Crowns and Bridges

Crowns

Dental crowns are the ideal restoration for teeth that have broken, or have been weakened by decay or a very large filling. The crown completely covers and protects the tooth underneath and restores it to its proper shape and size. Without placing a crown over the damaged natural tooth, the natural tooth might eventually disintegrate because it is so weak.

Crowns are also used to change the shape of teeth. If you have very large gaps between the teeth, the teeth are significantly out of alignment, the teeth are significantly discoloured or the teeth are crooked, then crowns are what you need.

Crowns can be made from a variety of different materials and are fixed in place with special dental adhesive.

Zirconium Oxide Crowns

Fantastic quality and aesthetics.

Zirconium oxide is a very strong material and is used in the manufacture of our Zeno zirconium oxide crowns and bridgework. These crowns will not corrode and the normal black gum line that you might see around some other crowns, will not occur.

Zirconium Oxide crowns are much less sensitive in the mouth than some other crowns and uncomfortable hot and cold sensations which you might feel with other crowns do not normally occur. Patients with allergies will not normally suffer from any adverse reactions with these crowns.

Our Zirconium Oxide crowns look fantastic. Side by side with a natural tooth it is very hard to detect which is the natural tooth and which is the zirconium oxide crown. You will be utterly amazed by the results.

Porcelain Fused to Metal Crowns

Porcelain covered crowns (otherwise known as porcelain on metal crowns, or porcelain fused to metal crowns) are often used for back teeth. The metal substructure gives strength and support to the porcelain but the metal layer reduces the translucency of the crown making it appear opaque and duller than a natural tooth.

Gradia Crowns

Gradia is a unique light cured micro ceramic composite system for crowns, bridges, inlays and veneers. Gradia gives an excellent aesthetic look compared with conventional composites.

Procedure

After the area has been numbed, the tooth that is to be crowned is prepared by grinding it to a certain shape so that it can support the new crown. An impression is made of the prepared tooth and gum, and a temporary crown is normally placed on top of the prepared tooth. The temporary crown gives the prepared tooth a much better look and it also helps with reducing any sensitivity in the area. The lab makes the permanent crown from the impression that has been taken and 5 days later the temporary crown is removed and the permanent new crown is fitted.

A bridge is a number of crowns joined together which allows one or more missing teeth to be replaced without using a denture or dental implant. The missing tooth is replaced with a pontic tooth, which is fused between two crowns that are permanently attached to the adjacent teeth. So the new tooth is held in place by being attached on each side to an adjacent crowned tooth.

The disadvantage of bridges is that the teeth either side of the gap have to be crowned in order to accept the bridge. However without a bridge or implant the unsupported teeth will tend to tilt toward the gap altering the alignment of the occlusion and reducing the efficiency of the bite.
