AStainlessSteelCrownCouldHelpaStrugglingPrimaryMolarLastLonger

Although primary (“baby”) teeth have a lifespan of only a few years, they’re still important to a child’s current and future dental health. In the present, they help a child eat, speak and smile properly. They also help create a healthy future as placeholders for developing permanent teeth yet to come in.

If, however, a child loses a primary tooth prematurely due to decay, the corresponding permanent tooth could come in misaligned. That’s why we do what we can to help a decayed primary tooth reach its full lifespan. And there are different ways to do this depending on the type of tooth.

With front teeth, which don’t encounter the same chewing forces as those in the back, we may use a tooth-colored filling. This approach is also preferable for appearance’s sake since front teeth are highly visible when a child speaks or smiles.

Primary molars, on the other hand, need a more robust solution. A filling may not be able to withstand the level of long-term chewing forces that these back teeth normally encounter. And because they’re less visible than front teeth, there’s less concern about aesthetics.

That’s why many pediatric dentists prefer stainless steel crowns for molars. Just like their permanent teeth counterparts, a primary crown fits over and completely covers a tooth. They’re typically pre-formed, coming in different shapes and sizes that can then be customized for the tooth in question. After preparing and removing any decayed material from the tooth, we can usually install the crown in one visit with local anesthesia and a sedative (if the child needs it for anxiety).

While a steel crown isn’t the most attractive restoration, it typically handles the higher chewing forces in the back of the mouth better and longer than a filling. That’s especially critical for primary molars, which are some of the last teeth to fall out (as late as ages 10-12).  And besides preserving it as a permanent tooth placeholder, a crown also helps the tooth function effectively in the present.

Regardless of what method we use, though, preserving primary teeth is a primary goal of pediatric dentistry. And with a stainless steel crown, we can keep those important back molars functioning for as long as they’re intended.

WhatsYourCrownMadeOf

Like the ones worn by kings and queens of old, dental crowns were traditionally made of that most “royal” of metals: solid gold. This style of crown is still going strong after over a hundred years, but recent advances may have stolen some of its luster. Want to learn more about the different materials from which crowns can be made? Read on!

Gold crowns have stood the test of time, and many still consider them the best. Gold is one of the earliest materials to be successfully used for making crowns, and when properly done, it also lasts the longest: over 50 years in some cases. For these and other reasons, many dentists prefer to get gold restorations for their own teeth.

But in recent years, the use of gold crowns has been in decline — especially when the crown is for one of the front teeth. Why? In one word: aesthetics! With the advent of porcelain and porcelain-fused-to-metal (PFM) crowns, many people have opted to go with these more natural-colored tooth restorations.

PFM restorations have been in use for some four decades. They combine the strength of precious metals (gold or platinum) with the appeal of a finish that appears more like a natural tooth. With proper care, a PFM restoration may have a functional life of around 20 years.

With their pearly luster and semi-translucent sheen, all-porcelain crowns have an incredibly lifelike appearance. Porcelain itself is a glass-like material, which is specially modified to add strength when it's used in dentistry. In the past, there were some problems with brittleness in all-porcelain restorations. Today, newer formulations have been designed to avoid these issues.

High-tech materials that have recently become available to dentistry include a polycrystalline ceramic substance called zirconium dioxide or “Zirconia.” It shows great promise in terms of aesthetics and strength, and is the subject of much ongoing research. One day, it may replace other materials and become the new “gold standard” of crowns.

Depending on the particular situation, one or more of these materials may be considered for your crown.
