Crowns

Metal crowns

Metals used in crowns include gold alloy or a base-metal alloy (for example chromium). Compared with other crown types, less tooth structure needs to be removed with metal crowns, and tooth wear to opposing teeth is kept to a minimum.

Metal crowns withstand biting and chewing forces well and probably last the longest in terms of wear down.  The metallic color is the main drawback. Metal crowns are a good choice for out-of-sight molars.

Porcelain-fused-to-metal crowns

Porcelain-fused-to-metal dental crowns can be color matched to your adjacent teeth (unlike the metallic crowns). However, more wearing to the opposing teeth occurs with this crown type compared with metal or resin crowns.

Next to all-ceramic crowns, porcelain-fused-to-metal crowns look most like normal teeth. These crowns can be a good choice for front or back teeth

All-porcelain crowns

All-ceramic (or all-porcelain) dental crowns provide the best natural color match than any other crown type and may be more suitable for people with metal allergies.

However, they are not as strong as porcelain-fused-to-metal crowns and they wear down opposing teeth a little more than metal or resin crowns. All-ceramic crowns are a good choice for front teeth.

Temporary crowns

Temporary crowns can be made in your dentist's office whereas permanent crowns are made in a dental laboratory. Temporary crowns are made of acrylic and can be used as a temporary restoration until a permanent crown is constructed by the dental laboratory.

 

 

 

 

A crown (often called a cap) is an artificial such, shaped to resemble a tooth and made from porcelain, porcelain bonded to a metal base or gold.

 

It is used to restore a tooth which has been heavily filled over a number of years resulting in it becoming weak and/or unsightly, or a tooth that has broken down to a level that a routine filling would not be successful.

 

Equally, crowns can be used to improve the appearance of front teeth that have become heavily worn down or damaged as a result of accident or decay.

 

As long as there is a healthy tooth root present, most teeth can be crowned.
