I had a crown lengthening on a molar tooth nine weeks ago and had the permanent crown cemented six weeks after the procedure. Six weeks after the crown lengthening, the area still feels sore when I bite. When I had my appointment to get the permanent crown, I told the dentist this, and he thought I was still healing after the crown lengthening. He took an x-ray of the permanent crown and said that the crown fits very well and is cemented. I have had the permanent crown for three weeks, and it still hurts sometimes when I eat. That side of my mouth still feels sore sometimes. Is it normal to feel sore for over two months after the crown lengthening? Is it possible that my gum needs more time to heal? Should I have waited longer for the gum to heal before having the permanent crown cemented? Or could there be an issue with the height?
