Hasbro plans on launching a musical toothbrush called "Tooth Tunes" reports the WSJ.

"When pressed to the teeth, the toothbrush renders a recorded riff from a pop star that lasts two minutes -- precisely the amount of time dentists say children should spend brushing their teeth.

How does it work? "The two-minute recording is stored on a microchip no bigger than a dot atop the letter i. Push a button on the toothbrush, and a minicomputer starts playing the song. Sound waves are transported through the transducer to the front teeth, traveling from there to the jawbone and then to the inner ear.

Hasbro is in talks with several recording artists about getting rights to their recordings. Many artists would probably consider a gig in a toothbrush beneath their talents. But others might welcome the daily exposure in their young fans' lives."
