While the music and colorful LEDs provide fun and entertainment, the white LEDs help to closely examine and care for the back teeth and chewing surfaces. The DuPont nylon brushes made from non-toxic ABS deliver highly efficient cleaning with 22,000 brush head movements per minute. To prevent children from accessing the batteries, the safety mechanism offers adequate protection. The batteries can thus be easily installed and removed only with a screwdriver. Thanks to the advanced technology and entertainment value, the Bubble Brush makes tooth brushing a pleasure. With the 2-minute auto-timer, the Bubble Brush supports adherence to the dentist-recommended cleaning duration for teeth. Additionally, the 30-second interval reminds users to clean every area of the mouth. The cute wave-shaped holder for the electric dolphin toothbrush completes the design.
