i briefly wore braces for 9 months when i was in 9th grade. because my wisdom teeth came in and pushed my front teeth into overlapping.
this has left me with nothing but a snazzy retainer, as my teeth still drift back from time to time.
when that happens, i get to wear my retainer and feel like i'm 13 again! rejoice!!
You only have to wear one "from time to time?" Be thankful; my teeth don't fit together as they should, so I'll probably have to wear mine for the rest of my life (though mercifully only at night). Mine's not wire, though. It's one of those clear ones that's fitted to your teeth.
