Crown Repair Possible?

That is the issue with the crown. I think due to some error during cementation (if the crown is prepared properly in the lab). Normally that results in a gap in the cervical area and no proper proximal contacts.

Thanks for your request.Mostly crowns can be replaced if necessary, providing the remaining tooth structure is sound enough to support a new crown. There may be some additional required, such as if crown open and touch your gum and also when you eate it can be difficult to clean the food if you have spaces can entering the food. providing a ‘core build up’, or root treatment, but as long as the remaining tooth structure is adequate to support a new crown, it can be successfully replaced with a new restoration.
