I had a Crown on a lower backmola, which came off.. i couldn't get to see the dentist for a few days, but I took The Crown with me to get him to put it back on. And he put it back on and now it feels much too big. It feels like he's put a Crown back on. That's 2 sizes too big, which it isn't. Because it was the same Crown that came off before. He said that it's because I've had a missing Crown. And I need to get used to having a Crown in that area again, but even so, it really does feel too big and he said, if it feels too big after a few days come back, but surely he should have adjusted it there and then has anybody else had that problem?
