Two weeks ago I went to my dentist and received 2 Root Canals, 1 Tooth Extraction(rear Molar), and a Filling. this Dr. was extremely heavy-handed, she was actually leaning with her palm on my lower jaw while doing my root-canal until I SAID SOMETHING.now two weeks later I cannot open my mouth barely wide enough to bite a slice of bread without having severe pain in my jaw, my ear, and the side of my nose. And once I get past the quarter-inch it sounds like my jawbone is cracking in my ear. I feel like there is a problem, the pain is so bad I have to force myself to eat' and I'm losing weight because of it. Is it possible that my jaw is fractured.
