Pain and sensitivity months after crown. Should I see a prosthodontist or an endodontist?

I got a crown several months ago. My tooth had no pain or sensitivity at all before but it’s painful and sensitive after the procedure. My dentist said it was high and adjusted it. He adjusted it 4-5 times. The pain was a bit better but still sensitive. I went to see another dentist but he said everything looks fine and adjusted the bite a bit more. Still not better. Still feel that it’s high. My dentist said I should see an endodontist. Not sure if that is right as xrays show my roots are fine.
