Crown tooth sensitive to heat, why?


I had a root canal done and the crown placed on a pre-molar. 4 weeks later eating and drinking hot stuff this crown is hurting. How can that be if the nerve has been removed? I told my Dentist and he is convinced that I am making this up because God forbid that he might be wrong or doesn't want to take responsibility. It isn't the adjacent tooth because when I thumb on the crown it hurts. When I eat nuts or any hard food it hurts when chewing on it. What can cause this?
