NotallDentalCrownsSharetheSameQualityofLife-Likeness

Dental crowns are an essential means for restoring damaged or unattractive teeth. A well-crafted crown not only functions well, it looks and blends seamlessly with the rest of the natural teeth.

Crowns are artificial caps that cover an entire visible tooth, often used for heavily decayed or damaged teeth or as added protection after a root canal treatment. Most crowns are produced by a dental lab, but some dentists are now creating them in-office with computer-based milling equipment. On the whole, the various crowns now available function adequately as teeth—but they can vary in their appearance quality.

In the early to mid 20th Century the all-metal crown was the standard; but while durable, it could be less than eye-pleasing. Although more life-like dental porcelain existed at the time, it tended to be brittle and could easily shatter under chewing stress.

Dentists then developed a crown that combined the strength of metal with the attractiveness of porcelain: the porcelain fused to metal or PFM crown. The PFM crown had a hollow, metal substructure that was cemented over the tooth. To this metal base was fused an outer shell of porcelain that gave the crown an attractive finish.

The PFM reigned as the most widely used crown until the mid 2000s. By then improved forms of porcelain reinforced with stronger materials like Lucite had made possible an all-ceramic crown. They’re now the most common crown used today, beautifully life-like yet durable without the need for a metal base.

All-ceramics may be the most common type of crown installed today, but past favorites’ metal and PFM are still available and sometimes used. So depending on the type and location of the tooth and your own expectations, there’s a right crown for you.

However, not all crowns even among all-ceramic have the same level of aesthetic quality or cost—the more life-like, the more expensive. If you have dental insurance, your plan’s benefits might be based on a utilitarian but less attractive crown. You may have to pay more out of pocket for the crown you and your dentist believe is best for you.

Whatever you choose, though, your modern dental crown will do an admirable, functional job. And it can certainly improve your natural tooth’s appearance.

RoyalTreatmentforaDamagedTooth

If your tooth sustains damage that compromises its structure — typically through decay or trauma — you have several options depending on the extent of the damage: One of them is a crown. This method saves the tooth and its root and completely conceals the visible portion of the tooth, or crown, under a natural-looking cap made to mimic as closely as possible the size, shape and color of the original tooth.

Crowns also hide imperfections in the original tooth like discoloration, chipping, fractures, excessive wear (from bruxism, or tooth grinding, for example), or abnormalities in the way the tooth formed. And they’re used following root canal treatments, which treat infected pulp at the center (canal) of a tooth root by removing the pulp and replacing it with an inert, rubber-like material.

Saving the natural tooth has long been the goal of dentistry because normal micromovements of the tooth root, which is suspended in its jawbone socket by elastic ligaments, stimulate the surrounding bone to rejuvenate. Without that stimulation, the bone continues to lose old cells, but no longer replaces them. Crowns are also designed to restore tooth function.

The function and location of the damaged tooth can determine what material the crown will be made of. If the damaged tooth is clearly visible when you smile, porcelain, the most realistic-looking material, is almost always used. If the tooth receives significant bite force, a stronger material is considered — either, a gold/porcelain combination, or a high-strength ceramic. If you are restoring a second molar, an all-gold crown may be considered.

With the advent of dental implants, saving a damaged tooth is no longer the only option for preserving the health of the bone surrounding the tooth root. The implant — a tiny biocompatible, titanium screw-like artificial root — is placed in the jawbone and is then capped with a natural-looking crown of course!

CustomizedTemporaryCrownsHelpEnsureaSatisfyingPermanentSmile

Restoring missing or unattractive teeth can often be a lengthy process. Months may elapse between initial teeth preparation and final placement to allow time for tissue healing and permanent crown manufacturing. During that period you will likely wear temporary (provisional) crowns to protect the teeth while improving function and appearance.

In the past, provisional crowns were fairly uniform. Today, though, there are provisional crowns available that conform exactly to a patient’s individual mouth. These crowns not only enhance function and appearance, they’re an excellent way to “try out” your new smile before the permanent restoration.

Customized provisional crowns are part of a concept known as “smile analysis.” A new smile involves more than restoring affected teeth: we also consider the overall health of your mouth, the shape of your face, and your own desires and expectations. Your final smile design is a joint collaboration between you, our office and the dental laboratory that will fashion the final restoration.

There are a number of techniques for creating customized provisional crowns. Some techniques involve bonding tooth-colored materials like composite resin directly to the teeth. Others use impression models of your teeth to create an outline or shell that’s filled with an acrylic material and then affixed to your teeth. The aim with any of these techniques is to produce a provisional crown that accurately reflects the final crown’s appearance.

With these types of provisional crowns, we can see how the new teeth will look (their color, shading, shapes and proportions) against the gums, and if they appear to be in balance and harmony with the entire face, including your lips, jaws and facial contour. We can also evaluate how well the new teeth function as you chew, speak or smile.

It takes some extra effort to prepare customized provisional crowns rather than the more uniform version. But this effort is well worth it: by helping us anticipate more accurately how your new restorations will appear and function, customized crowns help ensure your new smile is an attractive and satisfying one.

AToothlessTiger

Let’s say you’re traveling to Italy to surprise your girlfriend, who is competing in an alpine ski race… and when you lower the scarf that’s covering your face, you reveal to the assembled paparazzi that one of your front teeth is missing. What will you do about this dental dilemma?

Sound far-fetched? It recently happened to one of the most recognized figures in sports — Tiger Woods. There’s still some uncertainty about exactly how this tooth was taken out: Was it a collision with a cameraman, as Woods’ agent reported… or did Woods already have some problems with the tooth, as others have speculated? We still don’t know for sure, but the big question is: What happens next?

Fortunately, contemporary dentistry offers several good solutions for the problem of missing teeth. Which one is best? It depends on each individual’s particular situation.

Let’s say that the visible part of the tooth (the crown) has been damaged by a dental trauma (such as a collision or a blow to the face), but the tooth still has healthy roots. In this case, it’s often possible to keep the roots and replace the tooth above the gum line with a crown restoration (also called a cap). Crowns are generally made to order in a dental lab, and are placed on a prepared tooth in a procedure that requires two office visits: one to prepare the tooth for restoration and to make a model of the mouth and the second to place the custom-manufactured crown and complete the restoration. However, in some cases, crowns can be made on special machinery right in the dental office, and placed during the same visit.

But what happens if the root isn’t viable — for example, if the tooth is deeply fractured, or completely knocked out and unable to be successfully re-implanted?

In that case, a dental implant is probably the best option for tooth replacement. An implant consists of a screw-like post of titanium metal that is inserted into the jawbone during a minor surgical procedure. Titanium has a unique property: It can fuse with living bone tissue, allowing it to act as a secure anchor for the replacement tooth system. The crown of the implant is similar to the one mentioned above, except that it’s made to attach to the titanium implant instead of the natural tooth.

Dental implants look, function and “feel” just like natural teeth — and with proper care, they can last a lifetime. Although they may be initially expensive, their quality and longevity makes them a good value over the long term. A less-costly alternative is traditional bridgework — but this method requires some dental work on the adjacent, healthy teeth; plus, it isn’t expected to last as long as an implant, and it may make the teeth more prone to problems down the road.

What will the acclaimed golfer do? No doubt Tiger’s dentist will help him make the right tooth-replacement decision.

If you have a gap in your grin — whatever the cause — contact us or schedule an appointment for a consultation, and find out which tooth-replacement system is right for you. You can learn more in the Dear Doctor magazine articles “Dental Implant Surgery” and “Crowns & Bridgework.”

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.
