Dental Crowns and Onlays


A dental crown or onlay, whether made from porcelain or metal, covers a structurally damaged tooth to restore integrity. Deep cavities, chips, or cracks may require a crown. In most cases, the dentist places an all-porcelain or porcelain-fused-to-metal crown on teeth so that a patient’s smile remains white and attractive. Back teeth must endure extreme pressure, so occasionally only a metal crown can withstand the biting forces.


Patients should expect two visits with the dentist for a full crown procedure. At the first appointment, the dentist will prepare the damaged tooth, take an impression, and place a temporary crown. A dental lab will fabricate a custom crown according to the impression and the doctor’s instructions. At a follow-up visit, the temporary crown is removed and the permanent crown secured. Some offices have the availability to fabricate crowns, inlays, and onlays in one visit.
