If ever there was a reason for noise-canceling headphones, dental drills might be it. A prototype dental-noise-canceling device piggybacks onto your MP3 player and headphones, blocking out the high-pitched drill and dental noises while letting the dentist's voice through.

But the real payoff here isn't getting to avoid annoying, high-pitched noises The hope is that people who avoid going to the dentist in part because of those noisy implements of discomfort might feel more OK about going to the dentist, and thus partaking in the health benefits that come with healthy teeth and gums.

And if the noise device doesn't work? There's always Muhammad Ali, who knows how to fight tooth decay. [LiveScience]

As always, we hope you'll share an awesome link in the comments at least three times a day.
