Crowns are an ideal way to repair 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 example:

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

Most common types of crowns are:

All-ceramic (Emax):
This modern technique offers a metal-free alternative, which can give the strength of a bonded crown and the appearance of a porcelain crown. Therefore it is suitable for use in all areas of the mouth.

Zirconia:
These crowns look natural and can be used anywhere in the mouth. They are very hard wearing and have very good longevity.

Porcelain:
These crowns are made entirely out of porcelain; they function well and has natural-like aesthetics.

Porcelain bonded to precious metal:
This is what most crowns were made from in the past. A precious metal base is made and then porcelain is applied in layers over it.

Gold-alloy crowns:
Gold is one of the oldest filling materials. Today it is used with other metal alloys to increase its strength, which makes it very hardwearing. These crowns are silver or gold in colour.

What is Emax (all ceramic) crown?

This is a type of all-ceramic crown with an appealing translucent colour which is combined with extra strength and durability.

This crown is made from a single block of lithium disilicate ceramic: this is a top grade material which has been harvested for its toughness, durability and opaque qualities which makes it a highly prized crown.

What are Zirconia crowns?

This type of crown is made from zirconia, a very strong material which is compatible with the human body. Zirconia is used in many other medical applications such as artificial joints and is known for its strength and durability.

Zirconia is a type of crystal which is long lasting and indestructible.

Plus there is no fear about the body rejecting zirconia or displaying an allergic reaction to it. It is safe to use and preferred by many people to porcelain fused to metal crowns.
