Crowns

Crowns are made of porcelain, porcelain and metal, or entirely out of metal. They are best used in cases where teeth are broken down and need structural support and protection. They might also be appropriate if gaps are extremely wide. If your teeth are intact and you merely want to close spaces, bonding, veneers, or orthodontics may also be options for you.

Advantages:

Crowns can repair structural damage, are very strong, and can be made from several different materials, including Cerec crowns.

Disadvantages:

Crowns require a relatively large amount of tooth reduction, they may be less natural looking than veneers or bonding and may show a dark blue line where it meets the gumline if your gums recede. Porcelain crowns may wear down on opposing teeth.
