My temporary crown is causing extreme pain with any pressure (no root canal on tooth).

Had cracked tooth with no pain re-filled, caused pain with certain foods and cold sensitivity. New dentist recommended crown due to size of filling but re-drilled/re-filled, no more cold issues but still pain with certain foods. Had prep work and temp crown 5 days ago and still have a LOT of pain with ANY pressure on tooth. It's not high. Been about 2.5 months since initial filling. Will this go away with the perm crown? Do I need a root canal?
