Porcelain Crowns

porc crowns

A dental crown (cap) is a restoration that covers a tooth, restoring it to its normal size and shape, while strengthening and improving its appearance. A crown is necessary when a tooth is broken to the point where a filling will not be effective. A dental crown can be used for various reasons, including covering discolored or misshapen teeth, or restoring a broken tooth. It may also be used in conjunction with bridges and dental implants.

Benefits Of Porcelain Crowns

A major advantage of porcelain crowns is that they are created to look exactly like, or even better than, the teeth they are replacing. They are available in a wide variety of shades in order to perfectly match them to existing teeth.

Crown margins made with porcelain or zirconium prevents the irritation of the gingival tissue preventing gum recession and black lines found with metal based crowns.

They are also less likely to cause an allergic reaction. Extremely natural-looking, it is rarely noticeable that they have been used.

Other benefits of porcelain dental crowns may include:

  • Holding a cracked tooth together to prevent further damage
  • Covering and supporting a tooth with a large filling
  • Restoring a broken tooth

Crown procedure

  • Numbing the tooth to remove the decay in or around it.
  • Making an impression of your teeth in order to create a custom-made crown (usually takes one to two weeks).
  • After ensuring that the crown has the proper look and fit, the dentist bonds it into place.
  • Re-shaping the tooth to provide an ideal fit for the crown.
  • This process generally consists of a minimum of 2-3 visits over a three to four week period.
  • Making a temporary crown out of acrylic resin and fitting it onto the tooth during the interim period when the permanent custom-made crown is being created.
  • Applying the permanent crown (when received from the lab) by removing the temporary crown and fitting the permanent one onto the tooth.

Care Of Porcelain Crowns

Porcelain crowns are generally durable and long-lasting, and require no more care than natural teeth. In some cases, a patient who grinds her or his teeth during sleep may require a custom mouth guard to prevent excess pressure from causing a crown to crack.

A dentist should be consulted to see if a porcelain crown is an option for a particular condition.
