Large failing fillings, tooth decay, grinding your teeth can all be contributing factors in the wearing down, cracking or breakage of your teeth. When this situation occurs, it is no longer feasible to place more filling material. A crown can make your tooth stronger and improve its appearance.
It can cover and support a tooth (with a large filling) when there isn’t enough tooth left. It can be used to attach a bridge, protect a weak tooth from breaking or restore one that’s developed a crack. A crown is also a good way to cover teeth that are discolored or badly shaped. It’s also used to cover a dental implant.
