Crowns

Dental crowns are a powerful cosmetic and restorative tool for treating teeth that have been significantly damaged,  or decayed, Dental crowns fit perfectly over your tooth, covering it from the top to below the gum line.  The crown is bonded to your tooth. A crown is recommended in the following situations:

  • Root canal restoration (Endodontic procedure)
  • Tooth weakened by numerous amalgam fillings
  • Cusp fracture of a tooth
  • Cosmetic restoration of a tooth unsuited for veneering
  • Neuromuscular Full Mouth Reconstructions will sometimes feature crowns to permanently  correct bite issues.

In all these cases, your dental crown will fit completely over your tooth, making it more attractive, protecting it against further damage and decay, and providing it with fully functional chewing surfaces.

Crown Types
There are three types of crowns available for use in dental restorations today:

All-metal crowns are primarily functional restorations.  Their only functional lack is that they conduct heat very well, and can sometimes make a tooth sensitive to temperature extremes, although this is generally not a problem in root canal procedures where the root of the tooth has been removed. Gold is an exceptional material for restoring back teeth due to its inherent qualities. It is extremely durable especially when subjected to the stresses and strains of chewing. The needed thickness to achieve this durability is relatively low, meaning less tooth structure is removed in preparing teeth for gold crowns. The soft, pliable nature of gold allows for a very precise fit and is very gentle to the opposing teeth resulting in a very long lasting choice of restoration

All-porcelain crowns are both functional and aesthetic restorations.  Porcelain crowns can, in many cases, blend in completely in your mouth, making them undetectable.  All-porcelain crowns can also be very convenient.  With our new CEREC  machine, all-porcelain restorations can be crafted while you wait, so there is no need to take an impression of your teeth, then wait while the restoration is made..  Instead, the CEREC machine uses a CAD/CAM system to manufacture the all-porcelain crown within minutes.  To learn more about this exciting technology and how it has revolutionized the process of making dental restorations, see our CEREC link.

Porcelain fused to metal crowns are both functional and aesthetic restorations. A porcelain-fused-to-metal crown (PFM) could be considered to be a hybrid of the other types of crowns, in the sense that it is composed of two different types of materials. One is a metal alloy that is used to create that portion of the crown that fits directly on the tooth. The other is porcelain. The porcelain forms the tooth-shaped aspect of the crown and gives the crown a white tooth-like coloration. The PFM is often used when destructive night grinding is a problem or when long span bridges are needed.
