A crown is a cap that covers the tooth. Crowns are either made of porcelain and metal or pure porcelain, often called a metal free crown. Crowns provide protection and support to damaged or weakened teeth and provide a cosmetic improvement to the appearance of teeth. They are shaped and tinted to match the surrounding teeth for a natural appearance.
Porcelain-fused-to-metal crowns look similar to a person’s original tooth and are tinted and shaped to match the surrounding teeth. In some instances, patients may notice a gray line at the bottom of the tooth near the gum line where the metal in the crown is sometimes visible. All-porcelain crowns provide the most natural looking results but are slightly less strong than the porcelain fused to metal variety. This kind of crown is often used for the front teeth. Some patients prefer the metal and porcelain crowns because they are stronger and more durable, while other prefer the metal-free version for their appearance. Your dentist at 866-FIX-TEETH will discuss your options and help you to make the best choice to meet your individual needs.
Zirconia crowns serve the same purpose as porcelain and porcelain-fused-to-metal crowns but are made from zirconia, a biocompatible material. This option is growing in popularity because not only is it natural-looking with no metal fuse, zirconia crowns are very durable, require less tooth material to be removed, and are modifiable in size, shape, and color. Zirconia crowns are almost indestructible and will outlast porcelain crowns which also provide a natural appearance.
Crowns are used to protect and preserve teeth that are too badly damaged or decayed to benefit from a traditional filing. For example, crowns are often used following a root canal. Crowns are also used to cover teeth that are small or uneven to improve the appearance of a patient’s smile. Other reasons you might have a crown include:
Crowns are very easy to take care of, just like natural teeth. You brush and floss daily, and make regular visits to the dentist for professional cleanings and checkups. With proper care, crowns can last for 10 years or more.
