Uneven bite due to new crown? Please help. Thanks.

I just got a crown placed that made my bite too high on that side. I returned and expected the crown to be filed to fix the bite, but instead, the dentist filed some of the tooth above it first, then filed the crown down a bit. I thought it fixed it, but now I feel a higher bite on the other side. Why would she touch the tooth above that wasn't the problem then address the crown that was the issue? Do I have to find someone else now to fix what this dentist did? My bite was fine before this.
