Porcelain Crowns

Reliable, Fast and Beautiful

According to the ADA, crowns  are “An artificial replacement that restores missing tooth structure by surrounding the remaining coronal tooth structure, or is placed on a dental implant. It is made of metal, ceramic or polymer materials or a combination of such materials. It is retained by luting cement or mechanical means”

When to use a dental crown?

In simple terms, a crown is a “cap” that can be used to strengthen a broken down tooth, improve the shape & contour of a tooth & enhance the color of a tooth. A dental crown can be used for a variety of purposes including but not limited to the following:

  1. Protect a Fractured Tooth
  2. Cover Dental Implants
  3. Whiten a Tooth
  4. Protect a Root Canal Treated Tooth
  5. Provide an Attachment for a Bridge or Fixed Partial Denture

Dental Crowns Vs. Dental Veneers

Bruxer

Those that are caught clenching or grinding their teeth throughout the day and at night are typically not indicated for veneers. Recall that veneers involve a thin layer of porcelain & a patient who grinds is more likely to fracture veneer then a crown.

High Carious Activity

Those that have a lot of decay & cavities that are typically indicated for crowns over veneers. Veneers often require minimal preparation. If the preparation becomes larger, a crown is better indicated.

Eroded Teeth

Veneers require a layer of enamel in order to properly bond to your teeth. If there is a lack of adequate enamel a veneer will be unable to achieve a strong bond to the tooth. Some teeth have more enamel then others which will determine whether a crown or veneer is placed.

Malpositioned Teeth

If the teeth are rotated in an unfavorable manner, the placement of crowns is typically better indicated then veneers. Placement of veneers can be done when minimal tooth repositioning needs to be accomplished.

Occlusion

If the dentist needs to correct how your teeth come together, crowns provide more adequate treatment then veneers. Occlusion should be stable for if placing a veneer.

Dental Crown Materials

According to the ADA, crowns can be made of a variety of materials. I have listed the variety of materials below as well as some of the benefits of each material:

  1. All Porcelain Crowns – Porcelain crowns truly mimic the natural tooth color & is highly resistant to wear. The strength depends on the quality of the bond to the underlying tooth & it may require a more aggressive tooth preparation in order to allow for an adequate bulk of porcelain. Porcelain crowns do have the ability to wear away the opposing dentition at a faster rate then non – porcelain materials. Porcelain crowns fracture more easily than some other materials.
  2. Porcelain Fused to Metal Crowns – Porcelain is fused to an underlying metal layer & this type of dental crown is very strong & durable. Further, this type of crown is resistant to leakage. This crown can closely mimic natural tooth structure but the metal may limit the translucency.  A thin layer of metal can sometimes be seen at the gingival edge of your teeth. Further, porcelain may fracture from the metal base.
  3. Gold Crowns  – Gold Crowns require minimal preparation, have high strength & are resistant to fracture. Gold crowns provide excellent durability & minimal wear on the contralateral tooth. However, gold crowns are not as aesthetic as other dental crowns. Thus, gold crowns are typically placed on the back teeth away from the natural view. Gold crowns conducts hot & cold temperatures rather easily.
