Porcelain crowns are the ideal restoration to use on a tooth where a large filling has worn out, when a tooth is cracked, or to improve the appearance of a tooth. Porcelain crowns are used to protect a tooth that is too weak from decay to take a filling, or that has a large break or crack in it.
A crown restores a tooth to its normal shape and size while preserving and strengthening it. This helps protect the weak tooth from breakage, which could end up in the loss of the tooth.
Crowns are also used to attach dental bridges to the healthy teeth on each side of a missing tooth (or teeth). Crowns can be matched with your natural tooth color so the fact that you have had dental work is easily concealed. Porcelain crowns can also fix stained or misshapen teeth for a beautiful smile.
