A cosmetic dental crown is a restoration that covers – or “caps” – a tooth to restore it to its normal shape and size. Its purpose is to strengthen or improve the tooth and its appearance as well. A crown is placed for a number of reasons:
to support a large filling when there isn’t enough tooth structure remaining
to attach a bridge
to protect weak teeth from fracturing (or a fractured tooth from breaking further)
to cover badly shaped or discolored teeth
to cover a dental implant
