A dental crown is a tooth-shaped "cap" that is placed over a tooth - covering the tooth to restore its shape and size, strength, and/or to improve its appearance.

The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line.



  • To protect a weak tooth (for instance, from decay) from breaking or to hold together parts of a cracked tooth

  • To restore an already broken tooth or a tooth that has been severely worn down

  • To cover and support a tooth with a large filling when there isn't a lot of tooth left

  • To hold a dental bridge in place

  • To cover misshapen or severely discolored teeth

  • To cover a dental implant

  • ​Permanent Crowns 

    • Can be made from all metal, porcelain -fused-to-metal, all resin, or all ceramic

  • Metals Used in Crowns

    • Include gold alloy, other alloys (like palladium), or a base-metal alloy (like nickel or 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

    • Withstand biting and chewing forces and typically last the longest in terms of wear down

    • Rarely chip or break

    • Metal crowns are a good choice for out-of-sight molars because the metallic color

  • Porcelain-Fused-to-Metal Crowns

    • Next to all-ceramic crowns, porcelain-fused-to-metal crowns look most like normal teeth.

    • The metal underlying the crown's porcelain can show through as a dark line, especially at the gum line and even more so if your gums recede 

      • Can be a good choice for front or back teeth.

    • Can be color matched to your adjacent teeth (unlike the metallic crowns)

    • Wearing to the opposing teeth occurs with this crown type compared with metal or resin crowns

    • The crown's porcelain portion can also chip or break off

  • All-Resin Crowns 

    • Less expensive than other crown types

    • Wear down over time and are more prone to fractures than porcelain-fused-to-metal crowns

  • All-Ceramic or All-Porcelain

    • Provide the best natural color match than any other crown type and may be more suitable for people with metal allergies 

    • 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 vs. Permanent 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 or stainless steel

      • Can be used as a temporary restoration until a permanent crown is constructed by the dental laboratory
