Okay, so no one is ever very excited to hear that they need a crown. But if and when you do, you’ll want to be prepared with some research on what options are available.
The Classic Metal Crown
When you picture a dental crown, you might think of a gold tooth. Gold and other metals are used to produce very reliable, long-lasting, and highly-visible crowns. A metal crown is usually preferred on a back tooth in terms of strength and appearance.
The Natural Porcelain or Ceramic Crown
These crowns look realistic because they have no metal in them. That’s also important if you have a metal allergy or the crown will be visible. Porcelain and ceramic look great, but aren’t as strong as metal. These crowns are happiest on front teeth in the smile-zone!
The “Best of Both Worlds” Crown
Many crowns are made of a metal core and have porcelain baked over them for an aesthetic finish. Also called porcelain-fused-to-metal or PFM crowns, these are very strong restorations.
So strong, in fact, that they can wear down the opposite teeth. And with time your gums could recede, exposing the dark metal underneath.
The Resin Crown
If you’re looking for the most cost-effective solution, then a resin crown is the way to go. Full resin crowns will look nice. They won’t stand out the way a metal crown will, and they’re relatively inexpensive. The big catch is that a resin crown will wear and fracture and require replacement much sooner than any of your other options.
Equipped with some pros and cons, you can discuss crown options with your dentist and confidently choose the one that’s right for you!

When a tooth is cracked or chipped and the root remains intact, your dentist may build a crown to help preserve the remainder of the tooth and the overall structure of your teeth. But just like the ones you wear on your head, not all are built the same.
Here are the most common types of crowns:
Gold crowns are the strongest of all types, and are usually the most expensive. Because of the flashy nature of the gold alloy, this type of crown is usually reserved for the molars at the back of the mouth, hidden from view.
Other types of metal crowns include stainless steel, which is used primarily for temporary crowns because of its softness, and other types of metal alloys including chromium and nickel. Beyond strength and durability, metal crowns require less tooth restructuring than other crown materials and so much of the existing tooth and neighboring teeth remain intact.
Popular choices for crowns nowadays include all-porcelain or all-ceramic. The biggest advantage to porcelain crowns over metal is that they can be matched to existing teeth. However, a big disadvantage is that they require more preparation of the tooth and surrounding teeth and they don’t last as long as metal. Sometimes, the porcelain types can be combined with a metal base for extra strength, but then you sacrifice a little in terms of aesthetics.
Resin is another popular choice for crowns. It, too, can be matched to the color of your teeth. But resin crowns can be prone to cracking and chipping, and with this type you may find yourself having to replace the crown sooner than you’d like.
The type of crown you ultimately choose is going to be based on where the crown is located in your mouth, the price and durability. Also, if you have any metal allergies, your dentist will probably have you rule out gold and other alloys.

Options have soared over the last decade in all areas of dental restorations. Dental crowns are right at the top of the list.
A dental crown is a restorative oral prosthesis. There are several types of crowns and each crown type uses a unique make-up of materials. Your dentist will explain each option available to you. Together, you will decide the best treatment plan.
Stainless Steel Crown
Stainless steel crowns are usually done as a temporary measure. A dentist will place a stainless steel crown on a primary tooth when there is a lot of decay present. A baby tooth is not strong enough to support a large filling and the child needs to retain this primary tooth for a year or more. When baby teeth are extracted too soon, the other teeth can drift or shift out of place. This would cause serious consequences when the permanent tooth erupts. The stainless steel crown holds this space.
Gold Crowns and Porcelain Fused To High Noble Metal Crown
The benefit of the gold crown and the porcelain fused to high noble metal crown is their durability. The gold crowns rarely chip or break. Another benefit, less tooth structure has to be taken away in preparation of the crown. The drawback is the metallic color. Porcelain fused to metal crown is colored matched to the adjacent teeth; however, the metal can show as a dark line next to your gum. The porcelain fused to metal is more fragile than gold. The porcelain can chip off or break. These two types are good choices for out of sight teeth.
All Ceramic / All Porcelain Crown
Porcelain crowns provide the best color match to your natural teeth. They are also a good option for people with metal allergies. This is an excellent choice for front teeth. These crowns are not as durable as porcelain fused to metal crowns, and they can wear down opposing teeth more than metal crowns.

When you are getting a dental crown to restore a damaged tooth, you have a choice of the type of material used to fabricate the crown. Metal crowns have been used for decades and are still an excellent choice. They are easy to work with and very durable. They rarely crack or chip and wear at about the same rate as natural teeth.
The problem with metal crowns is their gold or silver color. Most people find metal crowns unattractive, especially when they are placed on one of the teeth that show when smiling. Porcelain or ceramic crowns are a more attractive alternative, but these types of crowns are more likely to crack or chip under normal chewing pressure. In addition, they can cause excessive wear on opposing teeth that come in contact with the crown.
An excellent compromise is a porcelain-fused-to-metal crown. These have a metal base with a layer of porcelain fused to the surface and offer the durability of a metal crown with the cosmetic appeal of a porcelain or ceramic crown. These types of crowns look almost as good as a porcelain or ceramic crown but they are far more durable.
One downside is that a porcelain-fused-to-metal crown has the same wear issue as a porcelain crown, but if excessive wear is a concern, the crown can be made with a porcelain veneer on the most visible part of the crown while leaving the contact area bare metal.
Another problem with porcelain-fused-to-metal crowns is the thin metal strip along the edge of the crown. In most cases, the dentist will place the crown so that the silver or gold colored strip is below the gum line where it cannot be seen, but in some cases it is still visible, especially if the patient’s gums start to recede.
