I had a tooth extracted before Christmas, I was offered root canal but I couldn't have it done. I have had really chronic toothache since. The dentist said there is nothing showing up on the x ray and to try Sensodene tooth paste. I have been taking Nurofen plus, paracetmol ( not together ) 3 times a day, honestly I am not a wimp when it comes to pain but it's really dragging me down.
