I think one of mine at least is impacted. As for straight teeth...well mine aren't so much. I'm considering getting work done because it might help my breathing but I don't want jaw/palate breaking surgery, and braces...well, not sure on that one either.
I still have tow wisdom teeth that need pulled out. It's not a pleasant experience but it's also not all bad either. I got my top ones pulled and it's really helped my mouth overall since then.
