I had a crown put on in January and it has been hurting ever since. The dentist sent me to an endodontic place and they said I don't need a root canal. He took off the permanent crown and put on a temporary. I still have the same symptoms. He sent me back to the endodontic place and they said my biological width is violated and I need crown lengthening. Should the dentist pay for that procedure because he didn't respect the biological width?
