Hi, I am 22 years old with gum recession on teeth 8, 9, and 7, especially 7. I have been told by a Periodontist that I should get a gum graft on 7, that there was bone loss. He did not acknowledge the recession on 8 or 9. I asked him twice if the recession was from gum disease, and twice he said no, saying it was "anatomical." He also said it was not from improper brushing. I had another dentist tell me the same thing two months before, when the recession was less noticeable. What exactly does that mean, and how do I keep it from getting worse if I can't ascertain the cause?
