TobaccoOneBaseballTraditionWeCanDoWithout

While sports like football, basketball and soccer have exploded in popularity over the last few decades, many Americans still have a soft spot for the granddaddy of them all: baseball. While technology has changed many aspects of the game, many of its endearing traditions live on.

Unfortunately, one baseball tradition isn’t so endearing and definitely hazardous to health—tobacco, primarily the smokeless variety. Players and coaches alike, even down to the high school level, have promoted or at least tolerated its use.

But there are signs this particular baseball tradition is losing steam. Not long ago, the San Francisco Giants became the first major league baseball team to prohibit tobacco in its home stadium—on the field as well as in the stands. The move was largely in response to a law passed by the City of San Francisco, but it does illustrate a growing trend to discourage tobacco use in baseball.

While smoking, chewing or dipping tobacco can certainly impact a person’s overall health, it can be especially damaging to the teeth, gums and mouth. Our top oral health concern with tobacco is cancer: Research has shown some correlation between tobacco use (especially smokeless) and a higher risk of oral cancer.

You need look no further than the highest ranks of baseball itself to notice a link between tobacco and oral cancer. Although from different eras, Babe Ruth and Tony Gwynn, both avid tobacco users, died from oral cancer. Other players like pitcher Curt Schilling have been diagnosed and treated for oral cancer.

Cancer isn’t the only threat tobacco poses to oral health. The nicotine in tobacco can constrict blood vessels in the mouth; this in turn reduces the normal flow of nutrients and disease-fighting immune cells to the teeth and gums. As a result, tobacco users are much more susceptible to contracting tooth decay and gum disease than non-users, and heal more slowly after treatment.

That’s why it’s important, especially in youth baseball, to discourage tobacco use on the field. While most of baseball’s traditions are worthy of preservation, the chapter on tobacco needs to close.

NewSalivaTestmayHelpIdentifyOralCancerEarlier

A half million people are diagnosed every year with oral cancer. While other cancers are more prevalent, oral cancer is among the most dangerous with only a fifty percent five-year survival rate.

A major reason for this low rate is because this fast growing cancer is difficult to detect early — diagnosis comes far too often after the disease has already well advanced. In an effort to detect cancer earlier many dentists visually screen for oral abnormalities during checkups, especially patients over fifty, tobacco or heavy alcohol users, patients with a family history of cancer or a medical history of exposure to the sexually transmitted human papilloma virus, HPV-16.

If they detect an abnormality, the dentist often refers the patient to an oral surgeon or other specialist for a possible biopsy. In this procedure the surgeon removes a sample of the abnormal tissue, which is then examined microscopically for cancer cells. A biopsy remains the most effective way to diagnose oral cancer.

Because of the disease's aggressive nature, many dentists lean to the side of caution when referring patients for biopsy. As a result 90% of oral biopsies reveal no cancer. Reducing the number of biopsy referrals is highly desirable, especially for the patient undergoing the procedure. Tissue samples tend to be large to ensure complete detection of any cancer cells. Depending on the size and location of the sample, there may be a risk for loss of function or disfigurement.

A new screening tool using a sample of a patient's saliva could help reduce the number of biopsy referrals. Besides DNA, saliva also contains dormant genes called biomarkers that activate in response to the presence of a specific disease. This particular saliva test identifies those biomarkers for oral cancer if they're present.

A sample with a low score of biomarkers indicates no cancer present (with a statistical confidence of 99%). A medium or high score indicates cancer may be present, but only a biopsy can determine for sure. Using this test, dentists might be able to reduce the number of biopsy referrals and instead be able to employ watchful waiting in certain cases. Because of its simplicity and non-invasiveness, saliva screening could help identify oral cancer earlier.

ReduceYourRiskofOralCancerwithaHealthyDiet

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.

If you would like more information on dental-friendly nutrition practices, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Diet and Prevention of Oral Cancer.”

ToDetectOralCancerEarlySeeYourDentist

This month marks the 20th annual observance of Oral Cancer Awareness Month. Last year, over 50,000 people in the US were diagnosed with oral cancer, and over 10,000 people died from the disease. The 5-year survival rate for oral cancer is only around 57%, making it more deadly than many other types of cancer. But if oral cancer is caught and treated early, the 5-year survival rate jumps to over 80%. This is one reason why regular dental checkups are so important—we can be your best ally in detecting oral cancer in its early stages.

Oral cancer is particularly dangerous because it often develops without pain or obvious symptoms. Early detection greatly improves the chances of successful treatment, but signs of the disease frequently go unnoticed until the cancer is advanced. Fortunately, dentists and dental hygienists are trained to recognize signs of oral cancer in the early stages, when it is most treatable. Oral cancer can appear on any surface of the mouth and throat, with the tongue being the most common site, particularly along the sides, followed by the floor of the mouth. As part of a regular dental exam, we examine these surfaces for even subtle signs of the disease.

Screenings performed at the dental office are the best way to detect oral cancer, but between dental visits it's a good idea to check your own mouth for any of the following: white or red patches, lumps, hard spots, spots that bleed easily or sores that don't heal. Let us know if any of these symptoms don't go away on their own within two or three weeks.

Using tobacco in any form is a major risk factor for oral cancer, especially in combination with alcohol consumption. Although the majority of people diagnosed with oral cancer are over age 55, the fastest growing segment of new diagnoses are among young people due to the rise in cases of sexually transmitted human papillomavirus (HPV) in young adults.

A routine dental visit can do much more than preventing and treating tooth decay and gum disease—it might even save your life! If you have questions about oral cancer or are concerned about possible symptoms, call us as soon as possible to schedule an appointment for a consultation.

4ReasonswhyQuittingChewingTobaccoisGoodforYourOralHealth

Chewing tobacco is as much a part of our sports culture as the national anthem. What once began as an early 20th Century baseball player method for keeping their mouths moist on dusty fields has evolved into a virtual rite of passage for many young athletes.

But the persona of “cool” surrounding smokeless tobacco hides numerous health threats — including disfigurement and death. What isn’t as widely recognized is the degree to which chewing tobacco can adversely affect your teeth, mouth and gums.

Need more reasons to quit? Here are 4 oral health reasons why you should spit out smokeless tobacco for good.

Bad breath and teeth staining. Chewing tobacco is a prime cause of bad breath; it can also stain your teeth, leaving your smile dull and dingy, as well as unattractive from the unsightly bits of tobacco between your teeth. While these may seem like superficial reasons for quitting, a less-than-attractive smile can also have an impact on your self-confidence and adversely affect your social relationships.

The effects of nicotine. Nicotine, the active ingredient in all tobacco, absorbs into your oral tissues and causes a reduction in blood flow to them. This reduced blood flow inhibits the delivery of antibodies to areas of infection in your mouth. This can cause…

Greater susceptibility to dental disease. Tooth decay and gum disease both originate primarily from bacterial plaque that builds up on tooth surfaces (the result of poor oral hygiene). The use of any form of tobacco, but particularly smokeless, dramatically increases your risk of developing these diseases and can make treatment more difficult.

Higher risk of oral cancer. Besides nicotine, scientists have found more than 30 chemicals in tobacco known to cause cancer. While oral cancer constitutes only a small portion of all types of cancer, the occurrence is especially high among smokeless tobacco users. And because oral cancer is difficult to diagnose in its early stages, it has a poor survival rate compared with other cancers — only 58% after five years.

The good news is, you or someone you love can quit this dangerous habit — and we can help. Make an appointment today to learn how to send your chewing tobacco habit to the showers.
