What causes severe tooth sensitivity and ear pain after dental filling?
Patient: I had a filling one week ago.  I started having pain in that tooth before the feeling came back.  I contacted my dentist and was seen.  He then performed an x ray, it revealed nothing.  He prescribed Norco 5mg.  It helped for a very short time.  Now I am experiencing severe tooth sensitivity as well as severe jaw and ear pain. Doctor: Hi,As per your complain slight sensitivity of tooth after a dental filling is not abnormal finding and can resolve in 2 to 3 days. But in your case it seems that it is not just sensitivity but considerable pain that is also radiating to Ear and jaw and it is a clear I education of nerve exposure that needs Root Canal. Treatment of tooth and not just filling will work. At times in acute condition the x ray is not diagnostic and clinical symptoms has to be taken into consideration for diagnosis.If I would be your treating dentist I would first of all remove the filling under local anesthesia and start Root Canal treatment to reduce pain and discomfort. It will be followed by a course of antibiotics and painkillers. After completion of root canal treatment, tooth will be capped to provide strength to it. So better consult an Endodontist and get evaluated so that he can treat you accordingly.Hope this information helps. Let me know if I can assist you further.Thanks and regards,Dr. Honey Nandwani Arora
