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 ensure highly efficient cleaning with 22,000 brush head movements per minute. To prevent children from accessing the batteries, the safety device 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 brushing teeth a pleasure. With the 2-minute auto-timer, the Bubble Brush supports adherence to the cleaning duration recommended by dentists. Additionally, the 30-second interval reminds users to clean each area of the mouth. The cute wave-shaped holder for the electric dolphin toothbrush completes the design.
