A dental crown is essentially a cap placed over the tooth. Crowns can be used for various reasons, including:

  • To repair a worn or broken tooth
  • To protect a weak tooth
  • To cover a tooth that has a filling when there isn’t much tooth left to support it
  • To hold a dental bridge in position
  • To cover an implant
  • For cosmetic reasons, to cover discolored or oddly shaped teeth

To prepare for your tooth for a crown, the Dr. Zachery Green inspects your teeth and takes x-rays to ensure that your entire tooth is healthy enough for a crown. Then Dr. Green uses a local anesthetic to numb the area before reshaping your tooth. The tooth is filed down just enough to make room for the crown. If part of the tooth is missing, the Dr. Green may need to build up the tooth in that location in order to support the crown. Impressions of your teeth are then taken and sent to a laboratory to fabricate the crown. Dr. Green will place a temporary crown on your tooth to protect it until the permanent crown is ready.

Once the crown is ready, you will go back in for your second visit. The temporary crown is removed and the permanent crown is tested for color and proper fit. Once it has been tested, Dr. Green will apply local anesthetic and cement the crown in place.

There are various materials used to fabricate dental crowns. At Denteffex in Cheyenne, Wyoming, we use the following materials depending on the patient’s particular situation:

All-Porcelain Crowns

All-porcelain crowns match your natural tooth color better than any other crown type. There are many types of all-porcelain crowns. Their main advantage is esthetics, but now the Zirconia and Impress Emax all-porcelain crowns are just as strong, or stronger, than porcelain-fused-to-metal crowns. They can be milled from a single block of porcelain by a computer guided mill, and are very exact and esthetic.


Like all-porcelain crowns, porcelain-fused-to-metal crowns can be color-matched to your natural teeth. Because they are strong, they are a good choice for front or back teeth.

Gold Crowns

Gold crowns withstand normal biting and chewing very well and therefore typically are the longest lasting type of crown. Since this type of crown has a metallic gold color, it is normally only used on molars that cannot be seen.
