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.

Although a variety of foods provide energy-producing carbohydrates, sugar is among the most popular. It’s believed we universally crave sugar because of the quick energy boost after eating it, or that it also causes a release in our brains of serotonin endorphins, chemicals which relax us and make us feel good.
But there is a downside to refined sugars like table sugar or high-fructose corn syrup: too much in our diets contributes to conditions like cardiovascular disease, diabetes, and dental disease. On the latter, sugar is a primary food source for oral bacteria; the more sugar available in the mouth the higher the levels of bacteria that lead to tooth decay and gum disease.
Moderating your intake of refined sugars and other carbohydrates can be hard to do, given that many processed foods contain various forms of refined sugar. A diet rich in fresh fruits and vegetables helps control sugar intake as well as contribute to overall health. Many people also turn to a variety of sugar substitutes: one study found roughly 85% of Americans use some form of it in place of sugar. They’re also being added to many processed foods: unless you’re checking ingredients labels, you may be consuming them unknowingly.
Sugar substitutes are generally either artificial, manufactured products like saccharin or aspartame or extractions from natural substances like stevia or sorbitol. The good news concerning your teeth and gums is that all the major sugar substitutes don’t encourage bacterial growth. Still, while they’re generally safe for consumption, each has varying properties and may have side-effects for certain people. For example, people with phenylketonuria, a rare genetic condition, can’t process aspartame properly and should avoid it.
One alcohol-based sweetener in particular is of interest in oral care. A number of studies indicate xylitol may actually inhibit bacterial growth and thus reduce the risk of tooth decay. You can find xylitol in a variety of gum and mint products.
When considering what sugar substitutes to use, be sure you’re up to date on their potential health effects for certain individuals, as well as check the ingredients labels of processed foods for added sweeteners. As your dentist, we’ll also be glad to advise you on strategies to reduce sugar in your diet and promote better dental health.

While you do all you can to provide your child healthy meals and snacks at home, they still face tempting choices for unhealthy fare when they’re away. Unfortunately, their school campus could be one of those places with food choices that raise their risk for dental disease.
Thankfully, that situation is beginning to change. The U.S. Department of Agriculture (USDA) issued regulations a few years ago tightening minimum health standards for snacks available on school grounds. Called the Smart Snacks in Schools initiative, it promotes whole grains, fruits, vegetables and low-fat dairy products, while discouraging snacks with empty calories, fat, sugar and excessive salt. This is good news in particular for preventing tooth decay in children and teenagers.
Unfortunately, the initiative may not go far enough. There are a few “loopholes”: it allows for chocolate milk with added sugar as long as it’s fat-free; high schools can also sell beverages like sports and energy drinks, which are low in sugar but high in enamel-harming acid. So, although the general nutrition of snacks in schools may be improving, you should still remain alert to poor choices that may fall through the cracks.
For one thing, you can advocate for better nutrition policies in your child’s school. The USDA initiative is a minimum standard — schools can exceed them and eliminate borderline snacks allowed under the federal regulations.
You can also provide your child snack alternatives to the school vending machine. A little creativity and fun can go a long way: a dash of cinnamon or parmesan cheese on popcorn instead of butter; finger sandwiches made of real cheese on whole-grain bread (with some whimsical shaping with a cookie-cutter); or bite-sized fruits and vegetables like grapes, baby carrots or nuts. The more healthy (and enjoyable) snacks you can send with them, the less chance they’ll turn to a less nutritious choice in the vending machine.
A healthier approach to snacking depends on setting good examples, providing ample selections and accentuating the positive about healthy foods. Choosing nutritious foods, at home and away, is a key building block for healthy teeth and gums.

Refined sugar is a prime food source for disease-causing oral bacteria. As bacteria consume sugar they produce high levels of acid that over time can erode enamel and leave a tooth vulnerable for decay.
The solution to stopping this vicious process is simple: cut back on eating refined sugar. The reality, though, is a bit more complicated. Many of us seem genetically hard-wired with a “sweet tooth,” perhaps a remnant of our early ancestors' sense that sweet foods were a safe means to obtain energy.
Food manufacturers likewise don't help with making this dietary change — the number of items with added sugar has ballooned over the last several decades. We can trace a lot of this back to the unintended consequences of past government guidelines that called for removing fat from processed foods. But this also removed flavor, so manufacturers began adding sugar (under a myriad of names) to compensate.
Sugar consumption is now a hot health topic for its suspected connection with inflammatory diseases like diabetes and cardiovascular disease, as well as dental health. We now have a love-hate relationship with sugar — we want to show it the door but we can't quite bring ourselves to let it go.
The situation has created a market for artificial sweeteners. The amount and types of sugar alternatives has exploded since saccharine first emerged in the early 1960s. With these increased choices, though, there have also been increased concerns over their health impact, including in the mouth.
This concern has prompted numerous research studies. The conclusion: artificial sweeteners don't adversely affect the health of most people. And, from a dental perspective, artificial sweeteners can have a positive impact on teeth and gum health because unlike refined sugar they don't promote oral bacterial growth.
In fact, one particular sweetener may be even more beneficial to your teeth: xylitol. This sweetener, which comes from a sugar alcohol that oral bacteria can't digest, is often found in chewing gums, hard candies or mints. Â In effect, xylitol “starves out” bacteria to help prevent tooth decay.
From a dental perspective, replacing sugar with an artificial sweetener (especially xylitol) can be advantageous. And less sugar could mean more good news after your next dental checkup.
