If you want a smile that's your crowning glory, you may need a crown to cover a tooth and restore it to its normal shape and size. 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 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.
If your dentist recommends a crown, it's probably to correct one of these conditions. Your dentist's primary concern, like yours, is helping you keep your teeth healthy and your smile bright -- literally, your crowning glory.
There are many types of crowns, however most used are: porcelain, metal and porcelain fused metal and zirconia. Porcelain fused metal crowns are stronger near the gum-line than porcelain crowns; however, today we can make them out of all porcelain, meaning that they can look very aesthetic and very natural. Zirconia crowns can also look beautiful and very natural. Zirconia is an extra tough ceramic material, and it can be made extra thin. They have no metal in them, and can be made translucent or opaque, depending on the demands of the situation. If they are bonded onto the teeth, and not just cemented with conventional dental cement, they won’t show a black line at the gum-line years later; the way porcelain fused to metal crowns may sometimes look.
