Crowns are designed to fit precisely over the remaining tooth structure prepared by a dentist. Crowns assist with additional strength and providing a natural appearance when a tooth has become weak and suffering from structural damage due to a variety of reasons e.g. decay, root canal therapy, damage such as cracking or fracturing of the tooth etc
A crown can be made from porcelain, alloy, gold or a combination of these materials.. This will usually be determined by a dentist or discussed between the dentist and technician.
A dentist will select a colour match or refer to our lab for a shade consultation for more complex colour.
Porcelain Crowns have been known to last for decades with proper care.

A bridge is a permanent fixed appliance used to replace missing teeth.
There are various different types of bridges. A bridge can be made from porcelain, alloy, gold or a combination of these materials.
A traditional bridge is made up of two crowns on either side of a missing tooth or teeth. The two anchoring crowns are called abutment teeth. The tooth or teeth in between are called pontics and the pontics are used to fill in the area of the missing tooth or teeth.
Please see below diagram of prepared abutment teeth and a traditional bridge
Unlike a traditional bridge a cantilever bridge supports a pontic from one end. It is built using an abutment crown on one side of the missing tooth supporting a pontic to fill in the space from that missing tooth.

Another option is a maryland bridge. A Maryland bridge consists of a pontic tooth supported by metal framework and metal wings that are bonded to the existing tooth or teeth.
