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.
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.
