However, a 'fractured jaw' normally refers to a break in the lower jaw (mandible). That's a remarkably solid piece of bone, which requires a really violent impact to break it. The dentistry that you've endured is far more likely to have caused bruising to the soft tissues around your jaw, with possible muscular tears, than to have actually broken your jaw. (Even a hefty punch to the jaw doesn't always break it, as any boxer will tell you. You need to be hit forcefully with an iron bar to get be sure of getting your jaw broken!)
This isn't written from an entirely theoretical viewpoint. I've had a tooth extracted which came out in over a dozen parts. (The operation was commenced by a final year student, who had already qualified and was about to set up in private dentistry. After an hour and a half he handed over to the Professor of Dentistry, who took another hour to complete the work). My jaw was swollen and painful for nearly a fortnight afterwards.
