CrownDifferencesCouldUltimatelyAffectYourCost

Crowns are a mainstay of cosmetic dentistry used to improve your smile’s appearance in a variety of situations. Not all crowns are alike, though — and the differences could affect your cost.

Crowns or caps are needed to cover remaining tooth structure which was previously damaged. Tooth decay and trauma are the major reasons for damage or loss of tooth structure that make crowns necessary. After preparing the remaining healthy tooth to fit into the new crown, we then make an impression mold of the tooth for a dental technician to use to create the new crown. It’s at this point where the road to your new smile can take different paths, both in construction and how much artistry goes in to your crown’s formation.

Porcelain crown construction falls into two general categories. The first category involves life-like porcelain fused to an inner core of metal. Because many older types of porcelain tend to be brittle and subject to breaking under pressure, metals are used to strengthen the crown. A fused crown can thus provide both durability and a life-like appearance.

In recent years, though, new dental materials have made the second category — all porcelain crowns — a viable option. Either lithium disilicate or zirconium oxide account for nearly two-thirds of crowns made today. Although research on their durability is relatively new, initial results have been encouraging, showing advanced all-ceramic crowns can tolerate forces comparable to porcelain fused to metal (PFM) crowns used in bridges.

On the downside, these newer materials may be more expensive than PFM crowns. Costs for manufacturing may also increase depending on how life-like the matching of color with other teeth you desire your crown to be. For example, individual teeth aren’t a uniform color — there are gradations of color that can vary from the tip of the tooth to the root. To capture these gradations in an individual crown requires a high level of artistry and time by the dental technician, which increases the final cost.

If you’re in need of a crown, it’s best to first make an appointment for a consultation to review your options, and to consider both your expectations and financial ability. Together we can determine what it will take to create a new look for your teeth that fits your expectations and your budget.

HowKathyBatesRetainsHerMovie-StarSmile

In her decades-long career, renowned actress Kathy Bates has won Golden Globes, Emmys, and many other honors. Bates began acting in her twenties, but didn't achieve national recognition until she won the best actress Oscar for Misery — when she was 42 years old! “I was told early on that because of my physique and my look, I'd probably blossom more in my middle age,” she recently told Dear Doctor magazine. “[That] has certainly been true.” So if there's one lesson we can take from her success, it might be that persistence pays off.

When it comes to her smile, Kathy also recognizes the value of persistence. Now 67, the veteran actress had orthodontic treatment in her 50's to straighten her teeth. Yet she is still conscientious about wearing her retainer. “I wear a retainer every night,” she said. “I got lazy about it once, and then it was very difficult to put the retainer back in. So I was aware that the teeth really do move.”

Indeed they do. In fact, the ability to move teeth is what makes orthodontic treatment work. By applying consistent and gentle forces, the teeth can be shifted into better positions in the smile. That's called the active stage of orthodontic treatment. Once that stage is over, another begins: the retention stage. The purpose of retention is to keep that straightened smile looking as good as it did when the braces came off. And that's where the retainer comes in.

There are several different kinds of retainers, but all have the same purpose: To hold the teeth in their new positions and keep them from shifting back to where they were. We sometimes say teeth have a “memory” — not literally, but in the sense that if left alone, teeth tend to migrate back to their former locations. And if you've worn orthodontic appliances, like braces or aligners, that means right back where you started before treatment.

By holding the teeth in place, retainers help stabilize them in their new positions. They allow new bone and ligaments to re-form and mature around them, and give the gums time to remodel themselves. This process can take months to years to be complete. But you may not need to wear a retainer all the time: Often, removable retainers are worn 24 hours a day at first; later they are worn only at night. We will let you know what's best in your individual situation.

So take a tip from Kathy Bates, star of the hit TV series American Horror Story, and wear your retainer as instructed. That's the best way to keep your straight new smile from changing back to the way it was — and to keep a bad dream from coming true.

If you would like more information about orthodontic retainers, please contact us or schedule an appointment for a consultation. You can learn more about this topic in the Dear Doctor magazine articles “Why Orthodontic Retainers?” and “The Importance of Orthodontic Retainers.” The interview with Kathy Bates appears in the latest issue of Dear Doctor.
