When the size of a “filling” exceeds a certain proportion of the tooth, it must be replaced with a “crown” also called a “Cap”. Crowns reflect light with a natural healthy glow. They strengthen teeth and improve a tooth’s appearance especially after the root canal treatment. You should consider a crown if you are looking to protect damaged, cracked or worn teeth. It covers your existing tooth, protecting the entire surface from any further decay or erosion.

Crowns can be made from a wide range of materials. These include cercon (zirconium oxide, one of the hardest substances), all porcelain, gold or a combination of metals, which have been fused to a porcelain shell. While metal porcelain crown has a metal base and porcelain outside, the all porcelain crowns are metal-free translucent ceramic crown, and remain unnoticeable even for an expert eye from 5-10 cm.

Cercon crowns are the strongest of all, up to five times stronger than all-porcelain crowns as well as natural looking. Zirconia is a ceramic material that has been used to create crowns in cosmetic dentistry to give crowns and bridges a whiter brighter more translucent quality.
