Dental Crown (PFM) chip, does it need to replaced? (Photos)

Question

Hi I have a PFM crown on a back molar which is probably 12 years old and I am hesitant to replace it as I don't have a problem with it even with the chip. The dentist recommends I replace, the x-ray looked fine - it does not have a root canal done. I've posted some picture I took and wanted to get a idea if I can leave the existing PFM without any issue. I don't want to go through the experience of replacing it but if I do have to replace it what crown should be placed to avoid this problem. Thanks

Hi:In your case the tooth is still protected by the metal under the porcelain.  The main concern is the bite and food impaction in the area of the missing porcelain.  If either one of these problems exist it is better to replace the crown.Best,Dr. Maddahi

Without more diagnostic information it's impossible to answer your question. I suggest you follow your dentist's advice.You can substitute a gold crown if you want to be absolutely certain there will never be a fracture.

Jean-Paul Banh, DDS · Answer

If the fracture is purely esthetic (ie. porcelain) and does not affect the margins or the integrity of the crown, you do not need to replace it.  If you do need to replace it, I would suggest getting a metal occlusion instead of a porcelain occlusion.

Recent crown doesn't fit well against next tooth and food is getting stuck constantly.
