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.

BoneLossattheRootscanPutYourToothinDangerofLoss

There’s more to teeth than meets the eye. Hidden beneath the visible crown are the tooth’s roots set within the jawbone, secured and protected by the gums from bacteria and infection. But if the gums shrink back (recede), the roots become exposed and susceptible to disease, especially at the points where multiple roots branch from each other, areas called furcations.

It all begins with periodontal (gum) disease caused by built-up bacterial plaque from insufficient brushing and flossing. The infection triggers inflammation that over time weakens gum tissues. They begin to detach from the teeth, which can eventually lead to gum recession and root exposure.

This also causes bone loss, especially at the furcations. We can detect any loss (known as a furcation invasion) and how far along it may be with x-ray imaging or by manually probing with an instrument called a periodontal probe.

There are three general classes measuring furcation invasions. In the earliest, Class I, we can feel the invasion as a slight groove; in Class II, it increases to two or more millimeters across. In Class III the bone loss extends from one side of the root all the way to the other (a “through and through”).

At this stage a patient is in danger of losing the tooth, so we’ll have to act promptly. This means first removing accumulated dental plaque and calculus (tartar) to stop the infection and allow the gums to heal. With severe damage, we may need to assist healing with bone and gum tissue grafting, in which we place donor grafts to serve as scaffolding for the appropriate tissue to grow upon.

You can help prevent this situation by practicing effective daily hygiene and visiting your dentist for thorough cleanings at least twice a year (or more if recommended). And at the first signs of a gum infection—swollen, reddened or bleeding gums—make an appointment as soon as possible to have it checked. The sooner we can detect and treat gum disease, the less likely a furcation invasion or worse will be in your future.

TomHanksAbscessedToothGetsCastAway

Did you see the move Cast Away starring Tom Hanks? If so, you probably remember the scene where Hanks, stranded on a remote island, knocks out his own abscessed tooth — with an ice skate, no less — to stop the pain. Recently, Dear Doctor TV interviewed Gary Archer, the dental technician who created that special effect and many others.

“They wanted to have an abscess above the tooth with all sorts of gunk and pus and stuff coming out of it,” Archer explained. “I met with Tom and I took impressions [of his mouth] and we came up with this wonderful little piece. It just slipped over his own natural teeth.” The actor could flick it out with his lower tooth when the time was right during the scene. It ended up looking so real that, as Archer said, “it was not for the easily squeamish!”

That’s for sure. But neither is a real abscess, which is an infection that becomes sealed off beneath the gum line. An abscess may result from a trapped piece of food, uncontrolled periodontal (gum) disease, or even an infection deep inside a tooth that has spread to adjacent periodontal tissues. In any case, the condition can cause intense pain due to the pressure that builds up in the pus-filled sac. Prompt treatment is required to relieve the pain, keep the infection from spreading to other areas of the face (or even elsewhere in the body), and prevent tooth loss.

Treatment involves draining the abscess, which usually stops the pain immediately, and then controlling the infection and removing its cause. This may require antibiotics and any of several in-office dental procedures, including gum surgery, a root canal, or a tooth extraction. But if you do have a tooth that can’t be saved, we promise we won’t remove it with an ice skate!

The best way to prevent an abscess from forming in the first place is to practice conscientious oral hygiene. By brushing your teeth twice each day for two minutes, and flossing at least once a day, you will go a long way towards keeping harmful oral bacteria from thriving in your mouth.
