Crowns cover your existing teeth, providing added strength. When are crowns needed? After a root canal, your tooth is left without a blood supply, making it brittle. Placing a crown will prevent breakage of the remaining tooth. Crowns are also often prescribed for teeth that have broken or have large existing fillings. The common term for a crown is “cap”.
Crowns come in several styles. Porcelain fused to metal is the most common type a crown and is referred to as a PFM. All gold crowns, called full cast gold, are often used on back teeth. An all porcelain crown is the best crown for a natural appearance, as PFM will have a gray line at the gumline from the underlying metal.
A crown requires two dental visits. The first is a preparation with impressions, shaping, and placing a temporary. The impressions are then sent to our on-site dental lab, where the process takes three weeks. The great thing about our on-site dental lab is if the shade or fit are not quite right at your seat appointment, instead of coming back for an additional appointment, the lab technician will usually be able to perfect your crown that day.
