It has obviously receded at some parts. My secret hope is that this was caused years ago during a time where my dental hygiene was not very good but it has stopped completely because I now take excellent care of my teeth. It used to bleed sometimes when flossing, it doesn't now. My worst fear is that it is caused by night teeth grinding (I don't know if I do this), because it will be completely out of my control. My dentist never really mentions my gums, I will ask next time. Is it possible to tell if it's still receding at this point?
