The fact is, according to the Oral Cancer Foundation, close to 40,000 Americans will be diagnosed with oral or pharyngeal cancer this year, resulting in more than 8,000 deaths. Men face twice the risk of developing oral cancer as women, and men who are over age 50 face the greatest risk. The American Cancer Society recommends an oral cancer screening exam every three years for people over the age of 20 and annually for those over age 40. The five-year survival rate is only 50 percent, and oral cancer, which is the sixth-most common diagnosed form of the disease, is one of the few cancers whose survival rate has not improved. Today, Dr. Gregory Weaver and our team would like to take this opportunity to remind all of our patients about the importance of maintaining good oral hygiene to prevent the disease.

So, what can you do at home to take an active role in preventing oral cancer?

The American Cancer Society recommends an oral cancer screening exam every three years for people over the age of 20 and annually for those over age 40. In addition, we encourage you to:

1. Conduct a self-exam regularly. Using a bright light and a mirror, look at and feel your lips and gums. Try tilting your head back to look at and feel the roof of your mouth, and pull your cheeks out to look inside of your mouth, the lining of your cheeks, and your back gums. Pull out your tongue and look at all surfaces. Feel for lumps or enlarged lymph nodes in both sides of your neck and under your lower jaw. Please give us a call immediately if you notice any changes in the appearance of your mouth or any of the signs and symptoms mentioned above.
2. Don’t smoke or use any tobacco products and drink alcohol in moderation.
3. Eat a well-balanced diet. This includes eating a wide variety of foods from the five primary food groups on a daily basis to meet the recommended amounts of vitamins, minerals, carbohydrates, proteins, and fats you need in a given day.
4. Limit your exposure to the sun. Repeated exposure increases the risk of cancer on the lips, especially the lower lip. When out in the sun, be sure to use UV-A/B-blocking sun protective lotions on your skin as well as your lips.

Please let us know if you have any questions about your oral health, either during your next scheduled visit, by giving us a call, or asking us on Facebook.

Our teeth are a lot more complicated than they look. Beneath that shiny white surface is an entire system of different cell tissues working together to keep each tooth vital and healthy.

• Enamel, the protective exterior of the crown (the visible part of the tooth), is the strongest substance in the body and the first line of defense against damage to our teeth.
• Dentin, the hard tissue under the enamel and cementum, has microscopic tubules that connect to the pulp.
• Pulp, the tissue at the center of the tooth, contains the nerves, blood vessels, and connective tissue that keep the tooth alive.
• Cementum, composed of connective tissue which forms the protective exterior of the root, also attaches to fibers in the periodontal ligaments which hold the teeth securely in the jaw.

Because cementum is below the gum line, it’s generally safe from the cavity-causing conditions that our enamel is exposed to every day. But there are still potential hazards that we should be aware of.

• Cementum Erosion

With a name like “cementum,” it’s logical to assume that this is the hardest tissue in the body. Actually, however, that distinction goes to our enamel. And if even our enamel can be damaged by bacteria and plaque, cementum doesn’t stand a chance!

How does cementum come in contact with cavity-causing bacteria? Gums often recede as a natural part of the aging process, leaving part of the root exposed. Gum disease, failure to brush and floss regularly, and heavy-handed brushing can lead to early gum recession. The newly exposed cementum is now exposed to the same conditions, which cause cavities in our enamel. But a root cavity can be trickier to treat and, because the cementum is not as strong as enamel, can progress more quickly. And if a cavity reaches the pulp, a root canal could be necessary.

But the erosion of cementum doesn’t have to result in a cavity to cause discomfort. When cementum is removed, the dentin beneath is exposed. Dentin, you’ll recall, contains tiny tubes that connect to the pulp of the tooth. The result? Conditions such as heat, cold, even an intake of air can cause tooth sensitivity as they stimulate the nerves in the pulp. If your hot coffee or ice cream cone is suddenly causing you pain, let us know. There are treatments, which can reduce tooth sensitivity.

• Gum Disease (Periodontitis)

In more severe cases of gum disease, the gums pull away from the teeth leaving pockets, which harbor plaque and bacteria. Left untreated, these pockets can become home to infections, which attack and destroy bone structure and connective tissue. Caught early, a treatment called tooth scaling and planing can help. In this type of deep cleaning, your dentist or endodontist will remove plaque and tartar and then smooth the root surface to make it harder for bacteria and plaque to stick. If the gums have receded too far, a gum graft might be necessary to protect the exposed roots.

• Trauma

The same traumas that can damage teeth above the gum line can result in injuries below it. Chewing on hard objects (ice, hard candies, wooden pencils), bruxism (tooth grinding), and sports injuries or accidents can cause cracks in the cementum. If your root is split or fractured, it might be possible to save your tooth, but sometimes extraction is the best option.

So how do you protect your cementum, hidden as it is under your gum line? The same way you protect the more visible parts of your teeth!

• Keep to a healthy daily routine of brushing and flossing. This will help prevent gum disease and keep gum recession at bay. Using a soft brush and brushing firmly but gently will remove plaque while protecting both enamel and cementum. If you notice tooth sensitivity, give us a call!
• Come in to our Raleigh, NC office for regular dental exams. The best treatment for gum disease is prevention. When you come in for regular checkups, we are able to discover early signs of gum disease before it becomes a serious problem. If you are suffering from more advanced periodontitis, there are treatments available.
• Safety first when it comes to your smile. If you chew on hard objects, talk to Dr. Gregory Weaver about how to break the habit. If you grind your teeth, see us for solutions. If you play sports, let us know—often a mouthguard can help protect your teeth from injuries that could otherwise lead to more complex procedures or even tooth loss.

Maintaining your healthy dental habits is a lot like cementum—the foundation of a beautiful smile. Nothing complicated about that!

Whether it’s your first child or you’re an experienced mom, pregnancy is an exciting time—which you’ll be able to enjoy much more once the days of morning sickness are over.

Morning sickness affects most pregnant women, and can present in any number of ways. It might take the form of mild nausea, or cause frequent vomiting. It often occurs in the morning hours, but can take place at any time of day. It’s usually over with by the second trimester, or it can last weeks longer. Because of this wide variety of symptoms, morning sickness is more accurately referred to as NVP, the nausea and vomiting of pregnancy.

Your doctor can recommend safe and effective ways to deal with NVP, especially when symptoms are more severe. We have some recommendations to minimize the effect of morning sickness on your dental health.

Wait, dental health? That’s right. Besides its more obvious unpleasant consequences, NVP can cause problems for your teeth and gums. We have a few suggestions for getting you through the weeks of morning sickness with easy and effective strategies to protect your oral health.

Prevent Acid Damage

Vomiting and heartburn with reflux expose the teeth to stomach acids. Tooth enamel is the strongest substance in the body, but it’s not safe from acid attacks.

Normally, the pH balance in our mouths is neutral, around a 7 on a scale of 0 to 14. When acidic conditions lower the oral pH to 5.5 or below, the minerals in enamel begin to dissolve, leading to sensitivity and, eventually, cavities. The pH of our stomach acid ranges from 1.5 to 2.5. This is great for digesting food, but not great at all for enamel and sensitive gum tissue.

Whenever we vomit, the immediate (and understandable!) impulse is to reach for our toothbrushes. But this is an impulse we should resist. Because acids weaken tooth enamel, scouring the teeth with a toothbrush right away can cause more erosive damage. Instead,

• Wait half an hour or more before brushing to give your enamel time to recover its strength.
• In the meantime, rinse with water and perhaps a bit of toothpaste or diluted, doctor-approved mouthwash.

Keep Hydrated

Another consequence of frequent vomiting is dehydration. It’s always important to keep our bodies properly hydrated, and this is particularly true during pregnancy.

Hydration is also essential for oral health. Saliva helps wash away the bacteria and food particles which cause cavities and irritate the gums—especially important now, since pregnancy hormones can leave you more vulnerable to gingivitis and other forms of gum disease.

• Drink water as recommended by your doctor. It’s healthy, it hydrates, and it helps prevent cavities and gum disease. Win/win/win.
• Whichever fluids are your favorites, drinking them in measured amounts through the day will be more effective and more appetizing than drinking large amounts once or twice a day to catch up.
• You have a busy life, so make things easy on yourself. If you need to hydrate more, keep track of your hydration goals with an app or a phone notification. There are even “smart bottles” to track your intake. Or go old school, and fill a bottle marked with timed measurements to remind you to hydrate through your day.

When The Very Idea of Brushing Is Nauseating . . .

When just the thought of brushing is unappetizing, we have suggestions which might help.

• Postpone brushing until later in the day when you feel better. Rinse with water first thing in the morning instead.
• Trade in your regular toothbrush for one with a smaller brush head. This can help prevent the gag reflex.
• Brush slowly, using small strokes.
• If brushing the back teeth is particularly triggering, try deep breathing or sitting down to brush.

We want to help you enjoy a healthy pregnancy. Let us know when you first learn you’re pregnant. We have some valuable tips for the coming months, including suggestions for reducing the dental effects of NVP. Fortunately, morning sickness is temporary, and we’re here with ideas to help your beautiful smile last a lifetime!

“What is the strongest substance in the body?” If this question comes up on trivia night, be prepared to impress your team when you confidently answer, “Tooth enamel!”

Tooth enamel? The reason for this surprising answer lies in the biology of our teeth. Minerals make up well over 90% of our enamel, a much higher percentage than is found anywhere else in the body, including our bones. But unlike bone tissue, which can heal and regenerate, tooth enamel cannot. Even though it is extremely strong, enamel can be damaged by a process called demineralization.

Demineralization

Demineralization is a result of acids at work in our mouths. Acids actually break down the minerals in our enamel, making the enamel softer. Over time, bacteria attack deeper into the tooth, eventually leading to decay. Acidic foods like sodas, citrus, pickles, and coffee are obvious culprits in providing an acidic environment, but there are other problem foods as well. We all have bacteria in our mouths, which can be helpful or harmful. The bacteria in plaque use the sugars and starches we eat to produce even more acids.

This process is something that takes place very quickly. In fact, even brushing too soon after eating something acidic can damage the demineralized surface of a tooth. Waiting at least 20 to 30 minutes to brush gives our bodies a chance to restore the enamel surface in a process called remineralization.

Remineralization

Our bodies are actually designed to help protect our enamel, and the most important part of this process is saliva production. Saliva cleanses our teeth and reduces levels of acidity. And our saliva constantly washes important minerals over our teeth. Calcium and phosphate ions rebuild and strengthen molecules where demineralization has taken place. This process is called remineralization.

We have other ways to help the remineralization process along. Fluoride toothpastes and fluoridated water speed up the movement of mineral building blocks back to the surface of the tooth. Fluoride also strengthens our teeth so that they resist acids and demineralization better than teeth without fluoride, making them less vulnerable to cavities.

New products are available for home and professional use that are designed to increase remineralization—talk to Dr. Gregory Weaver at our Raleigh, NC office if you would like the latest recommendations. In fact, talk to us about tooth-friendly menus, the best toothpastes, brushing techniques, and all the ways to keep your enamel its healthiest. You’ll be answering all those trivia questions with a strong, confident smile!
