Dental Crowns Procedure
When a tooth is damaged to the extent that it is not possible to do a filling, inlay or onlay, a dental crown is the alternative. Crowns are dental caps placed on top of damaged teeth and are used to protect and cover teeth. The crown restores the tooth’s shape, size, strength and appearance. The dental crown is cemented into place on your tooth and it covers the visible portion of the tooth.
Old dental crown techniques often used a metal base with a porcelain material on top for aesthetics. Today, we use strong ceramic materials instead of metal. The only exception is a golden crown, if requested.
Using strong, enamel-like ceramic materials we can most often (depending on the case) fabricate a crown in a day or two. Thanks to our advanced digital scanners, there is no discomfort while we make dental impressions. A two-minute scan gives us all the information we need, in full detail and the highest resolution. In many cases, a temporary crown is fitted while the ceramic dental crown is being created. The ceramic dental crown once crafted is then cemented to the tooth – aesthetic, durable and strong.
The quality and lifespan of the ceramic dental crown depends on technique and time spent on the treatment.
A crown can look and feel right, but still have quality concerns. At Snö, we always document our procedures in order to ensure our high-quality standard. When a crown is suggested, you get a two-year warranty, irrespective of what happens to the filling. This can be extended to five years if you follow our maintenance instructions.
A damaged front tooth that had old composite fillings. Teeth were bleached before making the new ceramic crown.
The old technique to make a crown (at Snö we do not do this) with an inner shell of metal/gold.
The metal blocks out the light (left) and often discolours the tooth towards the gum. To the right, we have replaced it with a modern, biological, ceramic crown.
Front tooth fractured. The tooth (root filled many years ago) could, in this case, be lengthened with a ceramic post in order to place the full ceramic crown on top of the post.

To the right, the tooth has been root filled and a ceramic post (white) has been cemented to the root and a crown (white with lines) placed on top of the post.
Ceramic dental crowns can also as this case be made on implants.
