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.

EdenSherandtheLostRetainer

Fans of the primetime TV show The Middle were delighted to see that high school senior Sue, played by Eden Sher, finally got her braces off at the start of Season 6. But since this popular sitcom wouldn’t be complete without some slapstick comedy, this happy event is not without its trials and tribulations: The episode ends with Sue’s whole family diving into a dumpster in search of the teen’s lost retainer. Sue finds it in the garbage and immediately pops it in her mouth. But wait — it doesn’t fit, it’s not even hers!

If you think this scenario is far-fetched, guess again. OK, maybe the part about Sue not washing the retainer upon reclaiming it was just a gag (literally and figuratively), but lost retainers are all too common. Unfortunately, they’re also expensive to replace — so they need to be handled with care. What’s the best way to do that? Retainers should be brushed daily with a soft toothbrush and liquid soap (dish soap works well), and then placed immediately back in your mouth or into the case that came with the retainer. When you are eating a meal at a restaurant, do not wrap your retainer in a napkin and leave it on the table — this is a great way to lose it! Instead, take the case with you, and keep the retainer in it while you’re eating. When you get home, brush your teeth and then put the retainer back in your mouth.

If you do lose your retainer though, let us know right away. Retention is the last step of your orthodontic treatment, and it’s extremely important. You’ve worked hard to get a beautiful smile, and no one wants to see that effort wasted. Yet if you neglect to wear your retainer as instructed, your teeth are likely to shift out of position. Why does this happen?

As you’ve seen firsthand, teeth aren’t rigidly fixed in the jaw — they can be moved in response to light and continuous force. That’s what orthodontic appliances do: apply the right amount of force in a carefully controlled manner. But there are other forces at work on your teeth that can move them in less predictable ways. For example, normal biting and chewing can, over time, cause your teeth to shift position. To get teeth to stay where they’ve been moved orthodontically, new bone needs to form around them and anchor them where they are. That will happen over time, but only if they are held in place with a retainer. That’s why it is so important to wear yours as directed — and notify us immediately if it gets lost.

And if ever you do have to dig your retainer out of a dumpster… be sure to wash it before putting in in your mouth!
