I have this same exact thing. I don't know what you mean by hard or soft, it's almost like it's part of the tooth. No sticking or sensitivity in my case.

Yep, same here. Doesn't seem to be sticky when I floss, doesn't hurt at all, just an ugly black spot.
Disclaimer: I drink mass doses of caffeine daily- but I would think that would lead to overall staining, not one spot.
