Dr. Fresh, Buena Park, Calif, introduces the Spiderman light up toothbrush with FireFly technology.  The toothbrush features a molded Spiderman character handle and soft Dupont bristles. The light-up FireFly feature flashes for 60-seconds at a time (the length of time recommended for thoroughly brushing one arch) as a child brushes. The light stops blinking after 60 seconds to indicate when it’s time to move on to the other row of teeth and start the light again. The light stops functioning after approximately 3-months of use to let parents know when it is time to purchase a new toothbrush.
