What do porcelain crowns consist of?

Porcelain crowns are fixed dental prostheses. They are used for replacing lost sections of teeth, such as those lost after large caries or injuries. They are custom-made to adapt to each patient's needs and they are attached to the teeth with a special adhesive, thanks to which it is almost impossible for the crown to become loose. Crowns offer excellent aesthetic and functional results. They may be used both in front teeth and in back teeth. Porcelain is a noble substance, bacteria are not likely to attach to it and it adapts to the teeth very well. The texture of porcelain crowns is the one that resembles most the tooth's enamel and its wide variety of shades allows for a perfect assimilation of the implant by the adjacent teeth. To make the crowns and the natural teeth look even, it is best to resort to a whitening treatment and to take the resulting shade as reference to create the shade of the porcelain crowns. Therefore, if the teeth loose their whiteness, both the natural teeth and the implants will be of the same shade.
