Dental Crowns

Dental Crowns or Caps

If your tooth is damaged but not lost, Your dentist may recommend a crown (also called a caps) to be used to cover the damaged part of your tooth. A crown protects your tooth from further damage. You may need a crown if:

  • You have a root canal
  • You have a large filling in a tooth
  • You have a broken tooth
  • Your tooth is badly stained, not the right shape or out of line

Crowns can be made of different kinds of metals, porcelain or porcelain fused to metal. They are strong and last for about 10 years, if you take good care of them. Brush and floss your crown, just like you clean your natural teeth. But crowns and replacement teeth may not be as strong as your natural teeth, so:

  • Do not bite down on hard objects.
  • Do not use your teeth to open or cut things.
  • Do not do these things with your natural teeth either.

What is a Dental Crown

A Dental Crown is a tooth-shaped cover or cap placed over a tooth that is badly damaged, decayed or discolored. A dental crown is made to look like your tooth.

Dental Crowns Before and AfterCrowns may be placed for several reasons, but generally the tooth has been extensively damaged by decay or breakage and filling material can't replace the missing tooth structure and make the tooth strong enough. A crown may hold together parts of a cracked tooth and can be used to hold a bridge in place. Crowns also are used for cosmetic purposes to cover misshapen or badly discolored teeth.

Crowns can be prefabricated or made in a laboratory. Prefabricated crowns are made of plastic or stainless steel and can be used as a temporary restoration until a permanent crown is manufactured. In some cases, prefabricated crowns can be used as a permanent restoration.

Crowns can be all metal, porcelain fused to metal (PFM), or all ceramic. Metals include gold alloy, other alloys (palladium) or a base-metal alloy (nickel or chromium). The all-metal or PFM crowns are stronger and are better choices for back teeth. PFM and all-ceramic crowns look just like normal teeth.

How Dental Crowns are Made

Here's how a Crown is Made;

  1. Your dentist may make a mold (or an impression) of your tooth to fit a temporary crown. It protects your tooth until the final, permanent crown is ready. Temporary crowns may not have the same shape and color as permanent ones.
  2. Your dentist gives you freezing (called a local anesthetic). He or she then files down your tooth to make room for the crown.
  3. Another mold (or impression) is taken of the filed-down tooth and nearby teeth. Then the temporary crown is placed over your tooth and you are sent on your way.
  4. This mold is sent to a dental lab, where your permanent crown is custom-made. The mold of your tooth is used to make a model. A filling (or restoration) that is the same size and shape as your tooth is built based on the model.
  5. On your next visit, your dentist takes off the temporary crown and puts on the permanent one. Then he or she checks to make sure the crown is the right fit, shape and color. If it is, your dentist cements the crown into place. Your tooth will look and work very much like a natural tooth.

These are the steps your dentist most often will follow in making a crown, but your tooth may need special care. You may need orthodontic treatment or gum treatment. It may take more than two visits to your dentist or your visits may last longer. Be sure to discuss your options with Dr Murray during your dental visit.
