It’s Tooth Tunes, Hasbro’s toothbrush that plays two minutes of a song whenever your child brushes his or her pearly whites.

The science behind Tooth Tunes is a chip placed in the toothbrush’s handle that transfers vibrations through the bristles to the teeth and jawbone into the inner ear, making it audible only to the user. And, presumably, people standing in close proximity.

Some of the artists and bands appearing on Tooth Tunes are Vanessa Hudgens, KISS, (As Hannah Montana), Queen and, appropriately, Smash Mouth.

But the real beauty, at least for the labels, is that each Tooth Tunes only plays one song. If your kid wants a variety of tunes for brushing, then it’s back to the store for more Tooth Tunes. At $9.99 a pop.
