Crowns are ideal restoration for teeth that have been broken or have been weakened by decay or a very large filling. A crown could be used for a number of other reasons:
- 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 what is left of the tooth.
- it may help hold a bridge or denture firmly in place.
Crowns can be made of Metal/Porcelain, Zirconium/Porcelain or pressed porcelain which are strong and most natural materials. We will prepare the tooth to the ideal shape, take an impression (mould) of the prepared tooth & give to the dental technician along with an appropriate shade and other information needed. A temporary will be made so that ( mostly for aesthetic). The final restoration is back usually in one week time & will be fitted after you and your dentist are happy with the fit and appearance of it.
Types of Crowns
The tooth is prepared and a crown is then made and fitted to the tooth.
The crown which has a metal base and porcelain coating is created.
The crown is made from natural looking and biocompatible porceline.
Over time the gum can recede away from the crown … … this is known as the crown margin. The old crown can be removed … … and a new, deeper crown fitted to cover this area. – See more at: http://www.angelsmile.co.uk/crown-margin/#sthash.e35sPYeA.dpuf
