Tooth Sensitivity After Permanent Crown Placement, Also Affecting Non-Crowned Teeth?

It is possible that the filling under the crown may have disturbed the nerve and the nerve is reacting to it. This usually settles down after a few days. If not, it can mean that a root canal may be needed. If the pain increases when you are biting down on it then the crown may need a bite adjustment which should not take long to fix at your dentist.

Hi:It’s best to go back to your dentist to check the bite on the crown tooth as a first meausure.  Normally bite issues only increase sensitivity over time.Best,Dr. Maddahi

First consider asking the doctor to check and verify that you bite is not high in both tap-tap-tap position and when you move your teeth to extreme side to side and forward positons. Sometimes there are interferences in bite, which can start causing sensetivity. It happened to me, as a patient! It lasted for 2 weeks untill I had a bite adjusted. Try that. If this does not work, consider changing a crown and a possibly a root canal therapy.

Cold sensitivity is normal with a newly placed restoration. 

 

It does sound like your bite may be off.

 

Go see your dentist and have them check the bite 

It sounds like your "bite" is not correct. The dentist must make sure that your upper (crown) and lower teeth meet each other properly when you close your teeth together as well as in all movements of your jaw.
 

When you place a new crown and the tooth is sensitive, usually it will go away after couple weeks. When there is a big cavity and it is close to nerve can be a reason to have sensitivity and roor canal recommended, also %5-10% of cases after preparation for the crown turn to having sensitivity due to different reasons and root canal should be done. Have consultation with your dentist. 

Cold sensitivity should subside gradually within weeks.  The fact that its getting worse should be further investigated.  An xray would show whether or not the crown is well fitting.  Sometimes, the cement used can be too acidic.  Also, the bite may need to be adjusted.  If all else fails, the crown should be removed, a new temporary crown made and worn for a while to see what happens with the sensitivity.  Should the sensitivity persist, a root canal may be in order.  The sensitivity on the other teeth could be due to "reffered pain".
