WhatChrissyTeigensInaugurationNightCapMishapCouldMeanForYou

Inauguration night is usually a lavish, Washington, D.C., affair with hundreds attending inaugural balls throughout the city. And when you're an A-List celebrity whose husband is a headliner at one of the events, it's sure to be a memorable night. As it was for super model Chrissy Teigen—but for a slightly different reason. During the festivities in January, Teigen lost a tooth.

Actually, it was a crown, but once she told a Twitter follower that she loved it “like he was a real tooth.” The incident happened while she was snacking on a Fruit Roll-Up (those sticky devils!), and for a while there, husband and performer John Legend had to yield center stage to the forlorn cap.

But here's something to consider: If not for the roll-up (and Teigen's tweets on the accident) all of us except Teigen, her dentist and her inner circle, would never have known she had a capped tooth. That's because today's porcelain crowns are altogether life-like. You don't have to sacrifice appearance to protect a tooth, especially one that's visible when you smile (in the “Smile Zone”).

It wasn't always like that. Although there have been tooth-colored materials for decades, they weren't as durable as the crown of choice for most of the 20th Century, one made of metal. But while gold or silver crowns held up well against the daily grind of biting forces, their metallic appearance was anything but tooth-like.

Later, dentists developed a hybrid of sorts—a metal crown fused within a tooth-colored porcelain shell. These PFM (porcelain-fused-to-metal) crowns offered both strength and a life-like appearance. They were so effective on both counts that PFMs were the most widely used crowns by dentists until the early 2000s.

But PFMs today make up only 40% of currently placed crowns, down from a high of 83% in 2005. What dethroned them? The all-ceramic porcelain crown—but composed of different materials from years past. Today's all-ceramic crowns are made of more durable materials like lithium disilicate or zirconium oxide (the strongest known porcelain) that make them nearly as strong as metal or PFM crowns.

What's more, coupled with advanced techniques to produce them, all-ceramic crowns are incredibly life-like. You may still need a traditional crown on a back tooth where biting forces are much higher and visibility isn't an issue. But for a tooth in the “Smile Zone”, an all-ceramic crown is more than suitable.

If you need a new crown (hopefully not by way of a sticky snack) or you want to upgrade your existing dental work, see us for a complete exam. A modern all-ceramic crown can protect your tooth and enhance your smile.

3ThingsYouNeedtoKnowBeforeGettingaCrownRestoration

You may think all crowns are alike—but there can be a world of difference between one crown and another. Getting the crown your dentist recommends and one that's satisfactory to you will depend on a number of factors, including what you'll ultimately have to pay.

Here are 3 things you need to know about crowns before undergoing a crown restoration.

Different materials. Although porcelain is the most life-like material used, earlier types of this glass-based material weren't strong enough to withstand biting forces, especially in back teeth. Years ago, all-metal crowns were most often used until the development of a hybrid porcelain crown with an inner metal substructure for strength. In recent years stronger all-porcelain crowns have risen in popularity. The material type that works best often depends on the tooth to be crowned—all-porcelain may work for a visible front incisor, but a porcelain-metal hybrid might be needed for a back molar.

Level of artistry. While new computer manufacturing systems allow dentists to produce patient crowns in-office, most still require the services and skills of a dental lab technician. The cost difference between crowns usually occurs at this juncture: the more life-like and customized the crown, the more artistry and time required by a technician to produce it. This can increase the cost of the crown.

Limited choices. While you and your dentist want your crown choice to be as individualized and life-like as possible, your dental insurance may limit your options. Many policies only provide benefits for the most basic crown restoration—enough to regain functionality and have an acceptable, but not always the most aesthetic, appearance. To get a higher quality of crown you may have to supplement what your policy and deductible will cover.

Deciding which crown is best will depend on where it will be needed, the level of attractiveness you desire and your insurance and financial comfort level. And your dentist can certainly help guide you to a crown choice that's right for you.
