Why Is a Dental Crown Needed?

A dental crown may be needed in the following situations:

  1. To protect a weak tooth (for instance, from decay) from breaking or to hold together parts of a cracked tooth
  2. To restore an already broken tooth or a tooth that has been severely worn down
  3. To cover and support a tooth with a large filling when there isn't a lot of tooth left
  4. To hold a dental bridge in place
  5. To cover misshapen or severely discolored teeth
  6. To cover a dental implant
  7. To protect a root canalled tooth.

What Types of Crowns Are Available?

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 (for example, palladium) or a base-metal alloy (for example, 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. Metal crowns withstand biting and chewing forces well and probably last the longest in terms of wear down. Also, metal crowns rarely chip or break. The metallic color is the main drawback. Metal crowns are a good choice for out-of-sight molars.
     
  • 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. The crown's porcelain portion can also chip or break off. Next to all-ceramic crowns, porcelain-fused-to-metal crowns look most like normal teeth.
     
  • 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.

What Steps Are Involved in Preparing a Tooth for a Crown?
Preparing a tooth for a crown usually requires two visits to the dentist -- the first step involves examining and preparing the tooth, the second visit involves placement of the permanent crown.

You will wear a temporary crown while your final crown is being made.

How Should I Care for My Temporary Dental Crown? Because temporary dental crowns are just that -- a temporary fix until a permanent crown is ready, most dentists suggest that a few precautions be taken with your temporary crown. These include:

  • Avoid sticky, chewy foods (for example, chewing gum, caramel), which have the potential of grabbing and pulling off the crown.
  • Minimize use of the side of your mouth with the temporary crown. Shift the bulk of your chewing to the other side of your mouth.
  • Avoid chewing hard foods (such as raw vegetables), which could dislodge or break the crown. Slide flossing material out-rather than lifting out-when cleaning your teeth. Lifting the floss out, as you normally would, might pull off the temporary crown
