Learn about crowns and bridges from your Chicago Loop dentist.
A Gallup poll found that up to a third of Americans didn’t visit the dentist’s office in the course of a year. Unfortunately, the longer you avoid going to the dentist’s office, the higher the chance of dental problems that may require restorative work. If you’ve been looking for a restorative solution for your smile, crowns or bridges may be your best option. Learn more about these common dental treatments by exploring a few frequently asked questions.
What Is the Difference Between Crowns and Bridges?
A crown is a whole covering, commonly made of porcelain, metal or ceramic material, that replaces the enamel layer of the tooth. It is bonded on top of a healthy rooted tooth that needs strengthening and protection. A bridge is a device that uses two crowns to fill in a gap in the smile from a missing tooth. The crowns cover the two adjacent teeth, called abutments. The center of the bridge called a pontic, is a false tooth that is designed to fit in with the rest of your smile.
Who Is a Good Candidate for Crowns?
Since a crown is only a superficial covering, the inner parts of the tooth have to be healthy to support it. A dentist must examine the inside of the tooth using X-rays to confirm that the tooth is healthy enough for a crown. Patients who have root canal therapy are also candidates for crowns.
Who Needs Bridges?
Someone who has one or two missing teeth and wants a reasonably secure and semi-permanent solution may benefit from bridges. The bridge is needed to help make it easier to process food, maintain the structure of the jawline and give the patient a smile to be proud of. The abutment teeth have to be healthy enough to support a crown. Generally, a good candidate for a crown will likely also be a good candidate for bridgework.
How Long Will These Dental Solutions Last?
A crown or bridge can last for between five to 15 years or even longer if you take care of your teeth. But no worries, because when the time comes your dentist can redo the crown or bridge and give you another 15 or more years to enjoy your new smile.

Want to know the exact wrong way to pry open a stubborn lid? Just ask Jimmy Fallon, host of NBC-TV’s popular “Tonight Show.” When the 40-year-old funnyman had trouble opening a tube of scar tissue repair gel with his hands, he decided to try using his teeth.
What happened next wasn’t funny: Attempting to remove the cap, Fallon chipped his front tooth, adding another medical problem to the serious finger injury he suffered a few weeks before (the same wound he was trying to take care of with the gel). If there’s a moral to this story, it might be this: Use the right tool for the job… and that tool isn’t your teeth!
Yet Fallon is hardly alone in his dilemma. According to the American Association of Endodontists, chipped teeth account for the majority of dental injuries. Fortunately, modern dentistry offers a number of great ways to restore damaged teeth.
If the chip is relatively small, it’s often possible to fix it with cosmetic bonding. In this procedure, tough, natural-looking resin is used to fill in the part of the tooth that has been lost. Built up layer by layer, the composite resin is cured with a special light until it’s hard, shiny… and difficult to tell from your natural teeth. Best of all, cosmetic bonding can often be done in one office visit, with little or no discomfort. It can last for up to ten years, so it’s great for kids who may be getting more permanent repairs later.
For larger chips or cracks, veneers or crowns may be suggested. Veneers are wafer-thin porcelain coverings that go over the entire front surface of one or more teeth. They can be used to repair minor to moderate defects, such as chips, discolorations, or spacing irregularities. They can also give you the “Hollywood white” smile you’ve seen on many celebrities.
Veneers are generally custom-made in a lab, and require more than one office visit. Because a small amount of tooth structure must be removed in order to put them in place, veneers are considered an irreversible treatment. But durable and long-lasting veneers are the restorations of choice for many people.
Crowns (also called caps) are used when even more of the tooth structure is missing. They can replace the entire visible part of the tooth, as long as the tooth’s roots remain viable. Crowns, like veneers, are custom-fabricated to match your teeth in size, shape and color; they are generally made in a dental lab and require more than one office visit. However, teeth restored with crowns function well, look natural, and can last for many years.
So what happened to Jimmy Fallon? We aren’t sure which restoration he received… but we do know that he was back on TV the same night, flashing a big smile.

You might think David Copperfield leads a charmed life:Â 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.Â 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.

The traditional way to restore a tooth with an artificial crown takes several weeks and multiple office visits: from tooth preparation and impression molding to crown production by a dental laboratory, followed by adjustments and cementing. Now, there’s an alternative that reduces this process to a fraction of the time, and all from your dentist’s office.
Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) is a digital system that enables dentists to create dental restorations with laboratory-grade materials in minutes rather than weeks. As it continues to innovate, you’ll see more and more dentists investing in the new technology for their patients.
A crown restoration with CAD/CAM begins like any other with decay removal and preparation of the tooth. It diverges, though, from the traditional in how an impression of your teeth and gums is obtained: instead of rubber-like molding materials to create a physical impression, we lightly dust the mouth interior with a reflective powder. Using a scanning wand, the reflective powder allows us to capture multiple, detailed images of your mouth that the CAD/CAM computer transforms into an accurate three-dimensional model.
We use the model to first assess if the tooth has been effectively prepared for a restoration. If so, the design feature of the system will provide us with thousands of tooth forms to choose from to match with your natural teeth. You’ll be able to view the proposed size and shape of the new crown via computer simulation before signing off on the design.
Next is the actual manufacture of the crown that takes place right in the dentist’s office. A pre-formed block of ceramic material is inserted in the milling equipment where, following the pre-determined computer design, the milling heads carve the ceramic block. After milling, we fine-tune the crown surface and apply stains or glazes fired to create a life-like color and texture that matches your natural teeth. We can then adjust the crown in your mouth and permanently affix it to the tooth.
While much of the CAD/CAM system is automated, ultimate success still depends on the dentist’s expertise and artistry. CAD/CAM enhances those skills with greater precision and in much less time than traditional crowns. It’s certainly a growing option for many people to restore the form and function of decayed teeth.

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.
