My dad's are like that and he went to a dentist a few years ago that told him "we need to get those out of there". My dad was just like "why? They haven't a problem til now and I'm almost 70." He did not go back to that guy.

"Impacted" sounds like unbearable pain. No? Got a good story about mine. Bear with me.

Got my top 2 out because they erupted sideways, actually cut my finger, thought it was a stuck Dorito. Shit had to go. Got the bottom 2 while I was under general.

First time completely under. Dentist said I wasn't going home until my gf could drive me. Great! Woke at home with her hovering over my face. She was a little bitchy when I asked how I got home.

"You don't remember that? Nothing?!"

I had refused to leave the comfy office bed, fought and cussed. Whole waiting room heard:

"FUCK YOU! I'll take you back there and do to you what they did to me!"

Jesus. (Nurses right about now: Yep. And I know OP is a guy.)

Same, they told me I would need oral surgery and to break my jaw open. No thanks. Occasionally they twinge and hurt, but I suppose I haven't died yet.

One of mine is like that. The dentist said to just ignore it unless it gives me trouble, or if I'm planning extended stay in the developing world, then I should get it removed before I go, just in case.
