Crowns
Dental crowns are tooth-shaped coverings placed over teeth that are cracked, badly decayed, damaged or otherwise misshapen. The crown not only strengthens and protects the tooth, it restores its natural size and shape. There are several crown types to choose from, depending on the location of the tooth and your aesthetic preferences.
Traditional metal (i.e., gold) crowns are appropriate when appearance is not an important factor, such as for molars which are not highly visible when you smile. For cosmetic reasons, however (such as with front teeth), porcelain crowns are considered the most aesthetically pleasing, as they are so easily matched in color and appearance to the surrounding teeth. There are several different kinds of porcelain crowns.
All-porcelain crowns have the nicest appearance. This crown can be made from pure ceramic or a reinforced composite resin, and is almost indistinguishable from natural teeth. The new bonding technology involved provides an exceptionally tenacious seal to your tooth.
Bridges
A bridge (fixed partial denture) is a device, which fills the gap where teeth are absent. Fixed bridges are bonded into place and can only be removed by a dental professional. Fixed bridges offer more stability than their removable counterparts (partial dentures).
