You might not expect to hear “We Will Rock You” by Queen blaring from your kids’ bathroom before bed, but you will when they brush their teeth with the Tooth Tunes from Arm & Hammer. The technology behind the musical toothbrushes is really amazing–sound vibrations stream from the bristles of the toothbrush through the teeth, allowing kids to hear the music while they brush. Each brush features two minutes of music from one song to encourage longer brushing. Some of the songs available include “Dynamite” by Taio Cruz, “I Gotta Feeling” by the Black Eyed Peas, and “Just The Way You Are” by Bruno Mars, among many other of today’s top hits. Brushing has never been so cool ($9.99, retailers nationwide).
