constant pain after crown

Hello--I had a crown completed on upper left molar 7 weeks ago.  I had no pain before the crown and had crown done due to advice from my dentist--he said there was a crack on the tooth.  I also had very little/no pain while wearing the temporary crown for three weeks.  I felt enormous, intense pain while the temporary crown was removed and the permanent crown put on.  I have been in pain ever since.  The pain hasn't gotten better or any worse--just a dull, aching pain that makes the entire side of my head hurt.  I returned to the dentist 3 weeks ago and had an  x-ray done--the dentist said it doesn't look like I have an infection.  He applied ice to the affected tooth---shooting pain!  He then said I possibly have reversible pulpitis.  I am not sure if I accurately communicated to him that my pain is constant.  Right now, I take 200 milligrams of ibuprofin every four hours, and my pain is manageable.  But I don't want to live like this any longer if a root canal is inevitable.  I am really hoping that the tooth will get better on its own.  Part of me thinks that the tooth was so aggravated by the permanent crown being put on, that it is just taking forever to heal--but of course I don't know that for sure!  I just want advice whether or not I should seek root canal treatment.  Thank you.

Occlusal interference is commonly created  from molar restoration, especially a crown.The best solution is probably occlusal adjustment of the new crown. However, occlusal adjustment of molar is not easy.

I understand adjust the heigth of the crown to relieve pain when pressure from eating is applied. The crown was adjusted and there is less pain.
I have headaches on the left temple. I am not a headache person. I have pain in all of my bottom teeth on the left side and in my neck on the left side...I am looking for suggestions.
Thanks for your time.
