You probably know practicing healthy dietary and lifestyle habits can help prevent tooth decay and periodontal (gum) disease. But good habits could also lower your risk for a more dangerous type of disease — oral cancer.
There are several risk factors for oral cancer, including those you can't do much about like your genetic makeup or unknown elements in the environment. But there are factors you can influence with your actions.
You're probably familiar with the links between tobacco use (both smoked and smokeless) and oral cancer. But excessive alcohol use could also increase your risk, as can risky sexual behavior that could expose you to human papilloma virus (HPV) 16.
And what you eat — or don't eat — could also influence your cancer risk. Research over the last half century has uncovered a link between diet and cancer. Cancer development seems to begin with damage to DNA, the genetic material that “tells” each of our cells what it is and what it does in the body. Substances called carcinogens found in the environment — including the foods we eat — can damage our DNA and open the door for cancer to development.
But some foods also contain elements that protect our DNA from carcinogenic damage. Some of these are known as antioxidants, which protect cells from unstable molecules called free radicals. You'll find antioxidants, as well as other protective substances like fiber, vitamins and lycopene in plant-based foods, particularly fruits and vegetables.
Eating a plant-based diet also means you'll eat fewer foods that contribute to the rise of free radicals like saturated fat, animal protein and nitrates (a chemical that occurs in some food processing). A healthy diet, along with quitting tobacco use and moderating alcohol consumption, will help not only preventing decay or gum disease, it will also drastically lower your risk for oral cancer.

If you’ve noticed a small sore in your mouth, it’s possible you have a non-contagious disease known as lichen planus. Although usually benign, it’s still a good idea to have it examined and monitored.
The condition is so named because its lesions are similar in appearance to lichen, the algae and fungi organism often found on rocks and trees. It’s believed to be a type of autoimmune disease, in which the body treats some of its own cells as foreign and reacts adversely to them. Certain medications and substances may also cause a lichenoid reaction. Besides the inner cheeks, gums or tongue, lichen planus may also appear on other skin or mucous surfaces on the wrists, legs or fingernails.
When it appears inside the mouth it usually resembles a lacy pattern of white lines or ulceration. Gum tissues may become red and inflamed, with some soreness after brushing or eating. Although there’s no known cure for lichen planus, it rarely causes serious problems — in fact, you may not even be aware you have the condition unless pointed out during a dental exam. It may, in time, fade away.
If the lesions do become bothersome (painful, itchy or overly-sensitive), there are some ways to ease discomfort: brushing with a soft toothbrush (to minimize irritation), flossing, and avoiding acidic or spicy foods and beverages which have been known to cause flare-ups. Managing stress is also helpful, and a topical steroid may be prescribed for more severe outbreaks.
Perhaps the greatest concern with lichen planus, though, is it may resemble more serious conditions, particularly oral cancer. The only way to be certain that it is a benign condition is to perform a biopsy on some of the affected tissue. If you notice a problem, be sure to visit us for a complete examination. And regardless of whether you have the condition or not, regular oral cancer screenings, as well as limits on alcohol consumption and stopping use of tobacco, will also reduce your risk of oral cancer.
Odds are if you have a case of lichen planus it isn’t causing you any problems. If it does cause you discomfort, though, you can take steps to ease your symptoms.
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.

Actor Michael Douglas shocked TV audiences across the country when he announced on the David Letterman Show in 2010 that he has stage IV oral cancer. Fortunately, the cancer had not spread and his radiation and chemotherapy treatments were successful. This year, Douglas teamed up with the Oral Cancer Foundation to warn others about the dangers of the disease and the importance of early detection. In particular, he wants younger people to know that even if they don't smoke and drink a lot, as he admitted to Letterman that he did, they are still at risk.
As Douglas states in a PSA he made with the foundation, “the fastest growing segment of the people developing oral cancers are young, non smokers.” That's due to a strain of the Human Papilloma Virus known as HPV16 that can be transmitted through oral sex. So it's important to avoid risky sexual behaviors and to be screened regularly for this devastating disease that claims one life every hour in the U.S., according to the Oral Cancer Foundation.
An oral cancer screening is a simple visual and tactile exam done right here at the dental office. We will feel your neck for lumps and inspect your lips and all inside surfaces of the mouth, including the back of your throat, for any suspicious signs. If any are found, a biopsy (laboratory analysis of a tissue sample) can be ordered.
Most oral cancers are “squamous” (small scale-shaped) cell carcinomas that occur in the lining of the mouth and are often preceded by recognizable changes (lesions) of the oral membranes. White or red patches begin to form in the pre-cancerous stage, and as the cancer develops, a non-healing ulcer may appear. If you notice any such changes in your mouth, please let us know.
Michael Douglas ends his PSA with the following plea: “So please, the next time you visit your dentist or your medical doctor, ask for this simple screening. Finding oral cancer in its earliest stages may save your life.” We agree, which is why we always perform this screening during your regular dental check-up. If it's been a while since your last appointment, please come in and see us.
