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 Marrero 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. Keith J. Fabre Jr. 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!

Decades ago, it was just expected that getting older meant losing teeth. But today’s dental practices and treatments help us defy expectations. How can we keep our teeth healthy as we age? Here are some great habits to continue or begin at any time of life:

• Brush and Floss Regularly

Brushing and flossing two minutes carefully twice a day is a habit we should never break. If using a manual toothbrush has become difficult, an electric model might be just what you need. We also have many suggestions if you have mobility or other issues, so please talk to Dr. Keith J. Fabre Jr. about making regular dental hygiene as comfortable and effective as possible.

• Keep Up with Exams and Cleanings

As we age, gum recession is common. This recession leaves the root areas of our teeth more exposed, and more vulnerable to cavities. Also, old fillings can break or loosen, and cavities can develop around their edges. Keeping a regular schedule of exams and cleanings at our Marrero office helps us discover any problems before they become serious.

• Let Us Know about Changes in Your Health and Medications

If you are taking certain medications, you are at risk for developing a condition called dry mouth, where saliva production greatly decreases. Since saliva washes away the food particles that fuel bacteria growth, reduces acidic elements in the mouth that weaken enamel, and helps fight diseases, dry mouth sets the stage for increased chances of cavities and gum disease. If you are experiencing this condition, we have suggestions for hydration, dental rinses, and sugarless gums that can help.

• Prevent Gum Disease

Regular brushing, professional cleanings, and routine check-ups are the best way to keep your gums healthy. Since untreated gum disease is one of the leading causes of tooth loss in older adults, call us if you have any symptoms such as puffy, red, or swollen gums, bleeding, or persistent bad breath. We can treat periodontitis at any stage, but prevention is always best.

• Don’t Smoke

Studies show a link between smoking and the health of our teeth and gums, as well as a much greater risk of oral cancer. It is never too late to stop smoking! We have suggestions on ways to quit—please let us provide them.

Feel free to talk to us about any concerns you might have. With proper dental care, your teeth can last a lifetime. And that’s a great expectation!

Xylitol tastes sweet, but unlike sugar, it is not converted to acid that can cause your teeth to decay. It’s a naturally occurring sweetener found in plants, fruits, and vegetables; even the human body produces it in small amounts. Xylitol is widely used in sugar-free chewing gum, mints, candies, and even certain forms of medicine.

The World Health Organization has approved xylitol because only a small amount is needed for its health benefits. It’s even safe for diabetics, with a glycemic index of only seven. Xylitol has 40% fewer calories than other types of carbs: less than three calories per gram.

So how can this natural sweetener benefit your oral health? Take a look at the facts. Tooth decay starts when bacteria consumes the sugars left in your mouth. When you eat sugary foods, the bacteria on your teeth will multiply and make acid that can destroy your enamel.

Xylitol is derived from fibrous parts of plants, so it does not break down like a regular sugar. It actually helps maintain a neutral pH level in the mouth, which in turn prevents bacteria from sticking to the teeth. The bacteria are then unable to digest xylitol, which means your teeth won’t develop enamel damage and cavities.

Studies have shown the consumption of xylitol as a sugar substitute or a dietary addition had a dramatic reduction in new cavities and even reversed existing cavities. These effects are long lasting: low cavity rates remained years after the trials were done.

When there’s less bacteria and acid in your mouth due to xylitol, your teeth stay healthier. The more frequently it’s ingested, the more you will prevent enamel damage.

Aim to consume around five grams a day, or one gram every three hours if possible. You can do this by consuming gum, tablets, candy, or mints that have xylitol as one of the first ingredients after your meals. You can find these products in health food stores and specialty grocery stores.

Since xylitol replaces sugar on a one-to-one ratio, it’s used in several common items:

• Toothpaste
• Mouth rinse
• Baby oral wipes, gel, and pacifiers
• Nasal wash
• Dry mouth spray
• Granulated forms for cooking
• Granulated packets to add to drinks
• Commercially prepared foods

Make sure to pick up items that contain xylitol the next time you’re at the store! This is an easy way to maintain great oral health. If you have specific questions about xylitol, ask Dr. Keith J. Fabre Jr. during your next appointment at our Marrero office.

A dental emergency can strike anywhere, anytime, and without warning. Perhaps you’re playing a game of touch football on Thanksgiving and your brother-in-law decides to up the ante and tackles you, accidentally knocking out your two front teeth. Or maybe you’re on vacation somewhere in the tropics and decide to go deep-sea fishing, but when you’re climbing onto the boat you slip on the dock, fall, and chip three of your teeth. From misplaced fly balls to bagel seeds causing a painful bout of inflammation, there are all kinds of dental emergencies.

Here are the five most common reasons for emergency care visits.

1. Somehow you've managed to knock out a tooth. Whether it's the result of a sports injury or because of decay, when you lose a tooth, you need emergency dental care. If the tooth is salvageable, then it can be reattached to the socket, but this needs to be done within a one- or two-hour window.
2. A chipped tooth is the most common dental emergency. Small chips can be caused by food (chicken bones and nuts have sent many people to the dentist); however, it's usually some sort of accident or injury that more often causes a chip. While you might be embarrassed to walk around with a gaping chip in your front tooth, it is easily fixed with a bond, crown, or veneer.
3. A broken tooth is more severe than a chipped tooth. When a tooth breaks, it might be due to a small or hidden chip. However, chances are the pain and discomfort will be more severe.
4. It might seem comical, but getting a piece of food lodged in the wrong place can result in a dental emergency. If something gets stuck deep in a crevice, it can cause pain and inflammation.
5. The loss of a filling happens more often than you think. When you lose a filling, you need to receive emergency care immediately. If you don’t, you risk further damage to your tooth.

When you injure your teeth or mouth, you need to seek emergency care as soon as possible. In the event of a suspected emergency, don't wait. Contact Dr. Keith J. Fabre Jr. immediately.
