When we don’t keep up with our dental hygiene, plaque buildup can result in three kinds of cavities. Pit and fissure cavities are found on the tops of molars, where food particles get stuck in the irregular surfaces. Smooth surface cavities are located on the smooth sides of teeth.

Wait. Top, all around the sides—what’s left for plaque to attack?

Our roots. The roots of our teeth are generally protected by their concealed position in the jaw. Sitting securely in alveolar bone, held firmly in place by connective tissue, with gum tissue snugly surrounding them, roots are generally not cavity prone.

But these cozy conditions can change. Due to gum disease, abrasive habits, or simply the passage of time, gums can recede and expose root surfaces. And this exposure can lead to root cavities.

If you look at a complete tooth, it looks like enamel is covering the entire tooth surface. In fact, enamel, the strongest substance in the body, only covers the visible part of the tooth, called the crown. The roots are covered by a substance called cementum, which is softer than enamel. And if enamel can’t stop decay, cementum is even more vulnerable when it’s exposed to plaque, bacteria, and acidic foods.

How do we protect our roots from decay? Protecting our gums is the first line of defense.

• Gum Disease

Receding gums caused by periodontitis can be treated by Dr. Gregory Weaver. Deep cleaning procedures such as scaling and root planing can remove accumulated plaque and tartar, and help gum tissue reattach to teeth. For serious recession, gum grafts can replace lost tissue.

Early treatment can prevent recession. If you notice any signs of early gum disease, including bleeding, swelling, tenderness, or persistent bad breath, it’s time for a visit to our Raleigh, NC office.

• Gum Abrasion

It’s not just gum disease that can lead to gum recession. Some personal habits are hard on gums and teeth, and can leave roots exposed. If you bite your nails, grind your teeth, irritate your gums with oral piercings, you are at risk for gum recession. Talk to Dr. Gregory Weaver about preventing abrasive damage.

A surprising cause of receding gums? Over-vigorous brushing. Use a soft-bristled brush—and don’t use a heavy hand when brushing—to protect your delicate gum tissue.

• Aging

As we age, our gums recede. So it’s no wonder that older adults are especially at risk for root cavities. That’s why it’s very important to keep up with brushing (at least two minutes twice a day) and flossing (once a day, or more often if needed) to prevent the buildup of plaque and tartar.

And it’s more important than ever to schedule regular dental exams and cleanings. Dr. Gregory Weaver can help stop small problems from becoming major ones, and suggest brushing and flossing techniques, fluoride treatments, or other procedures to encourage gum and dental health.

If a cavity develops, no matter what kind, it should be treated as soon as possible. And time is especially important for a root cavity.

Because cementum is weaker than enamel, cavities can progress more quickly in roots. A cavity which has reached pulp tissue might require a root canal and a crown to restore tooth function. Serious decay could lead to extraction.

Don’t let root cavities undermine your dental health. If you notice any sign of gum disease or recession, it’s time for a visit to our Raleigh, NC office. After all, even though they go unnoticed, strong roots are the foundation of a healthy, attractive, life-long smile.

Did you know that Human Papilloma Virus (HPV) and oral cancer are linked? This information may prevent you or a loved one from suffering from oral cancer if a diagnosis is made early. Dr. Gregory Weaver and our team want you to understand how you can prevent the spread of oral cancer and protect yourself if you have HPV.

People don’t often speak up about this common virus, but we believe it’s important to educate yourself to prevent the potential spread of oral cancer. According to the Centers for Disease Control and Prevention, up to 80% of Americans will have HPV infections in their lifetime without even knowing it. Symptoms usually go unnoticed, though it’s one of the most common viruses in the U.S. The body’s immune system is generally able to kill the HPV infection without causing any noticeable issues. If you think you might have HPV, talk with primary care physician about getting the preventive vaccine or taking an HPV test.

According to the Oral Cancer Foundation, “HPV is the leading cause of oropharyngeal cancers (the very back of the mouth and throat), and a very small number of front of the mouth, oral cavity cancers. HPV16 is the version most responsible, and affects both males and females.”

Common signs of oral cancer may include:

• Ulcers or sores that don’t heal within a couple of weeks
• Swelling, lumps, and discoloration on the soft tissues in the mouth
• Difficult or painful swallowing
• Pain with chewing
• Persistent sore throat
• Numbness of the mouth or lips
• Lumps felt on the outside of the neck
• Constant coughing
• Earaches on one side of your head

If you experience any of these side effects, please contact Weaver Dentistry as soon as possible.

We hope this information will help you understand the interactions between HPV and oral cancer. Please remember to take precautionary steps if you notice anything out of the ordinary with regard to your oral health. If you have any questions or concerns, contact our Raleigh, NC office.

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!
