What are crowns?
Crowns are prosthetic devices used to repair damaged teeth. A crown is effectively a new surface for a broken, misshapen, weakened or heavily filled tooth.
When are crowns used?
Crowns may be used to:
– Cover a heavily filled tooth
– Protect a weak tooth
– Restore a fractured tooth
– Make an anchor for attaching a bridge
– Cover a discoloured or poorly shaped tooth
– Cover a badly aligned tooth
What is a crown made from?
Crowns are usually made from porcelain or ceramic, which can be matched to the colour of natural teeth. Other materials, including gold and metal alloys are sometimes used.
What is the procedure for fitting a crown?
– The tooth to be crowned will be cut and filed to make room for the crown.
– The dentist will make a mould of what remains of the tooth and the adjacent teeth
– A dental technician will use the mould to make the crown
– A temporary crown made of metal or plastic may be provided until the crown is ready
– The dentist will fit the crown, trying it for size and comfort and making any necessary adjustments before cementing it in place
Advantages of crowns
– Crowns look and feel like natural teeth
– Crowns can be matched in colour and shape to your own teeth
– Crowns can last for many years if looked after and depending on the strength of the tooth underneath
