Blue dot on my gum? (been there for a long time)

[Peach]

I've had this blue dot (I wouldn't really call it a spot because it's pretty smallish) on my gum for years. I think it appeared around the time I had a tooth taken out, but I don't remember if my dentist at the time ever saw it, because I stopped going. I googled recently wondering what it was (I used to think it was a nerve), part of a silver filling perhaps but I only remember having white ones. It isn't raised at all and I don't think it's changed much in the years it's been there. I can try & get a pic if necessary, but yeah... does it sound harmless? I would prefer if a dentist could answer because I'm panicking a bit after the stuff I read.

Its probably an amalgam tattoo - a bit of silver filling - and nothing to worry about, but get it checked out all the same.

I will do. it definitely looks like that from the pictures i've seen - I just don't remember having a silver filling, though I was quite young then. thanks!
