My teeth and gums are dominating my thoughts. I have a black triangle that has appeared in the last couple of weeks and my gums are receding. The worst thing is that they are constantly hurting me. They feel rough and dry. I spend hours obsessing about whether my gums are receding more and whether more gaps will open up. I’ve had 2 weeks of steroid gel which didn’t help at all, and now I’m using a fake saliva gel to keep my mouth lubricated, which isn't helping. Please help, I’m driving myself crazy!
