Metal Crowns
At our clinic we rarely use metal crowns but sometimes occasion may arise that demand use of metal crowns. Although their metallic color makes them a poor choice for highly visible teeth, dental crowns made of metal can be an ideal option for repairing decayed or damaged back teeth. They are extremely durable and can be applied with less removal of the natural tooth than all porcelain or ceramic crowns. Metal crowns may consist of various materials, including gold alloy, palladium, nickel alloy, or chromium alloy. In the past gold crowns used to be a fashion for some people who prefer to use them as cosmetic appeal though it is not the case now days.

All Ceramic Crowns
All ceramic crowns may be made of porcelain, or dental ceramic materials. They create an extremely natural-looking appearance and are typically used on front teeth. The tooth-colored ceramic material is translucent, like the enamel of your natural teeth, and size and shade can be carefully matched to complement the rest of your smile. However, ceramic dental crowns are not as resilient as metal crowns and do not function as well on back teeth, which sustain a lot of pressure from biting and chewing.

Porcelain Fused to Metal - PFM Crowns
Because of the high pressure of chewing dental crowns made of porcelain fused to metal are stronger than all-ceramic versions and more aesthetically pleasing than those made of metal. With new development in dental ceramics ceramic fused to metal are becoming popular even for cosmetic works on anterior teeth.
