What is a crown?
A crown is a cap that is placed over a tooth and held in place by dental adhesive or cement. Crowns are used for several reasons:
- as a protective cover for badly decayed teeth or fractured teeth
- as a permanent restoration for teeth with large fillings
- to correct minor problems in natural teeth like spacing and irregular shape or severe discolouration.
What are crowns made from?
Crowns can be made from a variety of materials: plastic, ceramic or metal alloys. A combination of metal and ceramic is also possible to maximise strength and simulate the appearance of natural teeth.
