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 ideal for teeth that have been broken, or have been weakened by decay or a very large filling. A crown looks and functions as a natural tooth would, and so it is able to restore the appearance of a smile and oral health. A dental crown could be used to improve the appearance of a tooth that has been discoloured. If you have had a root canal filling it may need a crown to protect it from further decay or infection.

Crowns can be made of porcelain or gold or a combination of these materials. When cemented into place, they fully encase the entire visible portion of a tooth that lies at and above the gum line. Daily brushing and flossing are essential for maintaining good oral health as well as keeping the crown trouble free. The most vulnerable portion of the crown is the junction between tooth and crown

The Procedure
Your gums are numbed with a local anesthetic, Next, the tooth receiving the crown is filed down along the chewing surface and sides to make room for the crown,  Impressions of your teeth are made and sent to a dental lab where the crown is manufactured. The crown is returned in 1 – 2 weeks,  During the first visit, your dentist will make a temporary crown to cover and protect the prepared tooth while the crown is being made,  On the second visit the crown is temporarily placed on your teeth and is repeatedly removed and trimmed as needed to achieve the proper fit,  A special cement is applied to the crown and then a special light beam is applied causing it to harden quickly, Finally, any excess cement is removed and your bite is evaluated. Slight adjustments in the crown are made as necessary.
