What types of dental crowns are available?

Many patients require dental crowns if they have suffered from serious damage or decay, have had a root canal or are having implant surgery. A dental crown is a tooth-shaped cap that is placed over a tooth in order to restore the tooth’s shape, size, strength, functionality and appearance. A dental cap holds a weak tooth together so that it can continue to endure the constant work of chewing.

If you have to have a dental crown placed over one of your teeth, you’ll likely have the opportunity to choose between the different types of dental crowns. In this post, we’ll go over the types of crowns and what issues you’ll need to consider when making your decision.

Different types of crowns 

The different types of crowns that we offer at Randwick Dental Clinic in Sydney are metal, porcelain-fused-to-metal, all ceramic (all porcelain) and all resin. They each have their advantages and disadvantages.

Metal

With metal caps, less of the tooth structure needs to be removed and there is much less wear to the opposing teeth. In addition, metal is probably the strongest material, so it endures biting and chewing well and takes the longest to wear down, rarely chipping or breaking.

One the other hand, the metallic colour is often less desired because it is not natural and will be more noticeable.

Porcelain-fused-to-metal 

This option gives you the best of both worlds. You get the strength of a metal crown with the appearance of porcelain, which can be colour matched to adjacent teeth so that it looks the most natural.

However, because the top layer is porcelain and not metal, more wear and tear to adjacent teeth can occur, and porcelain can chip.

All Ceramic/All Porcelain 

Porcelain dental crowns provide the most natural-looking option, and they are ideally suited for people with metal allergies.

But again, there will be more wear and tear on adjacent teeth, and ceramic is not as strong as its metal counterparts.

All-Resin 

The main benefit of an all-resin crown is that it’s the cheapest option. However, it is the most prone to wear down and suffer fractures.

 

Considerations when choosing a crown material 

When deciding on the crown material, there are a few things that you should consider. The material you select is made in accord to clinical demands, aesthetic demands, strength requirements, material durability and restorative space available.

If, for example, you need a crown for a back molar, you might want to choose a gold or metal crown as the unappealing colour will be hidden from sight, and these materials will provide the most strength and durability in the face of daily chomping.

For front molars, you might consider a porcelain-fused crown, as this will give you a lot of the same strength as a metal crown with the aesthetics of a porcelain crown.

How is your budget? Dental crowns can cost you a bit of money, so if you need to watch your wallet, you might consider an all-resin or porcelain crown, as these are the cheaper options.
