Porcelain Crowns and Bridges A tooth colored crown or bridge can be made of both porcelain and metal. With new technology it can also be made of all porcelain. All porcelain crowns and bridges maintain a translucency that makes them hard to tell from natural teeth. Due to the new porcelain crowns and bridges, the problem with dark lines from metal crowns and bridges is eliminated. As an alternative to an implant, a bridge can be fabricated to replace a missing tooth. The porcelain allows for a more natural looking tooth. Previous Page
