Porcelain Crowns
Crowns or porcelain covers protect the whole tooth, simulating its natural anatomy. They can be made either with porcelain only, or with a core from some other material to give it more strength, like metals or more recently zirconium.
Crowns are made with a material so resistant that may even last for more than 50 years. However, due to the natural wear induced by chewing, sometimes they lose their shape or become dull. In this cases, if the patient wishes so, the crown is extracted a new one is put into place. |
