A crown is sometimes known as a ‘cap’. 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. Crowns are an ideal restoration for teeth that have been broken, or have been weakened by decay or a very large filling. A bonded crown is a crown with a metal base and porcelain coating.
When is a bonded crown recommended?
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 what is left of the tooth.
It may help hold a bridge or denture firmly in place.
How Long Do Bonded Dental Crowns Last?
On average, dental crowns last between five and 15 years. The life span of a crown depends on the amount of “wear and tear” the crown is exposed to, how well you follow good oral hygiene practices, and your personal mouth-related habits (you should avoid such habits as grinding or clenching your teeth, chewing ice, biting fingernails, and using your teeth to open packaging)./p>
It is also important that the tooth be in a healthy state to ensure its longevity. In all cases, your dentist will evaluate the gums and supporting bone structure to ensure these supporting tissues are healthy. This protects the tooth and minimizes the potential for eventual gum recession that exposes the crown margin.
