Crowns
A crown is an artificial restoration that fits over the remaining part of a prepared tooth, making it strong and giving it the shape of a natural tooth.
​
A crown is sometimes known as a ‘cap’. Crowns are an ideal restoration for teeth that have been broken or have been weakened by decay or a very large filling. They can be made of porcelain or gold or a combination of these materials.
Tooth location, the position of the gum tissue, the amount of tooth that shows in the smile, the colour and shade of the tooth, and the function of the tooth are all taken into consideration when choosing which material to use.
A dental crown could be used for several other reasons, for instance:
​​
-
you may have discoloured fillings and would like to improve the appearance of the tooth
-
you may have had a root filling which will need a crown to protect it
-
it may help hold a bridge or denture firmly in place.
Having a crown fitted may require two or three dental visits. At the first appointment, the tooth to be crowned will be numbed and reduced in size to accommodate the crown, and then a mould of your tooth will be taken for the laboratory to use in the manufacture of the crown. A temporary crown will be placed over the tooth until the custom (final) crown is available.
Crowns are permanent fixtures, but they can occasionally come loose and need to be replaced. Caring for a crown requires proper dental and gum care as instructed by a dentist or hygienist.​
