Product features:1. 360-degree bidirectional smooth-rotation brush head: Currently, most electric toothbrushes on the market use vibration technology. However, long-term use of vibration-based electric toothbrushes can lead to teeth becoming increasingly loose and gaps between the teeth growing larger, resulting in irreversible damage to the teeth. Therefore, our electric toothbrush features a newly designed bidirectional smooth-rotation brush head that scientifically mimics the internationally recognized Brushing Method (also known as the "Bass Method"). This design eliminates vibration, providing better protection for the teeth and promoting a healthier oral environment!2.
