When a tooth is fractured, has a large, old filling, or is severely damaged by decay, the placement of a crown (or cap) may be recommended. Crowns strengthen and protect the remaining tooth structure and can improve the appearance of your smile. Types of crowns include the full porcelain crown, the porcelain-fused-to-metal crown and the all-metal crown.

Fitting a crown requires at least two visits to the dentist's office.

	Decay is removed and the tooth is shaped to accept a crown.
An impression of this section of the mouth is taken.
	A temporary (or transitional) crown of plastic or metal is formed and fitted to the reshaped tooth.
During the next visit (usually a week or two later), the temporary crown is removed and the permanent crown is placed, adjusted and cemented into place.

Bridges

Few incidents have greater impact on dental health and personal appearance than tooth loss. When one or more teeth are missing, the remaining teeth can drift out of position, which can lead to a change in the bite, the loss of additional teeth, decay and gum disease.

When tooth loss occurs, your dentist may recommend the placement of a bridge. A bridge is one or more replacement teeth anchored by one or more crowns on each side.

	The teeth on each side of the space are prepared and shaped to receive crowns. An impression of the area is made.
A temporary (or transitional) bridge may be formed and fitted in the area.
	During the next visit (usually a week or two later), the temporary bridge is removed and the permanent fixed bridge is placed, adjusted and cemented into place
