Oral cancer is one of the more dangerous malignancies people face. But there are ways you can reduce your risk of this deadly disease through changes in lifestyle habits and behaviors.
Two of the better known behaviors for increased oral cancer risk are immoderate consumption of alcohol and the use of tobacco, particularly chewing tobacco and snuff. Eliminating these, especially the latter, can vastly improve your odds of avoiding cancer. Another factor is a strain of the human papilloma virus (HPV 16) that's transmitted sexually, which you can avoid through safe sex practices.
In addition to these lifestyle changes, there's one more you should make to lower your oral cancer risk: adjustments to your diet. Research over the last half century has provided ample evidence of a link between the foods we eat and our risk of all types of cancers, including oral.
The biggest concern is over certain elements in some foods that can damage DNA, the molecular “operating instructions” that regulate the formation and function of our bodies' cells. These elements are collectively known as carcinogens because of their role in cancer formation.
An example of a carcinogen is a group of chemicals called nitrosamines. These form during preservation processes using nitrites in meats like bacon or ham. They're also found in beer or certain preserved fish. To limit your consumption of nitrosamines, you should reduce these and other processed products and replace them with fresh fruits and vegetables, or organic meats and dairy products.
Our DNA can also be damaged by unstable molecules called free radicals that arise during normal cellular function. But there are also substances known as antioxidants that help protect the cells from free radical damage. Many plant-based foods contain nutrients like vitamins C and E that have antioxidant properties, so including them in your diet could help reduce your oral cancer risk.
Several clinical studies over the years have been consistent in their findings that a diet rich in fresh fruits and vegetables can reduce the risk of oral or throat cancers, as well as other forms of cancer. Making changes to your diet in that direction, plus other lifestyle changes, could help you avoid this devastating oral disease.

Office cleanings and other minor procedures are a routine part of regular dental care. For some people, though, a routine visit could put them at slight risk for a serious illness.
The reason for this concern is a condition known as bacteremia. This occurs when bacteria, in this case from the mouth and conceivably during an office cleaning or other routine dental procedure, enters the bloodstream. Although for most people this isn’t a great issue, there’s been concern that bacteremia could further compromise the health of patients with or susceptible to other conditions like endocarditis (heart inflammation), prosthetic joints or compromised immune systems.
This concern grew out of a number of studies in the early 20th Century that seemed to show a link between dental bacteremia and infective endocarditis. At about mid-century it became a common practice to administer antibiotics before dental work (usually 2 grams of amoxicillin or an equivalent about an hour before) to high risk patients as a way of protecting them against infection. The practice later expanded to other health issues, including many heart conditions.
Beginning in 2007, however, guidelines developed jointly by the American Heart Association and the American Dental Association reduced the number of conditions recommended for antibiotic therapy. Based on these guidelines, we now recommend pre-procedure antibiotics if you have a history of infective endocarditis, artificial heart valves, certain repaired congenital heart defects, or heart transplant that develops a subsequent heart valve problem. Patients with prosthetic joints or immune system problems are no longer under the guidelines, but may still undergo antibiotic therapy if believed necessary by their individual physician.
If you have a condition that could qualify for antibiotic therapy, please be sure to discuss it with both your dentist and physician. We’ll work together to ensure any dental work you undergo won’t have an adverse effect on the rest of your health.

Periodontal (gum) disease often involves more than gum inflammation. The real danger is what this bacterial infection may be doing to tissues beneath the gum line—including tooth roots and supporting bone.
Gum disease can do extensive damage to the forked areas where the roots separate from the main tooth body. If one of these areas, known as a furcation, becomes infected, the associated bone may begin to diminish. And you may not even know it's happening.
Fortunately, we may be able to detect a furcation involvement using x-rays and tactile (touch) probing. The findings from our examination will not only verify a furcation involvement exists, but also how extensive it is according to a formal classification system that dentists use for planning further treatment.
A Class I involvement under this system signifies the beginning of bone loss, usually a slight groove in the bone. Class II signifies two or more millimeters of bone loss. Class III, also called a “through and through,” represents bone loss that extends from one side of the root to the other.
The class of involvement will guide how we treat it. Obviously, the lower the class, the less extensive that treatment will be. That's why regular dental checkups or appointments at the first sign of gum problems are a must.
The first-line treatment for furcation involvements is much the same as for gum disease in general: We manually remove bacterial plaque, the main source of infection, from the root surfaces using hand instruments and ultrasonic equipment. This is often followed by localized antibiotics to further disinfect the area and stymie the further growth of the furcation involvement.
We also want to foster the regrowth of lost tissue, if at all possible. Classes II and III involvements may present a challenge in this regard, ultimately requiring grafting surgery to stimulate tissue regeneration.
The best approach by far is to prevent gum disease, the ultimate cause for a furcation involvement. You can reduce your chances of gum disease by brushing and flossing daily to remove disease-causing plaque. Regular dental cleanings and checkups, at least every six months, help round out this prevention strategy.
A furcation involvement could ultimately endanger a tooth's survival. We can stop that from happening—but we'll have to act promptly to achieve the best results.
