A crown is a permanent fixed restoration which replaced only one tooth. It is an ideal solution to rebuilding teeth that are damaged and weak or have very large fillings. A crown is sometimes referred to as cap.
To have a crown it requires the natural support of a stable root, this is determined by taking a radio graph before going ahead to asses bone support and the root of the tooth. The crown then sits over a small portion of your natural tooth for full support and coverage.nts.
There are lots of options for materials which can be used to construct the crown depending on need, cost and suitability. Some of the options are; porcelain bonded to non-precious metal, full porcelain-which are mainly used for front teeth only due to the strength and precious metals i.e.gold and palladium- these are the most hard wearing materials to use but due to the color are routinely only used for back teeth.
A crown should still be cleaned everyday and treated like a normal tooth, especially between the teeth, there are different products you can used and your dentist can advise you on what is the best to use.
Crowns are permanently cemented in place but can occasionally come loose due to multiple reasons, like biting hard on foods. Once cemented you will notice a difference in feel but after a few weeks you will become used to the difference. speech should not be affected, if it is then it means the crown needs adjusting.
To have a crown it requires more than one appointment and if needed a temporary crown can be made between appointments
