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 and root canal work
- 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. They can be made from plastic, ceramic or metal alloys. A combination of metal and ceramic is also possible to maximise strength and simulate the appearance of natural teeth.
How are crowns made?
After careful preparation and impressions by the dentist, a very skilled dental technician hand-makes your crowns with dental porcelains by compacting dry porcelain before firing this in a furnace to provide the dense, and aesthetic porcelain crown which is fitted with dental glues.
How long do crowns last and how do I care for them?
Crowns are made of inert materials that do not deteriorate over time. However, the underlying tooth is still prone to decay and gum disease. Ceramic on the surface may chip or fracture so avoid chewing excessively-hard substances like ice or bones.
Daily brushing and flossing are essential for maintaining good oral health as well as keeping the crown trouble-free. The most vulnerable portion of the crown is the margin or the junction between tooth and crown.
With careful attention, crowns should last in excess of 10 years. Regular check-ups will enable your dentist to detect any problems with your crown and recommend necessary treatment.
