Sometimes a tooth becomes so severely damaged due to decay, cracked teeth or trauma that the area is too large to restore with a traditional filling. Such cases may call for a dental crown. One option to replacing missing teeth when teeth exist on either side of the space is a bridge.
A crown (or cap) is a covering that encases the entire tooth surface restoring it to its original shape and size. A crown protects and strengthens tooth structure that cannot be restored with fillings or other types of restorations.
Why would you need a crown?
A dental bridge is a ceramic structure, spanning the gap left by a missing or extracted tooth. A ceramic tooth (pontic) is fused between two or more porcelain crowns on either side of the missing tooth that serve as anchors.
