Crowns are restorations that cover teeth that are no longer structurally sound. Root canals, lost fillings, decay below a filling, chipping and cracking of the enamel are things that may lead to large scale defects in a tooths surface. When the entire surface of the tooth is a problem, but the root system is intact, a cap might be appropriate for you. Preparing a tooth for a crown usually requires two visits – at the first visit the tooth is examined for any gross decay which is removed and the tooth is properly restored before it is prepared to receive the crown, if the tooth had already received root canal treatment then this step should have been done before preparing for the crown. After anesthetizing the tooth and gum tissue around the tooth receiving the crown is filed down along the chewing surface and sides to make room for the crown. An impression is taken for the tooth and send to the laboratory to fabricate the cap. The crown is usually ready in three days during which your tooth will be restored with a temporary crown. Receiving the permanent dental crown - at your second visit, your dentist will remove your temporary crown and check the fit and color of the permanent crown. If everything is acceptable, a local anesthetic will be used to numb the tooth and the new crown is permanently cemented in place.

Based on the same idea of crowns, bridges are used to restore a missing tooth when a dental implant cannot be used for any reason. It utilizes the two teeth on either side of the gap (called abutment teeth ) which hold a false tooth in- between. Why should I restore a missing tooth? Teeth help to support our cheeks and lips. When teeth are lost and not replaced the cheeks loose their support and become sunk-in giving an older appearance. Also when a tooth is lost and not replaced the neighboring teeth start to move in place. These results in loss of chewing efficiency and predispose to gum and periodontal problems.
