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.

Statistically speaking, Americans can expect to enjoy a longer life today than at any time in the past. A recent U.S. government interagency study indicated that our oldest citizens are also generally getting healthier and doing better economically. Yet, along with an increased lifespan comes the possibility that at some future time, you or a loved one may undergo treatment for cancer.
There's good news here too: According to the National Cancer Institute, a branch of the National Institutes of Health, both the rate of cancer incidence and the death rate from the disease have been steadily declining. It's true that cancer treatments may cause a variety of oral health problems. But did you know that there are some measures you can take to minimize the discomfort and possible complications from these lifesaving therapies?
Chemotherapy and radiation, two common treatments, work by attacking cancerous cells. However, they can affect normal cells too — including the cells lining the mouth, and the salivary glands. This sometimes results in mouth sores, a dry mouth, and an increased risk of developing dental diseases like tooth decay.
What should you do if you or someone you love needs cancer treatments? The best outcomes can be obtained by a dose of prevention when possible, and by taking a team approach to the treatment.
Oral side effects may be worse if the mouth isn't healthy prior to cancer treatment. So, if there's time, have necessary dental procedures done before treatment begins. During and after cancer therapy, dental surgery should be limited if possible. The first step is to get a complete dental examination, and to develop a treatment plan. It's vitally important to coordinate any dental treatments with an oncologist (cancer specialist).
There are also things a patient can do to help control unpleasant oral side effects. Removing the bacteria that cause tooth decay is more essential now than ever. In addition to thorough brushing, an antibacterial rinse or fluoride gel may be prescribed. To combat the symptoms of dry mouth, it's important to drink plenty of fluids. Chewing gum with Xylitol, or using a mouth rinse or a prescription medication may also be recommended.
It's essential for those having cancer treatment to understand and follow the recommendations of their dentist and doctor. These include taking steps to reduce the chance of complications, and recognizing the warning signs that may indicate a problem.

Let's talk about oral cancer. Yes, it's a scary subject — but the truth is, the more you know about it, the better able you are to protect yourself.
- Who is more likely to get oral cancer? Because of your genetic disposition — heredity — men are twice as likely to develop oral cancer as women. African-Americans have a higher incidence than Caucasians. The disease is also related to aging, although in recent years many young people have been diagnosed with this disease.
- Are some habits related to development of oral cancer? Risk factors include use of tobacco in any form, both smoking and chewing, chronic exposure to sun, and consumption of alcohol. Moderate to heavy drinkers have a three to nine times greater risk than non-drinkers. Tobacco smokers are at five to nine times greater risk than non-users, and users of snuff or chewing tobacco are at four times greater risk than non-users.
- Where do most oral cancers occur? The most common areas are in the mouth itself, the lips, the tongue, and the pharynx (back of the mouth and throat).
- What are the statistics for survival after treatment for oral cancer? Conquering cancer depends most on early detection. Since most cases of oral cancer are discovered at a late stage, survival is poor, with less than 60% surviving five years after treatment. When oral cancers are detected early, the survival rate is more than 80%.
- What are some of the symptoms of oral cancer? Most oral cancers are “squamous” (small scale-shaped) cell carcinomas in the lining of the mouth. Signs of these cancers can be seen as white or red patches in the early pre-cancerous stage. These develop into an ulcer that does not heal.
- When should you seek medical help? If you notice color changes (white or red patches) or sores or ulcers anywhere in your mouth that do not heal within two or three weeks, go to your dentist for a checkup right away. Sometimes the sores resemble cold sores. A definitive diagnosis requires a tissue biopsy, in which a small piece of tissue is removed under anesthesia and taken to a lab for microscopic examination.
- What about regular routine examinations? An oral cancer examination should be part of your visit to our office. We will inspect your face, neck, lips and mouth for signs of cancer, feel the floor of the mouth and sides of the neck for any lumps, examine your tongue and the back of your throat. The American Cancer Society recommends a cancer related check-up annually for all individuals aged 40 and older and every three years for those between 20 and 29.
