This whole process began in late November. I began feeling pain in a lower molar when I would bite down. After seeing my dentist, he informed me that I needed a root canal and a crown. Throughout the entire process, the tooth has never felt normal. My dentist kept telling me, "It's (old filling, temp crown, and now new crown) a little high," and then he would trim it down. The permanent crown was put on three weeks ago. I went to the dentist one week ago becuase the tooth is still sore- sore to the touch and it hurts to chew on something hard. I would describe it as feeling the way it feels when you touch a bruise. It also seems heat sensitive. I returned to the dentist Saturday to see an "associate" of my dentist. He took and x-ray and told me the root canal looked good and the seal on the crown was good. He told me I needed to talk to my dentist. It was as if he didn't want to get involved. He wasn't helpful at all. So, I have another appt. with my dentist on Tuesday. Does anyone have any idea what could be going on with my tooth? It's very frustrating. Thanks for any help!
