Dental crowns

Dental crowns and bridges are used to restore the shape, function and appearance of natural teeth. In most cases, it is impossible to make the distinction between the restoration and patients’ own teeth.

Crowns are fitted as prosthetic coverings to those teeth that no longer possess enough integrity to support fillings. They are an ideal way to repair broken teeth or teeth weakened by decay or a large filling.

Dental Crowns

What is a crown made of?

Dental crowns can be made of a variety of materials and as dentistry evolves new manufacturing options are continually being introduced.
The normal range of crown materials include:

Porcelain bonded to precious metal – the most commonly used dental crown. Here a precious metal base is made and then porcelain is applied in layers over it.

Porcelain – these crowns are metal free and are made entirely out of porcelain. They look very natural and are favoured for use on front teeth.

All-ceramic – a modern technique that also offers a metal-free prosthetic, giving the strength of a bonded crown and the appearance of a porcelain crown.
Glass – these can be used anywhere in the mouth and aesthetically are excellent.

Gold-alloy crowns – one of the oldest options. These can be gold or silver in colour and are very strong.

Preparation of dental crowns

Our dentists will sculpture a suitable bonding bed on the tooth to be restored. This will involve removing a layer of the outer surface, leaving a strong inner core. The amount of the tooth drilled away will usually be the same as the thickness of the crown.

An impression of the prepared site and surrounding bite is taken from which the dental technicians can make the crown.

To preserve our dental preparation work a temporary crown will be fitted while the final one is made in the laboratory.

What is a post crown?

In root-filled teeth, it may be necessary to cement a post into the tooth root before placing a crown. This allows additional support and helps the crown to stay in place.

A prefabricated stainless steel post can be fitted directly into the root canal, but occasionally a custom-made post to accurately fit the shape of the prepared root site needs to be constructed.

How many appointments?

The complete dental crown restoration will normally take at least two visits to our North Street Dental and Implant Clinic in Dudley. However, if root canal therapy is required on the tooth being crowned, more appointments may be required.

How is the crown fixed?

When our dentists are completely happy with the fit and appearance of the new crown, it will be fixed in place with dental cement.

Caring for a dental crown

A dental crown cannot decay, but problems can emerge where the edge of the crown joins the tooth and around the gum line if oral hygiene is poor. A regular brushing and flossing regime is required. Properly cared for, crowns should last for many years.
