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.
There are several types of crowns, the main ones being porcelain fused to metal crowns and all ceramic (porcelain) crowns. Metal adds addtional strength to overlying porcelain and is important in areas of the mouth subjected to heavy biting or grinding forces. All ceramic crowns are used in areas where esthetics are highly desireable. Their translucence makes them the dental restoration that is most able to resemble your natural teeth. They are highly durable and will last many years.

What does getting a crown involve?
A crown procedure usually requires two appointments. Your first appointment will include taking several highly accurate molds (or impressions) that will be used to create your custom crown. A mold will also be used to create a temporary crown which will stay on your tooth for approximately two weeks until your new crown is fabricated by a dental laboratory.
While the tooth is numb, the dentist will prepare the tooth by removing any decay and shaping the surface to properly fit the crown. Once these details are accomplished, your temporary crown will be placed with temporary cement and your bite will be checked to ensure you are biting properly.
At your second appointment your temporary crown will be removed, the tooth will be cleaned, and your new crown will be carefully placed to ensure the spacing and bite are accurate.
You will be given care instructions and encouraged to have regular dental visits to check your new crown.
