Hey guys just had the first part of root canal therapy a week ago. Am going next week to finish the procedure(fill the tooth and prepare for a crown). I had a sizable infection around the root, so the dentist did the first part of the procedure, and prescribed me Penicillin V for the infection. The cavity that necessitated the root canal was quite deep and well into the nerve; far enough into the tooth that part of it had broken off(a small piece well above the gum line). AFAIK the dentist had to clean out quite a bit of the decayed tooth. The open root canal is currently filled with temporary filling putty. Number 19 molar by the way. So my questions seem to be as such: Is it normal to be having pain a week after a root canal? Nothing particularly sharp or severe, but biting down on the tooth lightly generally causes a certain amount of internal pressure and aching. Are the nerve endings around my root bruised, or do you think I might need a retreatment and second course of antibiotics? I am also afraid the tooth might have cracked from the work considering how deeply decayed it was, but I'm told the pain from that would be more severe. The aching isn't severe, maybe a constant 4 but calms down somewhat to a 1 or 2 at times. An 8 or 9 being the original pain from the decayed tooth and exposed nerve. The dentist prescribed me 15 Vicodin and I find taking half of one calms it down well enough to function normally(wish I had them earlier lol). The tooth itself doesn't seem overly sensitive to hot or cold which I'm told is good. What I am being told by others though is that there should be no pain at all after a solid week. It seems mostly centralized in the jaw and gum more than the tooth so it might be the infection being stubborn. Just curious to hear others' experiences.
