A crown restoration is a fabricated replica of a natural tooth. The mechanics and methods to prepare the tooth and attach the new crown are standard procedures in dentistry. But the crowns themselves — their individual shape, color and material from which they’re constructed — can differ greatly depending on each patient’s individual needs and desires. All these factors can have a bearing on cost — not to mention the process a dentist may employ to produce a custom crown.
Crowns are usually fashioned by a dental laboratory technician using castings of the patient’s mouth prepared by the dentist. These professionals should be considered artists as well as scientists. And, like artists with certain areas of strength and expertise, individual technicians may also develop high practical skill for a particular type of tooth replacement; it’s not uncommon for a dentist to use a different dental technician for a particular type and size of tooth to be restored. This could prove to be a factor in the final cost.
The efforts to create the best color in the crown can also affect cost. While we think of teeth as uniformly “pearly white,” there really are variations and gradations in normal tooth color (even within the same tooth). Again, a bit of artistry is important here, as the dentist communicates with the technician on not only the color but also the subtle hue gradations along the length of the crown. Your input as a patient is also valuable in determining color — you must be satisfied with the final product. Fortunately, it’s now possible to take a “test drive” of your potentially new look with a provisional crown that will allow you to see just how your permanent crown (which will be made of longer-lasting, higher quality materials) will appear.
These factors, as well as the limitations you may face by your insurance coverage, can greatly influence the final cost of treatment. As your dentist, we will consult and work with you to find the best crown restoration option that will fit both your dental needs and your financial ability.

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.
