Dental crowns AKA caps are made of medical grade porcelain, placed on the top of a tooth to restore tooth’s function and appearance. This usually follows root canal treatments, fractures, heavy decay, missing tooth structure and for aesthetic reasons.
Research shows that capping a tooth after a root canal treatment may increase the life of the tooth and decrease the risk of fracture.
Crowns are also used to attach bridges, cover implants, prevent a cracked tooth from becoming worse, or an existing filling is in jeopardy of becoming loose or dislocated. Crowns can be used to heavily stained teeth.
The procedure is simple. A space is created to accommodate the cap by reducing 1 mm of the tooth structure. An impression (replica) of the tooth is taken. After it being processed in the lab, a crown is fitted on the tooth and cemented with a strong cement.
