U-Shaped Sonic Brush 4 Modes 1908 Bristles

This ultrasonic U-shaped electric toothbrush incorporates 1908 precisely arranged bristles — a documented upgrade from the 768-bristle third-generation model — to strengthen cleaning thoroughness and gum massage effectiveness. The brush head has been externally tested for anatomical fit and functional performance. It offers four clearly defined one-touch modes: Powerful (for robust plaque removal), Moderate (for gentle daily maintenance), Gum Massage (to support periodontal health), and Whitening (combining sonic action with blue light for progressive surface brightening). Users clean all teeth simultaneously by gently biting the U-shaped head and swaying left to right — eliminating the need for manual brushing motions. Designed for shared use between adults and children, it supports efficient oral hygiene within constrained time windows.
