CROWN: A crown is a restoration that covers, or “caps,” a tooth to restore it to its normal shape and size, strengthening and improving the appearance of a tooth.
BRIDGE: A bridge is a dental appliance that replaces one or more natural missing teeth,thereby “bridging” the space between two teeth.
If you’re missing a tooth or more, you may find that there are other things you miss. You may miss your natural smile. Naturally, the effect of tooth loss varies from person to person and depends on what exactly has been lost. The root anchors the tooth in your jawbone, providing stable support for the crown. Without the root, the bone around the lost tooth may gradually recede, remaining teeth may shift and chewing may become more difficult with time. If you’re interested in replacing your entire tooth,your option is dental implant or bridge restoration.

When the gum recesses,full-ceramic crowns protect their esthetic appearance,but metal-porcelain crowns create a bad image in the region.Allergic reactions dont occur in full ceramic crowns.
