Porcelain Crowns

What is a crown?

A crown is a cover or “cap” your dentist can put on a tooth. The crown restores the tooth to its normal shape, size and function. The purpose of a crown is to make the tooth stronger or improve the way it looks.

Why do I need a crown?

You may need a crown if you:

●       have a cavity that is too large for a filling

●       have a missing tooth and need a bridge

●       need to cover a dental implant

●       have a tooth that is cracked, worn down otherwise weakened

●       have had root canal treatment—the crown will protect the restored tooth

●       want to cover a discolored or badly shaped tooth and improve your smile!

How is a crown placed?

Several steps are involved, and two dental visits are generally needed to complete the treatment.

●       The dentist prepares the tooth by removing its outer portion so the crown will fit. Any decay is also removed. If additionaltooth structure is needed to support the crown, the dentist may build up the core of the tooth.

●       An impression is made to provide an exact model for the crown.

●       You will get a temporary crown while you wait for the permanent crown to be ready—usually less than two weeks. While you have the temporary crown, this tooth may be sensitive to hot and cold. Also, avoid chewing gum or sticky foods during this time.

●       The dentist or a laboratory technician then uses the model to help make the crown.

●       When the new crown is ready, the dentist places it in your mouth and makes the necessary adjustments. When you and your dentist are satisfied with how it looks and feels, the crown is cemented in place.

Types of Crowns

Complete Ceramic Emax

Emax crown is a type of all-ceramic crown which is preferred for its longer lasting aesthetic qualities. It has an appealing color which is combined with extra strength and durability and is made from a single block of lithium disilicate ceramic that has been harvested for its toughness and durability.

This is a crown that is considered to be the best match with your own natural teeth. There is no metal alloy base with this crown which means no unsightly looking gray line around the gum line. They are strong, long lasting and unlikely to crack or fracture as compared to many other types of crowns.

They are two ways to do emax crown:

●       Monolithic: The crown is made out of a uniform piece of ceramic without individual layers fused together.

●       Bi-layered: This type of crown is supported by a structure core (magnesium aluminate spinel and lithium disilicate) where the laboratory technician applies veneering porcelain to create the final esthetic restoration.
