I had a root canal on my bottom left tooth(#19) 2 days ago, i've had 2 others with no pain, but this time it hurts. not the tooth itself but underneath in the gum by the jawbone, i noticed when i press on my cheek. my tooth feels excellent i can eat on it with no pain. i have a narrow jaw and as the endodontist said, long roots. maybe this has to do with the pain? its right by the nerve in my jaw, i can feel that much. im NOT experiencing any tingling or loss of sensation, it kind of feels like a bruise when you press, but on the inside,kind of prickly only when pressed. Im ignorant on how a root canal is truly performed, but i seen smoke and im wonderin did maybe one of the files go through a root tip and thats what im feeling? i'm so scared i have an abscess that i dont know about, but i dont see any facial swelling. hoping for the best..what could possibly/most likely be wrong? and what can be done about it?
