A crown is a cap that is placed over a tooth and held in place by dental adhesive or cement. They are used for several reasons, including as a protective cover for badly decay or fractured teeth, permanent restoration for teeth with large fillings, and to correct minor problems in natural teeth, such as spacing or irregular shape.
They can be made from plastic, ceramic, metal alloys or even a combination of metal and ceramic to maximise strength and simulate the appearance of natural teeth.
The suitability for a crown is assessed before any preparatory work that may need to be carried out. We’ll be able to guide you on the various material choices and treatments – as well as address any other concerns you may have.
At your next appointment we’ll prepare any teeth that are to be crowned by reducing the tooth size (usually under local anesthetic), and then by taking an accurate mould. A laboratory will fabricate a crown from this mould.
The temporary crown that will have been placed on your tooth surface will be removed and cleaned thoroughly. We’ll test for appearance and bite, before finally cementing the crown in place with a special adhesive. You’ll then be the proud owner of a brand new, quality looking tooth!
Crowns are made of inert materials that do not deteriorate over time. However, the underlying tooth is still prone to decay and gum disease. Regular check-ups will enable your dentist to detect any problems with your crown and recommend necessary treatment.
Ceramic on the surface may chip or fracture. 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.
