OK so on Monday Nov. 7 2011. I had a Root Canal done on my lower right, !st premolar or biscupid i think its called, anyway. Ive had a Root Canal before and from what i remember, everything seemed to go fine. So procedure was finished and i went home. Shortly after, the numbing went away and i felt my lower right part of the jaw, in front of the tooth with the RC, was starting to get swollen. I feel like this is normal so i just let it be. Swelling was slowly going down, but by the third day i noticed swelling right under my chin. It first started under the right side of my chin and slowly made its way towards the middle. Well Friday the 11th and pretty much most of the swelling has gone down in my face but the swelling under my chin has gotten bigger. I look i have a double chin, or had that "fatbooth" app put on me in real life. the tooth itself i still sore and painful but bearable, but unable to sleep, but the swelling under my chin has its own pain as well. Is this normal???
