A crown completely covers the damaged tooth above the gum line and so protects it. The colour is matched to that of your own teeth and, as crowns are very strong, they can look and feel exactly like natural teeth.
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. A crown could be used for a number of 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.
