Cavities, irritated pulp, uneven bite?

About 3 months ago I had around 8 cavities filled, most of the cavities was on the right side of my mouth and a few was on the left side, the deepest one was on the left side. Well when they filled them it seems like they shaved my actual teeth down on the right side of my mouth where most of my cavities were, and on the left side they didn’t shave any teeth at all. My mouth feels off, I don’t feel the feeling I feel my teeth on the left side when I close my mouth and not the right side, also they placed a filling right over the pulp and now I’m in pain 24/7 from a irritated nerve, I recently went to a new dentist (I moved) and the dentist made me bite on a piece of paper and she pulled it and I could tell the right side of my mouth really gripped on to the paper and the left side did as well but not nearly as much it still had some pull and she said it was a good thing I still had my natural teeth shape on the left side of my mouth but how can they shave down one side and not the other side??? It feels so off. I’m going back on the 17th to get the deep filling removed and they are gonna put a pulp cap and new filling to hopefully help with the irritated nerve touching the filling but how else can I explain to them my bite feels so weird now???
