All porcelain crowns maintain a translucency that makes them hard to distinguish from natural teeth. Without the metal, the problem of a dark line at the edge of the gums is eliminated.
The new technological breakthrough in the cements and stronger porcelain materials make it possible to create longer lasting crowns.
Crowns are made from a variety of materials that strengthen and protect the tooth structure. There are three types of crowns: a full-porcelain crown, a porcelain fused-to-metal crown and the all-metal crown. Your dentist will discuss and help you decide which type of crown is suitable for you. Crowns are suggested for the following reasons:
- Severe damage from decay
- A filled tooth can no longer support the filling
- Root Canal – after a root canal, the tooth becomes brittle and requires the protection of a crown
- Bridges – when teeth are replaced by a bridge, the adjacent teeth need crowns in order to support the bridge.
A crown is placed to prevent a tooth from breaking. As we get older, we are more prone to breaking teeth. If a tooth has a large filling, it is more prone to cracking or breaking. A crown, especially if it has metal in it, will help protect a tooth against breaking. Some people can break back teeth even if they have small fillings or no fillings in the tooth—their occlusion is that powerful.
