Although oral cancer isn't the most prevalent among metabolic diseases, it is one of the most deadly with only a 50% survival rate after five years. That's because it can be difficult to detect in its early stages when treatment is most effective.
That's why prevention to reduce your chances of oral cancer is so important. Many people know quitting tobacco products, including smokeless varieties, and moderating alcohol consumption are key to any prevention strategy. But there's one other factor you should also consider: your diet.
We've learned quite a bit in the last few decades about how certain foods we eat contribute to the cancer disease process. Cancer seems to originate when elements in the body or environment (known as carcinogens) damage DNA, our unique genetic code, on the cellular level. For example, a class of chemicals called nitrosamines is a known carcinogen: we often encounter it in the form of nitrites used to preserve meat (like bacon or ham) or as byproducts in beer, seafood or cheese.
Another form of carcinogen is the unstable molecules produced during normal cellular function called free radicals. But our bodies have a natural neutralizer for free radicals called antioxidants. We obtain these substances in our food in the form of vitamins and minerals. While you can also ingest these in the form of supplements, the best way to obtain them is through a diet rich in plant-based food, particularly fruits and vegetables.
So in addition to lifestyle changes like quitting tobacco or moderating alcohol consumption, make sure your diet is a healthy and nutritious one. Limit your intake of processed foods (especially meats) and increase your portions of fresh fruits, vegetables and dairy products.
And don't neglect practicing effective brushing and flossing each day, along with regular dental cleanings and checkups. All of these healthy practices will greatly decrease your chances for life-threatening oral cancer.

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.

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.
