Big nostrils, big labret, big lobes, and a forehead Star of David, but remember — if you don’t brush your teeth often enough, they’ll be permanently stained yellow! So don’t skip the top row or you’ll end up with golden teeth too. Seriously though, I think if I ever do any tooth mods myself, I’m getting warthog teeth. That’s what I really want — big lower jaw tusks like a troll or something.
PS. I’m not kidding.
