About 6 or 7 years ago, I got a small spot on my gum, about a cm above my vampire tooth right side and I remember it stayed there for ages (months) and then went, anyway it has come back a few times this year in exactly the same place, nothing oozes out of it and it doesn't bleed, it can just get a bit sore and sometimes looks like a little white head! Some days it feels flat and other days it feels like a spot.

Please reassure me over this, I am petrified of the dentist and would be terrified of it being an abscess or something, but then surely it wouldn't have gone away for years, right?

I have been to the dentist 4 or 5 times since I first had it, but of course never mentioned it cos it wasn't there at the time!
