While genetics certainly plays a role in a person's susceptibility to various forms of cancer (including oral cancer), there are lifestyle factors that also play a role.
In the case of developing oral cancer, there are a number of prominent lifestyle changes you can make to help reduce your risk: protect yourself from too much sun exposure; avoid the use of any type of tobacco (smoke and smokeless); limit your intake of alcoholic beverages to a moderate level; abstain from risky sexual behavior; and eat a diet rich in fresh fruit and vegetables, as well as other whole foods.
That last lifestyle change not only reduces your level of negative exposure from the environment, it may also provide a positive effect as well. For example, normal cellular function produces unstable molecules known as “free radicals” that can damage the DNA structure within the cell; this could be a precursor to the development of cancer. There are natural substances, however, that can help protect cells against the damage caused by free radicals. These are known as “antioxidants” and they are abundant in many plant-based foods. You, of course, may know them by other names: vitamins, carotenoids (found in red and orange fruits and vegetables) or fiber, to name a few.
A well-balanced diet can provide these and other kinds of cancer-fighting nutrients. And, it's important that you eat the source of these nutrients — fresh plant-based foods. Studies have shown that dietary supplements can't match the effectiveness of actually eating fruit and vegetables.
Besides lowering your cancer risk, a plant-based, whole food diet will also result in better oral health. Diets heavy in processed foods with high amounts of sugar or other bacteria-friendly substances inhibit good oral health.

Did you know that tooth decay (dental caries) is the second most frequently occurring disease — surpassed only by the common cold? It can start as soon as toddlers sprout their first teeth and by middle age, more than 90% of adults are affected by the problem! Fortunately, you can significantly lower your risk for decay. The key is to nurture health-promoting (protective) factors in your mouth while discouraging those that are disease causing (pathologic).
The top two traditional steps can't be stressed enough:
Good Oral Hygiene. Diligent brushing and flossing, along with routine professional cleanings, help limit a buildup of bacterial plaque (biofilm). This whitish film is attractive to decay-producing bacteria (among the many types of bacteria — including beneficial ones — that normally live in the mouth). These microbes like to snack on sugars and carbohydrates (perhaps part of that bagel you had for breakfast or the midafternoon candy bar), and in the process they produce acid. A healthy oral environment has a neutral pH — a perfect balance between acids and bases. But in a more acidic environment, minerals in the protective enamel of your teeth start to dissolve, exposing the dentin and root surfaces underneath that are even more vulnerable.
Sensible Diet. Keep decay-producing bacteria in check by limiting your intake of sugars and carbohydrates; the bacteria need these nutrients to grow and reproduce. Choose products containing natural sugars, such as those in fruits and vegetables, over those containing added sugars, such as sodas and candy. Be aware that Xylitol, an “alcohol sugar” used in some chewing gums and dental products, can actually help reduce pathogenic bacteria. And don't forget that frequent consumption of acidic foods and beverages, such as sipping coffee during the day, can create an acidic environment in your mouth that can contribute to decay by eroding tooth enamel and weakening its defenses.
Individual Risk Factors
You also may have individual risk factors as well that our office can help you identify and address. For example, the shape of everyone's teeth varies and some of us have more valleys, tiny grooves and pits than others. These likely places for bacteria to congregate can be the most difficult to reach with a toothbrush, but invisible sealants can be applied to prevent bacteria from reaching those areas.
