Hello! I'm seeing my dentist on Monday so I'll ask him this but in the meantime, I thought I'd ask here! After a long time without going to the dentist due to a mental issue (agoraphobia), I got a filling done on a cavity that I've had for a while. The cavity was deep, but not so deep that I needed a root canal. My dentist told me it'd be sensitive for a week or so, but to talk to him if it gets worse or if there's any throbbing pain. I understand that because the filling was deep it'd be more sensitive, especially because I waited so long, but along with the filling hurting, I have arm weakness in my right arm, my jaw hurts, and the pain feels like my tooth's being stabbed. Since I mentioned that I have anxiety issues, I'm well aware I could be grinding my teeth, especially at night, but I wanted to ask this anyways: Can tooth pain cause arm weakness? Can fillings cause arm weakness? What could be wrong with my tooth?
