A crown or cap is a tooth like covering placed over a carefully prepared existing tooth. Most crowns are made of porcelain, a stain resistant material that closely replicates the appearance and function of your natural teeth. Used to strengthen, restore or improve the appearance of your natural tooth a crown is placed on an individual tooth much like a thimble over your finger. Crowns are also used to support teeth when there is no longer sufficient tooth structure left to place a filling.
The tooth is prepared and an impression taken.
A crown is made from the impression and fitted to the tooth.
Over time the gum can recede away from the crown this is known as the crown margin.
The old crown can be removed and a new, deeper crown fitted to cover this area.
A large tooth may need to be root-treated and crowned.
If there is insufficient tooth left to secure the crown the root canals can be filled with fibre bridge material.
This is hardened with a bright light then placed back in position. The other root canals are filled in the same way.
As the Composite material is built up, a net is added to increase strength.
The net is pushed into the Composite and more material added.
