Dental Crown pain

thanks for listening to my situation.
about a month ago my dentist indicated that my very back molar (upper right) may be cracked.
ended up with a temporary filling, then a temporary crown.
That went well until the temp crown fell off then I got a second temporary crown.

The second temporary crown must have been set a bit crooked because it kept biting the back of my tongue - hard!  Not during eating - but speaking - I had to be really careful when I spoke or I would literally bite my tongue - it was weird.

So when the permanent crown was ready the dentist had trouble fitting it - he had to drill the crown, drill the tooth (no root canal), back and forth until he finally got the crown to fit (it took a while).

Now I have pain in the permanent crown and it's really cold sensitive - is this because the permanent crown didn't seem to fit right initially? (had no problems with the temporary crowns - other than the tongue biting issue).  It's been two weeks since I got the permanent crown and the pain has not gone away (I wanted to give it some time since the dentist had such difficulty fitting it).

I'm going back to the dentist to have him look at it but what should I ask him? what should I expect?
thanks for your advice.
