Why are dental crowns used?

Crowns are indicated to provide a more secure restoration for teeth with extensive fillings and/or weakened or fractured cusps. Sometimes gold or porcelain onlays may also serve the same purpose.

Not infrequently the existing restoration is removed and a composite bonded build-up of the tooth is performed to create a solid secure decay-free bonded foundation for the crown. Also depending on the size of the restoration, proximity to the nerve area and existence of fracture lines, it may be indicated to electively have root canal treatment performed prior to placing the crown.
If you want a smile that's your crowning glory, you may need a crown to cover a tooth and restore it to its normal shape and size. A crown can make your tooth stronger and improve its appearance.

It can cover and support a tooth with a large filling when there isn't enough tooth left. It can be used to attach a bridge, protect a weak tooth from breaking or restore one that's already broken. A crown is a good way to cover teeth that are discolored or badly shaped. It's also used to cover a dental implant.

If your dentist recommends a crown, it's probably to correct one of these conditions. Your dentist's primary concern, like yours, is helping you keep your teeth healthy and your smile bright -- literally, your crowning glory.

Dental crowns are used when there is not enough tooth structure left to support a simple filling. Crowns cover the entire tooth and provide support for the tooth when too much tooth structure has been lost to decay or trauma.
A dental crown is usually placed on a tooth that has been damaged by trauma or decay and cannot be fixed with a simple filling. They can, in some cases, be used to improve the appearance of natural teeth that have been discolored.
