I recently had 2 root canals done Today and last week which seem to be fine so far. But whats suprising is a regular filling for a tooth that had a cavity kinda aches when press against it with my finger? Ive never had this problem, should I just wait a few days before calling my dentist? I'm hoping its not a nerve problem, because I seriuosly dont want to get another root canal. He told me it didnt need one, just a filling. Anyone ever had minor aches on a tooth (it seems more sensitive to cold and hot now than before too) that had a new filling?
