Crowns

A dental crown also known as a "cap" is a structure that is tooth shaped that is cemented over a tooth or an implant in order to restore form and function.

Crowns can be made of different materials some of which are tooth coloured and some of which are silver coloured or gold coloured.

There are several reasons as to why a crown may be recommended for your treatment:

  1. To strengthen the tooth where a large filling is already in place and that large filling is at risk of fracture and failure.
  2. To protect the tooth that is already weak.
  3. To restore a tooth that may have fractured as a result of trauma for a tooth that has been subject to excessive wear.
  4. Often when a tooth has had a root canal treatment done a crown is a recommended restoration of choice in order to restore the strength and integrity of that tooth.
  5. Crowns may be provided for cosmetic reasons where teeth are particularly discoloured or poorly shaped or misaligned.

Metal crowns may be made of materials including alloys of gold or other non-precious medal based alloys. These type of crowns require the least amount of tooth substance to be removed because the metal base is in thin section. Metal based crowns are very good at taking biting forces and are very good crowns to be placed in the back molar regions where aesthetics are not so important but chewing strength is.

Porcelain fused to metal crowns are very good choice for both anterior and posterior teeth. They can be colour matched to one's own existing teeth.

Metal free all ceramic crowns represent the ultimate in high aesthetics and superb looks. They are a very good choice for front teeth although they are not as strong as porcelain fused to metal crowns.

A crown is normally made over two visits. At the first visit the tooth is prepared and an impression taken of that prepared tooth. The crown is made by a dental technician after the impression of the prepared tooth is sent to a dental laboratory. At the second visit the crown is cemented onto the prepared tooth. In between the preparation and cementation visits a temporary crown is made to preserve form and function.

Here at Langley Dental Practice we have wide experience in offering the different types of crowns described whether on an NHS or independent basis.
