Too Much Pain with Crown!

I had a permanent crown placed about four weeks ago. I didn’t have any issues with the temporary crown, but ever since the permanent one was put on, I’ve had this constant, sharp ache. It’s more annoying than painful, though sometimes it gets bad enough that I need to take Advil.

It doesn’t hurt when I eat, and I’m not sensitive to hot or cold. My dentist took X-rays, did an exam, and ran some sensitivity tests. Everything looked normal, but he said the only other option would be a root canal. I’m wondering if I should give it more time, but I don’t think it should still be hurting after four weeks.

Any thoughts?
