PreservingthePulpisPriorityOnewithaNewlyEruptedPermanentTooth

The change from primary teeth to permanent is an announcement to the world that a boy or girl is "growing up." "Growing up," though, is still not "grown"—the new teeth are still in a period of development that can affect how we treat them if they're injured or diseased.

While a new tooth erupts with all its anatomical layers, the middle dentin is somewhat thinner than it will be after it matures. The pulp, the tooth's innermost layer, produces new dentin and gradually increases the dentin layer during this early development period. While the pulp continues to produce dentin over a tooth's lifetime, most of it occurs in these early years.

To prevent or stop any infection, we would normally perform a root canal treatment in which we remove the pulp tissue and fill the empty pulp chamber and root canals. This poses no real issue in an older tooth with mature dentin. Removing the pulp from an immature tooth, though, could interrupt dentin development and interfere with the tooth's root growth. Besides a higher risk of discoloration, the tooth could become more brittle and prone to fracture.

That's why we place a high priority on preserving a younger tooth's pulp. Rather than a root canal treatment, we may treat it instead with one of a number of modified techniques that interact less with the pulp. Which of these we use will depend on the extent of the pulp's involvement with the injury or disease.

If it's unexposed, we may use a procedure called indirect pulp therapy, where we remove most of the tooth's damaged dentin but leave some of the harder portion intact next to the pulp to avoid exposure. If, though, some but not all of the pulp is damaged, we may perform a pulpotomy: here we remove the damaged pulp tissue while leaving the healthier portion intact. We may then apply a stimulant substance to encourage more dentin production to seal the exposure.

These and other techniques can help repair an injured young tooth while preserving most or all of its vital pulp. Although we can't always use them, when we can they could give the tooth its best chance for a full life.

KeepanEyeonYourFamilysFluorideIntake

Fluoride is a critical weapon in the war against tooth decay. But this natural chemical proven to strengthen tooth enamel has also aroused suspicion over the years that it might cause health problems.

These suspicions have led to rigorous testing of fluoride's safety. And the verdict from decades of research? We've found only one verifiable side effect, a condition called enamel fluorosis. Caused by too much fluoride present in the body, enamel fluorosis produces white streaks and patches on teeth, and can develop into darker staining and pitting in extreme cases. But other than having an unattractive appearance, the teeth remain sound and healthy.

Fortunately, you can reduce the risk of fluorosis by limiting fluoride exposure to within recommended limits. Fluoride can show up in processed foods and other substances, but the two sources you should focus on most are oral hygiene products and fluoridated drinking water.

Dentists highly recommend using toothpaste with fluoride to fight tooth decay. But be careful how much your family uses, especially younger members. An infant only needs a slight smear of toothpaste on their brush for effective hygiene. At around age 2, you can increase the amount to about the size of a vegetable pea.

As to drinking water, most utilities add fluoride to their supply. If yours does, you can find out how much they add by calling them or visiting cdc.gov ("My Water's Fluoride"), where you can also learn more about recommended levels of fluoridation. If you think it's excessive, you can switch to water labeled "de-ionized," "purified," "demineralized," or "distilled," which contain little to no added fluoride.

Even if your fluoridated water is within recommended levels, you may wish to take extra precautions for infants nursing with formula. If possible, use "ready-to-feed" formula, which usually contains very low amounts of fluoride if any. If you're using the powdered form, use only water with the aforementioned labeling for mixing.

Before making any drastic changes that might affect your family's fluoride intake, consult with your dentist first. And be sure you're keeping up regular dental visits—your dentist may be able to detect any early signs of fluorosis before it becomes a bigger problem.

TransformingYourSmilewithVeneersStepbyStep

Dental veneers are a great way to transform a smile without the expense or effort often required of other restorations. These thin layers of dental material adhere to the front of teeth as a "mask" to cover chips, heavy staining or other blemishes.

Still, veneers require attention to detail for a successful outcome. Here's a step-by-step look at changing your dental appearance with veneers.

Step 1: Considering your options. While most veneers are made of dental porcelain, composite resin materials are increasingly popular. Although more prone to chipping or staining, composite veneers don't require a dental lab for fabrication. Another option, depending on your dental situation, are ultra-thin veneers that require little to no tooth preparation. Your dentist will help you decide which options are best for you.

Step 2: "Test driving" your new smile. We can help you "see" your future smile with special software that creates a computer image of your teeth with the planned veneers. We can also use composite material to fabricate a "trial smile" to temporarily place on your teeth that can give you the feel as well as the look of your future smile.

Step 3: Preparing your teeth. Unless you're getting no-prep veneers, we'll need to modify your teeth before attaching veneers. Although only 0.3 to 0.7 millimeters thick, veneers can still appear bulky on unprepared teeth. They'll look more natural if we first remove a small amount of enamel. A word of caution, though: although slight, this enamel removal permanently alters your teeth that will require them to have some form of restoration from then on.

Step 4: Attaching your new veneers. After the planning phase (which includes color matching to blend the veneers with the rest of your teeth), a dental lab creates your veneers if you've opted for porcelain. After they're delivered, we'll clean and etch the teeth with a mild acidic gel to increase the bonding effect. We'll then permanently attach the veneers to your teeth with a very thin but ultra-strong resin luting cement that creates a unified bond between the veneers and teeth.

Following these steps is the surest way to achieve a successful outcome. With due care you're sure to enjoy the effects for a long time to come.

ActorDavidRamseySaysDontForgettoFloss

Can you have healthy teeth and still have gum disease? Absolutely! And if you don’t believe us, just ask actor David Ramsey. The cast member of TV hits such as Dexter and Arrow said in a recent interview that up to the present day, he has never had a single cavity. Yet at a routine dental visit during his college years, Ramsey’s dentist pointed out how easily his gums bled during the exam. This was an early sign of periodontal (gum) disease, the dentist told him.

“I learned that just because you don’t have cavities, doesn’t mean you don’t have periodontal disease,” Ramsey said.

Apparently, Ramsey had always been very conscientious about brushing his teeth but he never flossed them.

“This isn’t just some strange phenomenon that exists just in my house — a lot of people who brush don’t really floss,” he noted.

Unfortunately, that’s true — and we’d certainly like to change it. So why is flossing so important?

Oral diseases such as tooth decay and periodontal disease often start when dental plaque, a bacteria-laden film that collects on teeth, is allowed to build up. These sticky deposits can harden into a substance called tartar or calculus, which is irritating to the gums and must be removed during a professional teeth cleaning.

Brushing teeth is one way to remove soft plaque, but it is not effective at reaching bacteria or food debris between teeth. That’s where flossing comes in. Floss can fit into spaces that your toothbrush never reaches. In fact, if you don’t floss, you’re leaving about a third to half of your tooth surfaces unclean — and, as David Ramsey found out, that’s a path to periodontal disease.

Since then, however, Ramsey has become a meticulous flosser, and he proudly notes that the long-ago dental appointment “was the last we heard of any type of gum disease.”

Let that be the same for you! Just remember to brush and floss, eat a good diet low in sugar, and come in to the dental office for regular professional cleanings.

If you would like more information on flossing or periodontal disease, please contact us today to schedule an appointment for a consultation. You can also learn more by reading the Dear Doctor magazine article “Understanding Gum (Periodontal) Disease.”

YourSinusInfectionMightbeaSignofaToothProblem

Each year thousands of people develop sinus infections from various causes. But there's one cause for sinusitis that might surprise you—tooth decay.

Tooth decay begins when the acid produced by oral bacteria erodes a tooth's enamel protection to create a small hole or cavity. Left untreated, the infection can move into the inner pulp of the tooth and tiny passageways leading to the roots called root canals. The decay can then infect and break down the structure of the supporting jawbone.

This could affect the sinus cavities, hollow air-filled spaces in the upper portion of the face. The maxillary sinus in particular sits behind the cheek bones just above the upper jaw. Tooth roots, particularly in back teeth, can extend quite near or even poke through the floor of the maxillary sinus.

If decay affects these roots, the bone beneath this floor may begin to break down and allow the bacterial infection to enter the sinus. We call this particular kind of sinus infection maxillary sinusitis of endodontic origin (MSEO), "endodontic" referring to the interior structure of teeth.

While advanced decay can show symptoms like pain or sensitivity with certain hot or cold foods, it's also possible to have it and not know it directly. But a recurring sinus infection could be an indirect indication that the root of your suffering is a deeply decayed tooth. Treating the sinus infection with antibiotics won't cure this underlying dental problem. For that you'll need to see a dentist or an endodontist, a specialist for interior tooth issues.

The most common way to treat deep tooth decay is with root canal therapy. In this procedure, the dentist enters the decayed tooth's pulp (nerve chamber) and root canals and removes the diseased tissue. They will then fill the empty pulp and root canals with a special filling and seal the tooth to prevent future infection. The procedure stops the infection and saves the tooth—and if you have MSEO, it eliminates the cause of the sinus infection.

So, if you're suffering from chronic sinus infections, you might talk with your dentist about the possibility of a tooth infection. A thorough examination might reveal a decayed tooth in need of treatment.
