Cerec crowns are great
Cerec crowns look and feel great. They're also reliable and should last a good while. The biggest advantage is that they can be created in just a day.
We have an in-house lab in our office with an expert in technician working on every Cerec crown, when made correctly they truly look amazing. Good Luck!

Disadvantages of CEREC crowns
After using CEREC technology for over ten years, I can tell you there aren't three real disadvantages to speak of. There are however more than three advantages. They would include single visit capability, complete control of the shape, contour and fit by the Dentist, and strong durable metal free restorations.

Disadvantages to CEREC
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.

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.

I had three Cerec crowns installed in 2009. It is now March 2013 and two of the three have broken. I don't chew gum or eat hard foods. While they might look nice, these crowns are brittle.

Dr Wu is very enthusiastic about his CEREC, understandibly so. It is great technology. There are however a couple of minor mis-statements in his post. First, the tooth colored material these crowns are milled from is in fact a metal even though they are tooth colored. The materials used are either dilithium silicate or zirconia, both of which are metals on the periodic table. Picky, I know but true. The fit between the crown and the tooth, while very good and totally acceptable, is far greater than the gap between a conventionally cast crown and the tooth. Both gaps are filled with cement but the CEREC gap is approximately 8 times greater.
