Severe pain after root canal and filling?!?! ?

Yesterday, I had a route canal and a filling done. On the bottom left side of my mouth, both right next to each other. I had to get about 5 needles of Anesthesia. On top of that they put a metal thing around both of the teeth and I don’t really know what it was for. Anyways, after the numbing wore off it was a little sore but nothing terrible. Today, I am experiencing severe throbbing pain. It hurts so bad, ibuprofen doesn’t even do anything for it. I realized it’s not the tooth I had a root canal on, it’s the filling. I have a temporary filling in, which not the dentist, but the dentists assistant put in, without checking if my bite was even or anything, she just stuck it in there and called it a day. I thought that was a little weird. Whenever I bite down I can feel my Teeth hit the filling tooth first and it is very tender and hurts. My gums are not inflamed or anything but my tooth and jaw hurt. Please help.
