Dental Crowns

Is a restoration of tooth form commonly called a “cap”.  It covers the entire tooth down to or near the gum line.  It can be made of several materials depending on the mechanical demands.  For instance a crown on a front tooth will be made of a ceramic based material.  A crown for a 12-year (second) molar tooth will often be metallic (yellow gold or white gold)

 

Crowns for teeth between the front and the very back teeth may have a gold foundation that is veneered with ceramic.  They may also be made of  ceramics of varying strength.  The strongest ceramics used for crowns are the zirconia variants as well as lithium disilicate.
