Dental Crowns

What is a dental crown?

When a tooth is cracked, or broken, a complete cover is required to protect the tooth from further fracturing. Also known as a cap, a crown covers all of the tooth’s surface . When checked regularly by your dentist a crown can last between 8-15 years. A veneer, by contrast, only covers the outside surface of the tooth.

Why a crown may need to be fitted.

There are a number of varied reasons for having a crown fitted:

The most common is when a tooth is fractured. A crown will be fitted to minimise the risk of further fracture.

As part of a root canal procedure, quite an extensive volume of tissue may be removed leaving the remaining tissue vulnerable to further fracture or discolouration. A crown not only improves appearance, but can radically increase the time between further treatments by protecting the inner framework of the tooth.

In extreme cases of tooth decay, a crown is a stronger and more secure method of protecting the tooth than a filling. This is because the filling may simply fall out or fracture.

For those patients with unsightly fillings in their front teeth a crown will definitely improve their aesthetic appearance.

Patients who continually grind their teeth will experience chipping and fracturing. Once again, a crown will reduce the risk of further tooth fracture.

If the decision has been made to have a crown, which type will suit you best?

All Ceramic Crown

These are by far the best from an aesthetic point of view and are ideal for the front teeth. Their advantage is that they do not contain any grey metal so if the gums recede after they have been fitted, no grey green metal will be seen.

Here at Brickfields those patients requiring Cerec Ceramic Crowns for aesthetic reasons can be fitted in a single appointment.

It should be noted that most ceramic crowns are as resilient as conventional ones.

Metal Ceramic Crown

With a metal core, providing its strength, the porcelain is bonded onto the metal itself. The main negative to this is that the porcelain itself is not strong and can be prone to fracture.

Metal Ceramic Crowns

Whilst they have a greater strength than ceramic crowns, they tend to be used mainly for the back teeth mainly due to their aesthetics.

All Zirconium Crowns

Again, mainly used for the back teeth they tend to be a brown / yellow colour due to the lack of porcelain. Whilst aesthetically they do not have the best quality of appearance, the chance of fracture is greatly reduced. Furthermore the amount of original tooth tissue necessary to be removed prior to having one of these types of crown fitted is less than for other types. This type of crown is preferential for those situations where a gold crown was fitted in the past.

Gold Crowns

These are by far the strongest type of crown on the market but not the best aesthetically. Again we would mainly use them on the rear teeth. As with Zirconium crowns they require minimal tooth reduction.

How will the dentist decide if I need a crown and what will happen at that point?

  • Step 1: Via x ray to ensure the stability of the root and a full examination to assess the viability of the tooth.
  • Step 2 : The tooth will be prepared to receive the crown and an impression made to enable the lab to produce the crown.
  • Step 3 : A temporary crown will be fitted to protect the tooth in the interim period
  • Step 4 : If the crown is for a front tooth there may be discussion to maximise the colour match
  • Step 5 : Up to 2 weeks later the crown will be fitted
