Yes OP, I am in the exact same boat as you. I was notified my gums were receding on my uppers on the inside.
I'm obviously nervous like you and have stopped using my harsh Sonicare toothbrush (I shouldn't label the device as "harsh", but it's very effective and I used it very aggresively) and gone back to a manual brush. I have also not used the swirling motion for brushing so much and have used more of a brushing downward motion all in an effort to prevent further recession. I was told, though, that the grafting surgery is most likely the only way to fix this problem. <sigh>
Please let me know if you go through with the surgery and how it went as I am very hesitant as well. I, of course, will do the same if I get the guts and time to do so.
