A tooth that has been severely damaged by decay or fracture may need a crown to preserve the tooth’s structural integrity. This is especially true if there are one or more cusps fractured or decayed, or the size the existing restoration is extensive and compromises the tooth strength. Sometimes when there is not enough of the natural tooth remaining to support a crown, a procedure called core build up is performed using composite to add back enough structure so the tooth can be crowned and preserved. Pins are frequently used in these situations to help anchor and retain the core to the tooth.

A crown is designed based on an impression or a scan of the tooth preparation and can be fabricated from ceramic, metal or gold. This usually involves a temporary crown phase while the custom crown is being made. Once ready, the permanent crown is then fitted and bonded into place. Crowns are an excellent treatment option when it comes to increasing the longevity of weak and extensively broken down teeth.
