What is a Crown?

Sometimes a crown or cap may need to be placed over an existing tooth. A crown restores the tooth to its normal shape, size and function, makes the tooth stronger or improves the way the tooth looks. Crowns can be made from several types of materials, including: zirconia, metal alloys, ceramics, porcelain, composite resin, or combinations of these materials. A crown is often colored to blend in with your natural teeth. We are happy to explain the different types of materials so that you can make the best choice based on your needs, probable crown longevity and budget.

When are crowns necessary?

  • You have a cavity that is too large for a filling
  • You need to cover a dental implant
  • You have a tooth that is cracked, worn down or otherwise weakened
  • You have had root canal treatment—the crown will protect the restored tooth
  • You want to cover a discolored or badly shaped tooth and improve your smile

What is a Fixed Dental Bridge?
Dental bridges bridge the gap created by one or more missing teeth. A dental bridge is made up of two or more crowns for the teeth on either side of the gap, with a false tooth or several teeth in between. These false teeth can be made from gold, alloys, porcelain, or a combination of these materials. Dental bridges are supported by natural teeth or implants.

The process of making a crown or dental bridge includes a number of steps, beginning with preparing and taking impressions of the tooth or teeth involved. A temporary crown or bridge is then placed on your teeth. Meanwhile, the impressions are sent to the lab where a mold of your teeth is poured. The completed work is sent back to our office and after inspection and any necessary adjustments, the crown or dental bridge is cemented into place.
