Dental Crown / Bridges in Balwyn North

What is a crown?

A crown is an artificial restoration that fits over the remaining part of a prepared tooth, making it strong and giving it the shape of a natural tooth. A crown is sometimes known as a ‘cap’.


Why would I need a crown?
Crowns are an ideal restoration for teeth that have been broken, or have been weakened by decay or a very large filling. A crown could be used for a number of other reasons, for instance:

  • You may have discoloured fillings and would like to improve the appearance of the tooth
  • You may have had a root filling which will need a crown to protect what is left of the tooth
  • It may help hold a bridge or denture firmly in place

Crowns can be made of a variety of different materials and new materials are continually being introduced.

Some of the most popular options are listed below:

  • Porcelain bonded to metal: this is what most crowns are made from. A metal base is made and then porcelain is applied in layers over it.
  • Porcelain crowns: these crowns are made entirely out of porcelain. They can look very natural and are most often used for front teeth.
  • Zirconia crowns: this modern ceramic material offers excellent aesthetic, where also strength needed.
  • Gold alloy crowns: gold is one of the oldest dental materials. Today it is used with other metal alloys to increase its strength, which makes it a very hard wearing restoration. These crowns are silver or gold in colour.
  • Alloys containing stainless steel, cobalt chromium or nickel chromium
  • black lines at the top of the crowns
  • opaque, flat, dead looking teeth that stand out like sore thumbs
  • misshapen “teeth” with big black triangles either side
  • swollen gums around in-precise crowns that never fitted properly

Our family dentist in Balwyn will prepare the tooth to the ideal shape for the crown. This will involve removing most of the outer surface, and leaving a strong inner core. The amount of the tooth removed will be the same as the thickness of the crown.

Once the tooth is shaped, the dentist will take an impression (mould) of the prepared tooth, one of the opposite jaw and possibly another to mark the way you bite together.

The impressions will then be given to the dental technician, along with an appropriate shade and other information needed for the crown to be made.

In root-filled teeth it may be necessary to insert a post before placing a crown. A post provides support and helps the crown stay in place. The weakened crown of the tooth may be shortened to gum level. A post can be made of prefabricated stainless steel or Carbon fibre which the dentist can fit directly into the root canal, or a custom-made post can be constructed by the dental technician to accurately fit the shape of the prepared root canal. The post is placed into the root canal and cemented in position, ready for the crown to be attached.

If a root-filled tooth is not completely broken down, it may be possible to build it up again using filling material. This ‘core’ is then prepared in the same way as a natural tooth and the impressions are taken.

A temporary crown will be made so that you can use the tooth while you wait for the crown to be made. This crown may be more noticeable but is only a temporary measure.

When you and our dentist are happy with the fit and appearance of the new crown it will be fixed in place with special dental cement or adhesive. The cement forms a seal to hold the crown in place.

You will need to have at least two visits: the first for the preparation, impression, shade taking and fitting the temporary crown; and the second to fit the permanent crown. There will usually be about 2 weeks in between appointments.

No. A local anesthetic is used and the preparation should feel no pain. If the tooth does not have a nerve, and a post and/or crown is being prepared, then a local anesthetic may not be needed.

The crown will be made to match your other teeth as closely as possible. The shade of the neighboring teeth will be recorded, to make sure that the colour looks natural and matches the surrounding teeth.

Because the shape of the crown will be slightly different from the shape of your tooth before it was crowned, you may be aware of it to begin with. Within a few days it should feel fine, and you will not notice it. The crown may need some adjustment if your bite does not feel comfortable, and if this is the case, you should ask our dentist to check and adjust it.

Costs will vary according to the type of crown and material used. It is advisable to get a written estimate and treatment plan before beginning any dental treatment.

How long your crown lasts depends on how well you look after it. The crown itself cannot decay, but decay can start where the edge of the crown joins the tooth. Therefore, it is important to keep this area just as clean as you would your natural teeth in order to prevent decay affecting the crown.

Properly cared for crowns should last for many years. Our dentist at Beautiful smile will be able to tell you how long the crown may be expected to last.
