Crowns cover and protect teeth
A crown can make your tooth stronger and improve its appearance.
It covers and supports 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 is already broken. A crown is a good way to cover teeth that are discolored or badly shaped. It's also used to cover a dental implant.
