[Three powerful cleaning modes - Gentle Intense or Everyday Built-in timer for convenience - A short pause at 30-second intervals acts as a reminder to brush all 4 quadrants of the mouth equally. The toothbrush will power down after the recommended 2-minute brushing time. Soft-tapered bristles for effective cleaning - We recommend replacing the toothbrush head every 3 months or when the head becomes worn with a relevant Hismile Toothbrush fitted head. Mode memory to suit your brushing needs - To cycle through modes press the power button until desired mode is selected. Brush for 2 minutes.]
