The second and most important is to act as protection. It serves as a shield against bacteria, defending it against infection and fracture. It covers the entire tooth acting as a seal thereby preventing bacteria from penetrating through. This is especially important when the tooth has previously undergone a root canal. As a result of this intervention, the tooth can become fragile and requires additional protection to prevent it from breaking or becoming re-infected. Crowns are used to strengthen the tooth when a large amount of tooth structure has been lost due to decay. In this case, fillings won’t be able to withstand the force of mastication exerted and crowns will be the treatment of choice to prevent fracture. Older crowns are supported by a metal and tend to show a thin silver lining around the gums overtime, while newer crowns are composed of a lithium disilicate ceramic or zirconia for optimum esthetics and strength. They can last decades if maintained well and range in cost from $700-$1,500.

Christie Brinkley is as beautiful today as she was when she appeared on her very first Sports Illustrated cover. Her secret? A great smile. “Share your smile with the world,” she says. “It’s a symbol of friendship and peace.”
