Here’s the full lowdown on the dental crown and its various elements. 

We’ve got a great response to our ‘back to basics’ series of blogs that explained some core dental treatments in very simple terms. So today, it's the turn of teeth crowns – also commonly referred to as dental crowns.
 

So let’s start at the very beginning. In very simple terms, the anatomy of any tooth is basically made up of two separate elements – the root and the crown.
 

And assuming that you’ve got a good, healthy mouth, the root of the tooth should be covered by a combination of bone and gums.


The part of the tooth that’s visible in the mouth, however, is known as the clinical crown. It follows, therefore, that an artificial tooth that either completely or partially covers the outside of the clinical crown is known by dentists around the world as a dental crown. You may also hear it referred to as a cap.
 

The first issue that might occur to you is that if you place a crown or cap on top of an existing tooth, surely it will be too big – and out of scale with your existing teeth? Quite right – but your dentist takes this into account. He pares back the original tooth to make sure that when the crown is placed over it, it will equate to the original size of your tooth.
 

This process is known as preparation, and differs from case to case, depending on the state of the tooth to be treated. Does it have fillings, for example, or is there a root canal in place.
 

One of the main challenges facing your dentist is making sure that the ‘margin’ is correct. This refers to where the edge of your new crown meets newly prepared surface of the damaged tooth. Obviously, it needs to be very smooth, with no unsightly gaps or uncomfortable surfaces.
 

Your dentist also needs to make sure that the ‘cusps; of the crown are correctly formed. The cusps are the pointy parts of your crown – the bits you use for biting into food and chewing it. If the original cusps of your teeth are damaged, then a crown is the obvious solution.
 

In terms of the common forms of crown that you’ll come up against, a partial crown or onlay will only cover some of the cusps of the teeth. This is the preferred treatment if the entire range of cusps are not in need of restoration.
 

Another type of crown is a dental veneer. In this case, it only covers the front of the tooth and the biting surface. They are equally successful at changing the colour or changing the shape of a tooth, so are often used on crooked teeth to restore a sense of symmetry and balance.
 

There are a number of different substances used in the creation of crowns, and you can choose from PFM (porcelain fused to metal, E.max (full porcelain) or zirconium crowns.
 

But whichever type you choose, you can take solace in the fact that tooth crown prices are highly affordable, starting at just €350 a pop.
