I'm thinking it went okay. I went in to get a loose tooth fixed. I didn't get an actual oral cancer exam, but he looked at the grey spot - He said it could've been from the filling (Eventhough it's not a silver filling).
He did a full Xray session, and he didn't mention anything about any cancer (he took xrays of my whole mouth, and looked at the gums, kind of).. So, I'm assuming that is a good sign.
I don't know where I would've gotten that grey spot from, but he said it had been there for awhile, and it's nothing to worry about. Doesn't sit right with me, but I'm not a dentist.
