Crowns & Bridges

Crowns are done to restore teeth which are extensively damaged and cannot be restored by simply filling them. Root canal treated teeth are often weak and may require crowning to restore normal function.

To prepare a crown, the tooth must first be reduced to about half its original size. An impression is then taken of the stump and a temporary crown is usually placed over the trimmed tooth.

The case is then sent to the laboratory where the technicians will fabricate the crown. Once the crown is ready, it is delivered back to the clinic. The dentist checks the crown for fit after removing the temporary crown and permanently cements the crown.

There are a few types of materials which can be used to fabricate crowns. The material of choice nowadays is zirconia. Crowns made from zirconia are more durable and aesthetic than porcelain fused to metal crowns (PFM).

Zirconia crowns are metal free. Even with wear and tear, no metal will show. Their translucency also make them more natural-looking. The porcelain in PFM crowns/bridges tend to look opaque. They lack the translucency of natural teeth.
