Some teeth are best restored with CEREC crowns, to be sure, but there are details of your teeth that the dentist must consider before choosing the right type of restoration. CEREC is not the only choice that will work. If your dentist only thinks of that option, then she/he may be trying to use the cool new technology instead of thinking about what is best for you. I think CEREC can make beautiful restorations that equal the best traditionally lab made crowns, but sometimes, it is necessary to use the lab artist. Front teeth are a great example of when the artists' touch can make all the difference.
Their are absolutely NO DISADVANTAGES of getting a Cerec crown. CEREC crowns are done in a single visit by a state of the art CAD/CAM computer and milling unit. The accuracy of fit and the precision of the digital images are far better than any impressions or models made by an outside lab. Furthermore, the materials used are the most similar to your own enamel as far as wear, esthetics, and flexibility. Their is no metal in a CEREC crown, so the material is also the most bio compatible. Expect to get 20 years or more of life out of a CEREC crown.
