“CEREC” Crown Came Off Again

My “CEREC” crown came off for the 3^rd time. It’s not really CEREC but the dentist I got it from couldn’t or wouldn’t tell me the real name of the crown. It’s a generic form of CEREC but looks just as good or better than CEREC. That’s all good but the problem is it won’t stay on. This is the 3^rd time it came off. I have an appt on Tuesday to get it cemented back. I am just wondering why it would keep coming off. Thanks. M. Lombardo

M. Lombardo – We’re sorry to hear that you are having difficulty with your crown. There are several factors that can contribute to lack of stability in a dental crown.

• Shape and size of your natural tooth – A dental crown is placed over and cemented to your natural tooth. If your natural tooth is shaved down too much, or if it’s too angled, stability will be an issue.
• Accuracy in the crown construction and placement – A crown that is accurately made should completely cover your natural tooth to the margin of your gumline. Any gaps can cause the crown to loosen and come off.
• Improper bonding technique – Careful bonding technique helps to ensure that the crown is secure. Incorrect technique or insufficient tooth structure to which a crown is bonded can cause the crown to loosen and detach.

Speak with your dentist and ask him or her why your crown is repeatedly coming off. If you don’t receive a satisfying answer, or if it continues to come off, consider getting a second opinion from a dentist who offers genuine CEREC products and is experienced in crown placement.
