I had them removed in March. Mine were pretty much fully in which is early for 18, but they were completely straight. I wanted them removed just so I'd have more space in my mouth and my mom didn't want me to have to go through any more of the growing pain. The extraction itself was fine, although my fourth one fell into my throat and I had to lean forward to get it out and there was blood everywhere

I didn't have much pain afterwards and I didn't even touch my pain killers. The worst part was probably the bad breath and bad taste in your mouth for the couple weeks afterwards. I was putting mints in every hour at school because I felt disgusting.
