In August of this year, a dentist I went to told me to use Sensodyne for the pain around the root canal teeth and two molars that are amalagrams and were swollen. He also did some kind of a sealant that really hurt. I have had pain since March and his treatments don't help. Second opinion, please. I did and as soon as I can, physically, I am getting the bad teeth, all 8 out. If these dentist's had pain, they wouldn't just treat with Sensoydyne!
