An impression is taken and a temporary crown is placed over the top of the prepared tooth. The impression is sent to the laboratory and the crown is then fabricated. The next appointment usually between 2-3 weeks later involves cementing the permanent crown in place. If all goes well, this appointment takes 30 minutes.
Crowns. A crown is a tooth-shaped cap that's placed over a weak or damaged tooth to improve its shape, size, strength, or appearance. Most crowns last five to 15 years and can be made of metal, porcelain fused to metal, resin, or ceramic. Before a crown is seated, the existing tooth is filed down; then the crown is cemented over it, fully encasing the tooth. Onlays and three-quarter crowns cover the underlying tooth to a lesser extent.
