When a tooth is fractured, has a large old filling, or is severely damaged by decay, we may recommend the placement of a tooth crown. Crowns strengthen and protect the remaining tooth structure and can improve the appearance of your smile. Types of crowns include full porcelain crown, porcelain fused to metal crown, and all-metal crowns. Because of the esthetic reasons, we do not recommend the use of all-metal crowns.
Please note that in cases when there is not enough tooth structure to retain a crown due to either decay or fracture, additional procedures may be considered prior to crown placement. These may include root canal therapy, post and core procedure, and/or crown lengthening.
Fitting a crown requires at least two visits to the dentist’s office and follows the following steps:
- Visit 1: Removing decay, preparing and shaping the tooth to fit the future crown. Making an impression of the shaped tooth. Making and fitting a temporary or transitional crown made out of plastic or metal. In cases when existing tooth structure is not sufficient to hold a crown, a core build up and post may be required.
- Visit 2: Removing the temporary crown, fitting and adjusting the final crown, and cementing the crown into place.

|Although these crowns are strong, they do not look natural because the base metal is dark and absorbs the light. This makes the crown look gray instead of white. Also the dark metal can be visible at the gum line making your smile less appealing and healthy. Finally, in extremely rare cases, some patients may suffer allergic reactions such as gingival discoloration, swelling and redness.||Excellent choice for durable, long-lasting crown that feels and looks just like a real tooth. Since gold is a light-colored metal, it reflects the light allowing the crown to shine and sparkle like a real tooth. Moreover, gold restorations can be cast more accurately and finished to a finer margin at the gum line. In addition, they are corrosion-resistant and can withstand the hostile environment of the oral cavity for extended periods of time.||These metal-free restorations provide optimum restorative solution for chipped, cracked or decaying front teeth. Because these crowns do not have a rigid support of a metal base, they cannot take the same amount of constant pressure and grinding as the crowns with metal or gold base can. Therefore, these crowns are ideal for the front teeth only as the majority of chewing is done by the back teeth.||This is a SUPER crown! Made out of a single zirconia crystal block, it as strong as a diamond. Virtually chip-proof, solid zirconia crowns are the ideal restoration for bruxers and grinders, implant restorations and areas with limited occlusal space. Designed and milled using CAD/CAM technology, they are sintered for 6.5 hours at 1,530 degrees Celsius. The final Solid Zirconia crown or bridge is glazed to a smooth surface.|
