My CEREC crown chipped very big on my tooth number 18 with it only being in for 24 hours. Is this normal for a CEREC to break?

Question

My crown was barely in for 24 hours and broke. I didn't realize I was getting a CEREC crown and actually thought my crown would be done the old way, through a lab. I feel now that I don't have any confidence in either my dentist nor CEREC crown, being that this chunk fell off so soon, while eating a soft egg sandwhich. The crown also did NOT fit well at first and felt very high so he kept drilling or filling it to fix it, could this have compromised the quality?

Hi!  This is not normal.  Every time dentists adjust ceramic crowns there is a potential for microfractures in the porcelain that can compromise the integrity of the material.  It sounds like the crown might not have been designed properly.  It might have been slightly high and therefore broke because of excess force as you were biting down.  I definitely recommend going back to that dentist for a re-do!

Hi:Although I have a Cerec Machine in my office, I send the crowns to the lab since the material is stronger and the fit is much better.   My suggestion is go back to the dentist and have him replace the cerec crown with a regular crown from the lab.Best,Dr. Maddahi
