Can you see if there is a leak or open margin of the crown through X-ray?

We cannot see clearly whether it is open or not on the x-ray. However, the appearance of metal parts may suggest that the porcelain is broken. The reason for this may be clenching of your teeth. For this, go to a periodontologist.

Actually, it is very difficult to see the open margin of the crown , but at least we can see a possibility if there is a part that has caries in that area and is not in harmony with the crown. You can share your x-ray with us, we will evaluate it.
