ToothTypeandConditioncanAffectRootCanalTherapyEffectiveness

Root canal therapy is the unsung "hero" of dentistry. Although often falsely maligned as an unpleasant experience, millions of decayed teeth have been saved thanks to this routine treatment.

But although root canal therapy can save your tooth, we can't guarantee it won't be affected by another infection. There are other factors to consider how long a treated tooth will remain healthy.

Root canal therapy stops and limits the damage from tooth decay that has infected the inner pulp and root canals. A dentist or endodontist (a root canal specialist) drills into the tooth to gain access to the pulp. They remove the diseased pulp tissue and then fill the empty pulp chamber and root canals with a specialized filling called gutta percha. The tooth is then sealed and later crowned to protect it against future fracture or infection.

The probability of that occurring may depend on when a dentist performs the root canal in the disease progression—and the earlier the better. If decay has already infected the underlying bone, the tooth's long-term prognosis even with root canal therapy could be dim. That's why you should see a dentist as soon as possible for any tooth pain, even if it goes away.

The type of tooth could impact long-term health. Teeth with single roots are usually easier to treat. But those with multiple roots and an intricate root canal network can be more difficult to treat, and require specialized equipment and techniques.

Age can also impact root canal therapy longevity. The older a root canal-treated tooth is, the more brittle and susceptible to fracture it can become, which can pose complications. That's why we typically place crowns on treated teeth to protect them from both future infection and undue stress created while biting and chewing.

To help mitigate these possible factors, you should see your dentist regularly for checkups and at the first sign of pain or other abnormalities for the earliest treatment possible. And for more complex tooth issues, your dentist may refer you to an endodontist to perform your root canal. With early intervention and attentive care, your root canaled tooth could enjoy many years of life.

DoThisforYourDentalHealthBeforeDuringandAfterCancerTreatment

Although cancer treatment has advanced steadily in recent decades, the most used therapies continue to be radiation and chemotherapy to eradicate cancerous cells. And while they often work, both can cause "collateral damage" in healthy tissues near the targeted cells.

This can create a number of indirect consequences for a patient's health, including in the mouth. The salivary glands, for example, can be damaged by radiation treatments aimed at the head or neck. The effect on these glands can interrupt the normal flow of saliva and cause xerostomia or "dry mouth."

Lack of adequate saliva causes more than an unpleasant, sticky mouth feeling. One of saliva's main functions is to neutralize acid that builds up naturally after eating. Without it, high acid levels can cause enamel and root surface erosion and lead to tooth decay.

Cancer treatment can also contribute to gastro-esophageal reflux disease (GERD). This disease causes stomach acid to bypass the natural tissue barriers of the esophagus and enter the mouth. As with dry mouth, the increased acid level from GERD can be just as devastating to enamel—and the damage will be permanent.

To minimize these effects on your dental health, it's important to take proactive steps before, during and after cancer treatment. If at all possible, have any needed dental work performed before you begin radiation or chemotherapy—it's better to start it with teeth and gums as healthy as possible.

During treatment, try to continue regular dental visits to monitor your oral health and receive any needed preventive or therapeutic treatments. Depending on your condition and the advice of your dentist, you may need to increase your visit frequency during this time. Your dentist can help with boosting your saliva production and strengthening your tooth enamel. But you should also practice daily brushing and flossing, drink plenty of water and seek treatment for any resulting GERD symptoms.

Even with the best efforts, though, your teeth and gums may still incur damage while treating your cancer. Fortunately, there are a wide array of materials and procedures that can effectively restore them to health. So, once your treatments are completed consult with a dentist on your options for improving the health and appearance of your teeth and gums.

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.

DentalCrownsfortheKingofMagic

You might think David Copperfield leads a charmed life:  He can escape from ropes, chains, and prison cells, make a Learjet or a railroad car disappear, and even appear to fly above the stage. But the illustrious illusionist will be the first to admit that making all that magic takes a lot of hard work. And he recently told Dear Doctor magazine that his brilliant smile has benefitted from plenty of behind-the-scenes dental work as well.

“When I was a kid, I had every kind of [treatment]. I had braces, I had headgear, I had rubber bands, and a retainer afterward,” Copperfield said. And then, just when his orthodontic treatment was finally complete, disaster struck. “I was at a mall, running down this concrete alleyway, and there was a little ledge… and I went BOOM!”

Copperfield’s two front teeth were badly injured by the impact. “My front teeth became nice little points,” he said. Yet, although they had lost a great deal of their structure, his dentist was able to restore those damaged teeth in a very natural-looking way. What kind of “magic” did the dentist use?

In Copperfield’s case, the teeth were repaired using crown restorations. Crowns (also called caps) are suitable when a tooth has lost part of its visible structure, but still has healthy roots beneath the gum line. To perform a crown restoration, the first step is to make a precise model of your teeth, often called an impression. This allows a replacement for the visible part of the tooth to be fabricated, and ensures it will fit precisely into your smile. In its exact shape and shade, a well-made crown matches your natural teeth so well that it’s virtually impossible to tell them apart. Subsequently, the crown restoration is permanently attached to the damaged tooth.

There’s a blend of technology and art in making high quality crowns — just as there is in some stage-crafted illusions. But the difference is that the replacement tooth is not just an illusion: It looks, functions and “feels” like your natural teeth… and with proper care it can last for many years to come.  Besides crowns, there are several other types of tooth restorations that are suitable in different situations. We can recommend the right kind of “magic” for you.

ADetailedSmileAnalysisSetstheStageforaSuccessfulMakeover

Cosmetic dentists routinely perform smile transformations once thought impossible. Using the latest materials and techniques, today's practitioners can "make over" the most problematic smiles.

But to achieve these results, it's necessary for both dentist and patient to step back and absorb the "bigger picture." If you're considering a smile makeover, your first step on this transformative journey will be this big picture moment called a smile analysis.

A smile analysis is a comprehensive examination in which your dentist looks at every aspect of your current smile. And not just your teeth and gums—he or she will also carefully evaluate the health of the supporting bone of the jaw. Healthy bone is necessary in particular for dental implants, which require adequate bone for optimum placement. Extensive bone loss could rule out implants, or at least postpone their installation until the bone can be rejuvenated through bone grafting.

The analysis doesn't stop with mouth structures, either: an attractive smile must achieve an aesthetic balance with the shape and complexion of the face, especially the color and position of the eyes and the form and posture of the lips. Your dentist will measure and assess all of these facial features and factor them into your individual smile makeover plan. This increases the likelihood your planned restorations will blend seamlessly with your overall appearance.

Your smile analysis will also include what's going on beneath the surface of your current smile. Many appearance problems are actually the consequences of disease, trauma or inherited conditions. These underlying issues will often need to be addressed first: as with renovating a house, it does little good to paint and hang wall paper if the foundation is faulty. Any treatment for disease or trauma may postpone cosmetic work, but it's absolutely necessary to achieve lasting success for your smile makeover.

Although time-consuming, a smile analysis sets the stage for a successful smile transformation. Your new beautiful smile will be well worth this detailed examination.
