Implant crowns feel wrong. How can this be treated?

I had implants done a few years ago, but had to redo crowns with three labs, as the could not make them fit my tight bite and look aesthetic. I had them installed permanently a few months ago. While they look ok, they feel wrong. I just want to rip them out. They seem too bulky in the bag, as opposed to my much thinner temps, and I have recently started having what looks like inflammation in that area. When they were installed, the dentist said they looked good. Please advise.
