So, you're about to have a tooth capped with a crown. Do you know what you need to know before you undergo this common dental procedure?
Here's a short true or false quiz to test your knowledge of dental crowns.
All crowns are the same. False — while all crowns have the same basic design — a life-like prosthetic tooth fitted over and bonded or cemented to a natural tooth — their compositions can vary greatly. Early metal crowns consisted mainly of gold or silver and are still used today. Porcelain-fused-to-metal (PFM) crowns — a metal interior for strength overlaid by a porcelain exterior for appearance — became popular in the latter 20th Century. Although still widely used, PFMs have been largely surpassed by newer all-ceramic materials that are stronger than past versions.
Crowns can differ in their artistic quality. True — all crowns are designed to replicate a natural tooth's function — in other words, enable the tooth to effectively chew again. But a crown's appearance can be a different story, depending on how much attention to detail and artistry goes into it. The higher the individual craftsmanship, the more lifelike it will appear — and the more expensive it can be.
With digital milling equipment, dental labs are obsolete. False — although technology exists that allows dentists to produce their own crowns, the equipment is not yet in widespread use. Â The vast majority of crowns are still produced by a trained technician in a dental laboratory. And just as you base your choice of a dentist on your confidence in and respect for them, dentists look for the same thing in a dental lab — good, reliable and consistent results.
Your insurance may not cover what your dentist recommends. True — dental insurance will typically pay for a basic, functional crown. Aesthetics — how it will look — is a secondary consideration. As a result, your policy may not cover the crown your dentist recommends to function properly and look attractive. A new crown, however, is a long-term investment in both your dental function and your smile. It may be well worth supplementing out of pocket your insurance benefit to get the crown that suits you on both counts.
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.
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.
