diseases low, make sure your diet includes mostly fresh fruits and vegetables, along with plant-based fats found in nuts or olive oil.  At the same time minimize your consumption of processed foods with preservatives and other chemicals, along with animal and saturated fats.

A change in eating not only reduces your cancer risk, it can also improve your overall health and well-being. You'll also find a healthy diet can be dental-friendly—it can help keep your teeth and gums disease-free and healthy.
