A crown is a tooth-shaped “cap” restoration that covers a tooth in order to strengthen it as well as restore it to its normal shape and size. A crown may be placed to protect a weak tooth from breaking, cover and support a tooth with a large filling and minimal tooth structure left, attach a bridge in place, protect weak teeth from fracturing, restore fractured teeth, cover a dental implant, or provide strength to a weakened root-canaled tooth.
A fixed bridge, usually made of zirconia or gold, is used to bridge the gap created by one or more missing teeth. A bridge helps to restore your smile, create a normal bite, restore the ability to properly chew and speak, prevent stress on the dental arch, and prevent the drifting and tilting of adjacent teeth. Bridges are attached to the teeth on either side of the missing tooth/teeth. It involves preparing the adjacent teeth for crowns, as the false tooth is then attached to those crowns. Depending on your specific case, implants are sometimes a more ideal option to consider versus a bridge.
