Dental crowns fit over your natural teeth after the tooth has been shaped to accept the crown. You may need a crown or crowns for the following reasons:
- Cracked tooth
- Large Cavity
- After root canal therapy
- Existing crown failure
- Worn fillings

When fillings begin to break down, they are no longer serving their original purpose and it is often a good idea to make a crown. A crown will provide protection for a damaged tooth.
The three most commonly recommended crowns are; porcelain, porcelain fused to metal, ceramic, and gold.
Gold Dental Restorations
Advantages: Historically, gold restorations last the longest. Gold is most similar to your natural tooth structure in hardness and the way it expands and contracts. Gold restorations do not tarnish and they do not wear down the other teeth they contact. They typically require less removal of the natural tooth. Gold is ideal for the back teeth where it is less visible in the smile line. Most dentists would agree that the best restoration material is gold.
Ceramic Crown Restorations
Advantages: These crowns are ideally suited to people who prefer something that has a natural appearance. They are made from a thinner material which results in a lighter crown. Porcelain crowns are kind to the natural gum tissue .
This type of crown is lifelike and pleasant to look at however, it is less durable than other types of crowns which means it is more prone to cracking or breaking. The refinement needed to produce these crowns makes them more difficult to fit. They require a high degree of expertise which increases their cost.
Porcelain Fused to Metal Restorations
Advantages: This crown is prepared with a metal shell then a porcelain veneer is fused onto the metal shell which gives the crown a natural looking appearance. This crown is most commonly preferred by the patient as it gives the restored tooth a natural look. The underlying metal fused with the porcelain provides stability and strength to the crown. It is the second strongest crown in comparison to the gold crown and has a better success rate.
Restoring teeth with porcelain fused to metal requires a large portion of the tooth structure to be removed. This type of crown can make the gums more vulnerable to gingival inflammation and wear down the neighboring teeth.
