ratbastid: if your frenulum actually scrapes your teeth, you might want to have it loosened a bit, frenulectomy or whatever. Could save you from future discomfort, and I don't think there are any side-effects too it.
cheryl: nah, just overzealous maybe
Not like it's gonna be lasting damage as far as I can tell from your story. Just be a bit more cautious next time.
