I was going recommend also wearing a mouthguard, because I've always felt like they reduced the head trauma I experience if I fell, but a quick literature search indicates that their efficacy for that purpose may not be well-validated. :/

I'll need to try that next time. I've had some really hard spills, and the sound/feeling of teeth clacking together as my head (always in a helmet) hit the ground was definitely the most disconcerting aspect of the fall.

If you are in the park or pipe, that is a good idea
