Today’s crowns, the visible part of a tooth replacement system, can effectively mimic the shape and color of natural teeth. But not all crowns are equal — so it’s best to be well-informed before you undergo a restoration on your natural teeth such as a single crown or bridgework — or if you need a crown on a dental implant that replaces a missing tooth.
To give you a starting point, here are 3 things to keep in mind about crowns as you consider a dental restoration.
Material composition. Most crowns in years past were made of a precious metal, most notably gold. What it lacked in appearance, it made up for in performance and durability. In recent years, dental porcelain has become the popular choice because of its ability to mimic the appearance and translucent color of natural teeth. Today’s porcelains are much stronger and are used more frequently for back teeth than in years past. A common recommendation for back teeth is a hybrid crown using metal and porcelain. Metal is incorporated beneath the porcelain in this type of crown to create a strong foundation and is also used along biting surfaces for strength. Porcelain is used in the more visible areas for esthetics.
The dental technician’s level of artistry. Most dentists sub-contract crown fabrication to dental laboratory technicians who may have varying levels of experience and artistic ability. A highly skilled technician can produce a crown that blends seamlessly with the patient’s remaining natural teeth.
Take a “test drive” of your future smile. Although we as dentists adhere to certain aesthetic principles, beauty is ultimately subjective — “in the eye of the beholder.” The final product must meet your expectations and level of comfort. If available, then, consider wearing temporary “trial smile” crowns as a preview of your new smile while your permanent set is under construction. This allows you to “try out” your future smile ahead of time, so you can make recommendations and sign off on the final set before it’s finished.
Undertaking any dental restoration is an important life step, both for your health and appearance. Being well-informed — especially about the crowns that you and others will see — will help you make wise choices that lead to a satisfying outcome.
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.
