We are pleased to have own our very own in-house state of the art CEREC® 3D ceramic studio which allows us to make custom-made crowns on site in just one appointment.
CEREC 3D Ceramic Studio
Using Computer Aided Design (CAD) technology, our CEREC® machine allows us produce any kind of tooth restoration in just one hour.
Restorations can include crowns and veneers (for chipped and discoloured teeth) and inlays and onlays (for broken down molars).
The crown fits right over the remaining part of the tooth, making it strong and giving it the shape and contour of a natural tooth.
Crowns are sometimes also known as ‘caps’. An ‘Anterior Crown’ is a crown fitted to the front eight teeth.
There are a number of reasons to have a crown:
- the tooth may have been weakened by having a very large filling
- 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 it
- you may have had an accident and damaged the tooth
- it may help hold a bridge or denture firmly in place.
“All the staff there are extremely friendly and helpful … the environment is extremely pleasant – most of my friends have changed over to the Brunel surgery and they are as happy as I am! Going to the dentist is now no longer something to fear!”

Crowns - FAQs
What are crowns made of?
They are made of a variety of materials and new materials are being introduced all the time. Here are some of the options available at present:
Porcelain bonded to precious metal: this is what most crowns are made from. A precious metal base is made and layers of porcelain are then applied over it.
Porcelain: These are not as strong as bonded crowns but they can look very natural and are most often used for front teeth.
Porcelain and composite: porcelain and composite resin materials can sometimes look the most natural. However, these are not as strong as bonded metal crowns.
Glass: these look very natural and are used on both front and back teeth.
Precious metal (gold and palladium): these are very strong and hard-wearing, but are not usually used at the front of the mouth, where they are highly visible.
How is a tooth prepared for a crown?
The dentist will prepare the tooth to the ideal shape. This will mean 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 to be fitted.
Once the tooth is shaped, the dentist will take an impression of the prepared tooth, one of the opposite jaw and possibly another to mark the way you bite together.
The impressions will be given to the technician, along with any other information they need to make the crown.
Who makes the crown?
The impressions and information about the shade of your teeth will be given to a dental technician who will be skilled in making crowns.
They will make models of your mouth and make the crown on these to be sure that the crown fits perfectly.
Will the crown be noticeable?
How long does the treatment take?
Does it hurt to have a tooth prepared for a crown?
No. A local anaesthetic is used and the preparation should feel no different from a filling. If the tooth does not have a nerve, and a post crown is being prepared, then local anaesthetic may not be needed.
Are post crowns different?
Post crowns may be used when the tooth has been root filled. The weakened crown of the tooth is drilled off at the level of the gum. The dentist makes a double-ended ‘post’ to fit into the root canal. This can be either prefabricated stainless steel or custom made of gold.
One end of the post is cemented into the root canal, and the other end holds the crown firmly in place.
Are there any alternatives to post crowns for root-filled teeth?
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.

Is there an alternative to a crown?
A veneer may be an alternative to having an anterior crown.
