If your tooth is damaged but not lost, a crown can be used to restore its shape, appearance and function. You may need a crown if you have a root canal, a large filling in a tooth or a broken tooth.

A crown is a hollow, artificial tooth used to cover a damaged or decayed tooth. The crown restores the tooth and protects it from further damage. Crowns can also be used to cover a discoloured or misshapen tooth. A tooth that has been fixed with a crown looks and works very much like a natural tooth.
All Ceramic Crowns
These are a type of cosmetic crown which are made purely from ceramic and no other material. This is in contrast to other types of crowns such as the porcelain fused to metal variety and gold crowns.
The defining feature of these crowns is that they are made from a translucent material which is attractive to look at and blends in well with the rest of your teeth.
This means a top quality crown which will last for many years. The majority of all ceramic crowns are produced using computer technology, e.g. CAD/CAM technology which is based upon 3D design.
There are two types of ceramic crowns:
Advantages of a Zirconia Crown
There are three advantages which are:
Strength: zirconia crowns last longer than other types of crowns.
Aesthetics: these crowns have an attractive translucent colour which blends in well with the other teeth.
Retain more of the existing tooth: minimal preparation is required which means more of the original tooth is preserved. This is useful if the crown needs to be removed.
So, a good choice if you are looking for a strong, long lasting and visually appealing crown. They are ideal at covering signs of damage or staining as well as helping to maintain the function of the tooth.
Advantages of a E-Max Crown
This crown is considered to be the best match with your own natural teeth. The transparent colour and lifelike shape ensures that it is unlikely to be noticed amongst your own natural teeth.
There is no metal alloy base with this crown which means no unsightly looking grey line around the gum line.
They are strong, long lasting and unlikely to crack or fracture as compared to many other types of crowns. They are considered to be at less risk of chipping compared to zirconia crowns.
