Crowns or onlays (partial crowns) are a cosmetic restoration used to strengthen a tooth or improve its shape. Crowns/Onlays are most often used for teeth that are broken, worn, cracked, or partially destroyed by tooth decay.
Crowns/Onlays are cemented or bonded onto an existing tooth and fully cover the portion of your tooth above the gum line. In effect, the crown/onlay becomes your tooth's new outer surface. Crowns/Onlays can be made of porcelain, metal, or both. Porcelain crowns/Onlays (as above) are most often preferred because they mimic the translucency of natural teeth and are very strong. No metal margin (dark lines) can be seen with all porcelain restorations.
Crowns or onlays are needed when there is insufficient tooth strength remaining to hold a filling. Unlike fillings which apply the restorative material directly into your mouth, a crown is fabricated away from your mouth. Your crown/onlay is created in a lab from your unique tooth impression which allows a dental laboratory technician to examine all aspects of your bite and jaw movements. Your crown/onlay is then sculpted just for you so that your bite and jaw movements function normally once the crown/onlay is placed. The change can be both significant functional and esthetic improvement (see below).
