With the sensitivity mode and pressure sensor, the toothbrush automatically stops pulsations when brushing too hard. It features 3 brushing programs and an integrated 4-zone timer to ensure the dentist-recommended brushing time of 2 minutes is followed. Personalized brushing is possible with the appropriate Oral-B brush heads, such as Deep Clean, Sensitive Clean, or 3DWhite. The long-lasting battery with LED charge indicator ensures optimal teeth cleaning at any time.
