What is a crown?
A crown (“cap”) is a tooth-shaped dental restoration that is used to cap or embed a completely damaged tooth or dental implant. Also called “dental caps” and “ceramic jackets,” they can be made from a variety of materials and are permanently bonded to their dental cement base, avoiding the need for tooth extractions, bridges, partials or dentures. Cannot be used for full mouth restorations.
Why are teeth crowned?

Reducing the pain you are experiencing as a result of cracked teeth syndrome;
types of crowns
stainless steel
Prefab crowns that are used on permanent teeth primarily as a temporary measure, to protect or fill teeth. Most of these crowns are used in pediatric dentistry because they do not require multiple visits to implement, and are therefore more cost-effective than custom crowns and the dental care needed to protect teeth without a crown.
metal
Crowns include gold or other alloys (for example, palladium), or a base metal alloy (for example, nickel or chromium). Metal crowns withstand biting and chewing forces well and may last the longest in terms of wear. Also, metal crowns rarely chip or break. The metallic color is the main drawback. Metal crowns are a good choice for out-of-sight molars.
porcelain
This type of crown can be color-matched to your adjacent teeth (unlike metal crowns). The ceramic part of the crown can also chip or break off. This type of all-porcelain crowns is similar to regular teeth. However, sometimes the mineral that underlies the crown porcelain can appear as a dark line, especially at the gum line and more so if the gums have receded. These crowns can be a good choice for the front or back teeth.
