Crown and Bridge

A crown is a covers or "caps" for a tooth to restore it to its normal shape and size thus    strengthening and improving the appearance of a tooth. Prosthetic crowns are made of metal,    porcelain fused to metal substrates, or new all-white restorative materials.

Crowns are necessary when a tooth is generally broken down and fillings won't solve the    problem. If a tooth is cracked, a crown holds the tooth together to seal the cracks so the    damage doesn't get worse. Crowns are also used to support a large filling when there isn't    enough of the tooth remaining, attach a bridge, protect weak teeth from fracturing, restore    fractured teeth,cover badly shaped or discolored teeth or protect a root-canal filled tooth with compromised strength.
