Human papillomavirus, or HPV, is best known as a sexually transmitted infection. In the United States, HPV is the most common sexually transmitted disease, with 79 million Americans currently infected, according to the Centers for Disease Control and Prevention. In addition to increasing risk for cervical cancer, HPV is a contributing factor in some cases of oral cancer. Each year an estimated 1,700 women and 6,700 men develop oropharyngeal cancer, which affects the tongue and throat.

Connection between HPV and oral cancer

There are more than 40 strains of HPV that live in the skin and mucosal areas. Some of these affect the genitalia, while others are found in the mouth and throat. Of the strains of oral HPV, only one, called HPV16, increases the risk of oral cancer, the Oral Cancer Foundation reports. A retrospective study conducted found that oral cancer developed an average of 15 years after exposure to HPV, making it a relatively slow-growing form of cancer.

In general, 80% of Americans will have an HPV infection at some point in their lifetimes, while 99% develop no ill effects. Getting oral HPV is associated with multiple sexual partners and engaging in oral sex; however, even some individuals who have been with only one partner may contract the infection. Although overall risk of oral cancer from HPV infection is low, it is essential to be proactive about oral health.

How to prevent HPV-related oral cancer

Scientists continue to study how HPV infections lead to oral cancer, so little is known about the progression of the disease. However, one recent study found that poor oral health, including gum disease and poor oral hygiene, is associated with oral cancer risk. Thus, being vigilant about brushing and flossing your teeth regularly may reduce HPV-related oral cancer. Getting the HPV vaccine also protects against the oral form of the virus.

Another key way to reduce mortality from oral cancer is to have regularly scheduled appointments with at Pediatric Dental Associates. Having Dr. Michelle Slezewski and Dr. Paul Engibous examine your mouth at least two times a year increases the likelihood that a sign of oral cancer, such as a sore or patch, will be detected. If you’re concerned about HPV-related oral cancer, please give us a call at our Anchorage, AK office for advice about oral hygiene and disease prevention.

A lot of patients go at their teeth like they were sanding an old floor—that is to say, way too hard! Brushing too hard is probably the most common mistake patients make in their oral care routine, and it can be detrimental to the gums and teeth.

What can brushing too hard cause?

• Receding gums
• Bone loss around teeth
• Loss of teeth
• Tooth sensitivity, especially to hot and cold
• Worn down enamel

Brushing too hard wears away at your gums, which can lead to the neck of the teeth being exposed. This part of the tooth isn't covered by hard enamel like the rest of the tooth and hence the soft inner layer, or dentin, is exposed. Dentin is very sensitive to hot and cold and much more susceptible to bacterial decay. Once the gums recede due to improper brushing, it’s usually irreversible.

How to brush your teeth properly

You know you're supposed to brush your teeth twice a day, so why not do it right? First and foremost, you should only ever brush with a soft bristled brush—not medium or hard—unless directed otherwise by Dr. Michelle Slezewski and Dr. Paul Engibous. Unless you have braces or specific oral health issues, brushing twice a day for two minutes is usually plenty.

The main purpose of brushing is to remove plaque from your teeth and gums. Plaque is actually soft and is a buildup of bacteria, saliva, and food debris. You really don't need to brush hard to remove it, just make sure you aim your toothbrush at the gum line (where plaque grows) and brush in small circular motions, never a back-and-forth motion.

It's also wise to hold your toothbrush gently. People tend to brush harder the tighter they hold their toothbrush.

Still have questions about proper tooth brushing technique or gum health? Ask any staff member or Dr. Michelle Slezewski and Dr. Paul Engibous during your next visit to our Anchorage, AK office; we'd be happy to help!

Nearly 40,000 people are diagnosed with oral cancer annually in the United States, with more than 8,000 dying every year from the disease. Oral cancer has a higher death rate than many other common cancers, including cervical cancer, testicular cancer, Hodgkin’s lymphoma, and thyroid or skin cancers. The high death rate results from the fact that most oral cancers go undiagnosed until the disease is well advanced and has spread to another part of the body, most often, the lymph nodes in the neck.

Dr. Michelle Slezewski and Dr. Paul Engibous and our team want you to know that cancers of the mouth and throat, which account for about three percent of all cancers in the United States, are largely preventable. However, we want you to know about certain risk factors that affect the likelihood of developing the disease.

• Use of tobacco products including smoking cigarettes, cigars or a pipe, or chewing tobacco all elevate risk for developing oral cancer. Tobacco use especially, is a serious risk factor because it contains substances called carcinogens, which harm cells in your mouth.
• Consumption of alcohol in excess can also increase your risk. If you drink alcohol regularly, you have an elevated risk of getting oral cancer. Alcohol abuse (more than 21 drinks in one week) is the second largest risk factor for the development of oral cancer, according to the Oral Cancer Foundation.
• Excessive sun exposure. People who spend lots of time outdoors and do not use proper amounts of sunscreen or lip balm have a greater risk for developing lip cancer. Exposure to ultraviolet (UV) radiation from sunlight may also cause melanoma, the most serious type of skin cancer.

If you notice unusual lumps, bumps, or red or white patches in your mouth that don’t go away, sores that won’t seem to heal, persistent soreness, or pain or difficulty swallowing please consult Dr. Michelle Slezewski and Dr. Paul Engibous and our team immediately.

Other factors that may influence your risk for developing oral cancer include:

• Age: Oral cancer is typically a disease that affects older people, usually because of their longer exposure to other risk factors. Most patients diagnosed with oral cancer are over the age of 40.
• Gender: Oral cancer strikes men twice as often as it does women.
• A history with viral infections, such as human papillomavirus (HPV)
• A diet low in fruits and vegetables

During your next visit, Dr. Michelle Slezewski and Dr. Paul Engibous will examine your mouth for signs of oral cancer. If you have been putting off a visit to our Anchorage, AK office for your regular checkup, now is an excellent time to schedule one. Regular visits can be the first line of defense against oral cancer because we can identify early warning signs of the disease. Give us a call today!

You’ve heard people tell you to say “cheese” when you’re having your picture taken, probably more times than you can count. There is another reason you should be saying “cheese” … or “YES” to eating cheese.

Although Dr. Michelle Slezewski and Dr. Paul Engibous and our staff routinely encourage our patients to brush their teeth after eating, the one time you don’t want to do that, at least not immediately, is after eating cheese.

Study Finds Important Benefit From Eating Cheese

CBS News reported on the results of a study that was published in the May/June 2013 issue of General Dentistry, a publication of the Academy of General Dentistry. The study showed that cheese increases dental plaque pH, but in this case, the plaque increase isn’t a bad thing. When you eat cheese, you increase the pH of the plaque on your teeth, and create a protective coating that may lower your risk of getting dental caries -- more commonly known as cavities.

An analysis of the story from the General Dentistry journal, including the details of the study and its participants, was published in Science Daily. The study looked at 68 children between the ages of 12 and 15. A similar study was conducted by British researchers who reported their findings in the British Dental Journal in 1999.

How the Study Worked

For the 2013 study, researchers divided kids into three groups. Participants in group one ate cheddar cheese. Participants in group two drank milk, while participants in group three ate sugar-free yogurt. All participants were told to eat or drink their assigned foods for three minutes, after which they swished water in their mouths.

Researchers tested every participant’s mouth at ten, 20, and 30-minute intervals. They found no changes in the mouths of participants in the milk drinking and sugar-free yogurt eating groups, but every time they tested the pH levels in the mouths of the ones who had eaten cheese, researchers saw the levels quickly increased.

They concluded that cheese has anti-cavity properties. That isn’t the only benefit, however. Another study, in which related findings were reported, appeared in the Journal of Contemporary Dental Practice in the summer of 2000. In that study, researchers found that cheese may give teeth a protective coating that helps lessen enamel erosion caused by acidic foods, particularly from sugar-sweetened soft drinks.

So don’t just say cheese for pictures. If you want to have a happy, healthy and long-lasting smile, go for cheese. It’s good for your bones, too!
