Onlays & Crowns Small cavities can be fixed with fillings because there is still plenty of healthy tooth structure. Thanks to modern adhesive technology, moderate to large cavities can be treated with onlays. However, the very large cavities and teeth with root canal treatments need to be fixed with crowns. Without a crown to strengthen it, the tooth can break. A crown strengthens a damaged tooth by covering and protecting it. |

All Porcelain Crowns
Tooth-colored crowns used to be made of porcelain and metal. To have enough strength to withstand biting forces, porcelain crowns used to always be built upon a metal core. The dark metal inside the porcelain/metal crown causes a dark blue line to show at the edge of the crown. Also, the metal under the porcelain would not allow the light to illuminate through causing the porcelain to stand out even though the shade may have been close.
New breakthroughs in adhesives and stronger porcelain materials now make it possible to make crowns entirely out of porcelain, which then can be bonded to the teeth. All-porcelain crowns maintain a translucency that makes them hard to tell from natural teeth. Without metal, the problem of the dark blue line at the edge of the gums is eliminated. They also allow the light to shine through just like natural teeth. This allows us to place the edge of the crown above the gumline, which is healthier for your tooth and gums.
When you want to improve your smile, all-porcelain crowns are a beautiful and natural-looking choice!
