Teeth that have been broken or weakened by tooth decay or a very large filling can be restored by a Crown. 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’.
Types of Crowns
Crowns can be made from a variety of different materials including Porcelain, All-ceramic, Glass and Gold-alloy crowns or metal-free materials. The choice of material will depend on each individual patient and the type of tooth in question. Where teeth are discoloured physiologically or by other means, this can be enhanced and lightened through various shades by a technique known as bleaching or teeth whitening.
We now use minimally invasive techniques which involve less tooth preparation and less tooth destruction to provide the crown, however, each tooth and patient is different so there may be degrees of preparation.
