Zirconia Crown on 30 &31, 3 weeks later I have jaw pain and 31 doesn't even make contact with #2. Any suggestions?

Never had any pain in my jaw before prior to this. Wondering if the pain in my jaw is due to 31 and 2 not making contact? I saw the the dentist yesterday and he filed down a crown on my other side when I told him of my problem and said it could take a few days for me to feel relief...Is he correct or shouldn't my back tooth #30 be making contact with my top back #2 tooth. I can literally bite down on a piece of paper back there and slip it out unscathed....Thanks for your advice in advance!!
