I went to the dentist to get the new crown put on this morning. I guess it should come as no surprise that this one cracked in exactly the same spot. My dentist said he has never seen this happen before. They called the lab guy to come over and look at it. He seemed equally mystified and declared that he would fix it and took off with the crown. My dentist isn’t holding out a lot of hope that the next one won’t crack too. I have the other cracked crown back on and still hoping it holds out till I get a non-cracked crown.
