Painful sore jaw after fillings every evening- 1.5 months out

I had a ton of fillings 6 weeks ago. On my bottom left mid-molars, something with one of these fillings didn’t go right. Every evening I develop horrible jaw soreness. I’m avoiding chewing on that side. I’ve seen my dentists 5x to fix it and so far she’s put something on my teeth for tooth sensitivity, given my high fluoride toothpaste and placed more filling. She said the fillings were never on top of the molars, but I remember feeling them a bit too high early on. Not as noticeable now with my bite. Dentist says she doesn’t think I need a root canal.

I’m at a lost with my repetitive, evening jaw soreness. I’m not a teeth grinder and I actually feel better in the morning and with advil.

Is tooth sensitivity really causing this?
