Our primary aim as dentists is to preserve teeth. There are times, however, when preserving a tooth is no longer worth the effort and we must recommend removing it. Fortunately, extracted teeth can be replaced with a functional and attractive restoration.
Today's top tooth-replacement option is the dental implant. Composed of a titanium metal post imbedded into the jawbone, a single dental implant can replace an individual tooth or a series of implants can support other restorations for multiple teeth. Besides being incredibly life-like, dental implants are highly durable and can last for decades.
But dental implants aren't an optimal choice for everyone. Their cost often matches their status as the premier tooth replacement method. And because they require a minimum amount of bone for proper implantation, they're not always feasible for patients with extensive bone loss.
But even if dental implants aren't right for you, and you want a fixed restoration rather than dentures, you still have options. What's more, they've been around for decades!
One is a bonded crown, which works particularly well for a tooth excessively damaged by decay, excessive wear or fractures. After removing all of the damaged portions and shaping the remaining tooth, we cement a life-like crown, custom created for that particular tooth, over the remaining structure.
Besides improving appearance, a crown also protects the tooth and restores its function. One thing to remember, though, is although the crown itself is impervious to disease, the remainder of the natural tooth isn't. It's important then to brush and floss around crowned teeth like any other tooth and see a dentist regularly for cleanings.
Dental bridges are a fixed solution for extracted teeth. It's composed of prosthetic teeth to replace those missing bonded together with supporting crowns on both ends. These crowned teeth are known as abutments, and, depending on how many teeth are being replaced, we may need to increase the number of abutments to support the bridge.
Although durable, crowns or bridges typically don't match the longevity of an implant. And, implants don't require the permanent alteration of support teeth as is necessary with a bridge. But when the choice of implants isn't on the table, these traditional restorations can be an effective dental solution.

For over three decades, Celine Dion has amazed audiences and fans with her powerful singing voice. Best known for her recording of "My Heart Will Go On," the theme song for the movie Titanic, Dion has amassed global record sales topping 200 million. In her early singing days, though, she struggled with one particular career obstacle: an unattractive smile.
The Canadian-born performer had a number of dental defects including crooked and discolored teeth, and—most prominent of all—abnormally large cuspid or "canine" teeth (located on either side of the four front incisors). They were so noticeable that one Quebec celebrity magazine gave her the unflattering nickname "Canine Dion."
This isn't an unusual problem. Since human canines are already the longest teeth in the mouth, it doesn't take much for them to stand out. Our ancient hunter-gatherer ancestors needed these large, pointed teeth to survive. But with the evolution of agriculture and industry, canine teeth have become gradually smaller—so much so that when they're abnormally large, they don't look right in a smile.
So, what can be done if your canines embarrassingly stand out from the rest? Here are some of the options to consider.
Reduce their size. If your canines are just a tad too long, it may be possible to remove some of the enamel layer in a procedure called contouring. Using this technique, we can reduce a tooth's overall size, which we then re-shape by bonding composite resin to the tooth. It's only a good option, though, if your canines have an ample and healthy layer of enamel.
Repair other teeth. The problem of prominent canine teeth may actually be caused by neighboring teeth. When the teeth next to the canines are crooked, the canines can appear more prominent. Alternatively, other teeth around the canines may be abnormally small. Braces or clear aligners can correct crooked incisors, and applying porcelain veneers to smaller teeth could help normalize their length.
Apply dental crowns. In some instances, we can reduce the canines in size and then bond porcelain crowns to them. This is the option that Dion ultimately chose. The natural teeth are still intact, but the crowning process transforms them into properly proportioned, life-like teeth. There is, however, one caveat: The alteration to these teeth will be permanent, so they will need a crown from then on.
Besides crowning her canine teeth, Dion also underwent other dental work to straighten and whiten her other teeth. As a result, this superstar performer now has a superstar smile to match and so can you if your teeth are less than perfect. These or other cosmetic enhancements can give you the look you truly desire. All it takes is an initial visit with us to start you on the road to a transformed smile.

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.
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.
