A crown (or cap) is a covering that encases the entire tooth surface restoring it to its original shape and size. A crown protects and strengthens tooth structure that cannot be restored with fillings or other types of restorations.
Although there are several types of crowns, all ceramic (tooth colored crown) are the most popular, because they resemble your natural teeth. They are highly durable and will last many years, but like most dental restorations, they may eventually need to be replaced. All ceramic crowns are made to match the shape, size, and color or your teeth giving you a natural, long-lasting beautiful smile.
Reasons for crowns:
What does getting an all ceramic crown involve?
the tooth is numb, your dentist will remove any decay and/or old
restorations as necessary. An optical 3D image is then acquired with a
small camera, directly in your mouth. The restoration is created on
the screen using the image data. Diamond coated instruments mill a
ceramic block to reproduce the design. This is accomplished during a
single appointment using Computer Aided Design/Computer Aided
Manufacture (CAD/CAM). After polishing, the new restoration fits
precisely. A unique light hardens the bonding material, uniting
porcelain and tooth. Polishing or glazing the finished crown ensures a
pleasantly smooth and natural feel.
