this can happen for 2 to 3 months after filling replacement. it should be lessening over that time. if it doesn't, sometimes the fillings have to be done over. i would recommend getting a biocompatibility test if you have not already done so. if the fillings were very deep, it is possible you need some temporary medicated fillings for a few months before replacing them with regular ones, but generally that is when only one or two teeth are sensitive. check to see what filling material was used, because some is worse at causing sensitivity. i would try neydent toothpaste. it is better than sensodyne, click here
