AreYouintheKnowAboutDentalCrownsTakeourTrueorFalseQuiz

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.  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.

ACrownCouldbetheAnswertoPreservingYourDamagedTooth

We’ve been treating one of your decay-prone teeth for some time with one filling after another. Each incident required a little more removal of decayed tooth material until now there isn’t enough structure to support another filling.

We could remove the tooth and replace it with a bridge or a dental implant, both viable restoration options. But keeping the tooth if possible would be more beneficial in the long-run for your gums, bone and remaining teeth. If it still has a healthy and stable root, it’s possible to permanently cover or “cap” the tooth with a life-like crown.

Crowns have been used for decades: the first were mainly composed of metal like gold or silver and later dental porcelain, a ceramic material that could be molded, shaped and oven-fired to resemble a real tooth. The earliest porcelains, though, were brittle, so a hybrid with a metal interior for strength and a fused exterior porcelain layer for appearance came into prominence.

Today, advances in materials have led to all-porcelain crowns strong enough to withstand biting forces. While the metal-porcelain hybrid still account for about 40% of crowns installed annually, the all-porcelain types are steadily growing in popularity.

Regardless of the type, though, the process for fitting any crown is relatively the same. The first step is to reshape the affected tooth so that the future crown will fit over it, followed by an impression mold of the tooth a dental technician will use to form a custom crown. Once the new crown has been prepared, we then permanently bond it to the tooth.

With a crown, you’ll be able to enjoy normal function and have a tooth that looks as healthy and normal as its neighbors. Be aware, though, that your underlying tooth is still subject to decay — so diligent, daily hygiene and regular dental visits are a must. With proper care your newly crowned tooth can continue to serve you and your smile for many years to come.
