Dr. Wiltbank of Dolley Madison Dentistry thought of the idea after the success of the ALS Ice Bucket Challenge that went viral on social media a year ago. You might be familiar with the Extreme Ironing trend or the extreme planking fad that became trending topics on Twitter a while back, but there has yet to be an extreme brushing challenge.

Challenge applications are encouraged to submit a photo of themselves (or a friend!) brushing their teeth in the craziest location they can think of. So far there have been submissions of people brushing at some of DC's most notable monuments, on the treadmill, and even on a hiking trail!
