Smart coverage feedback guides you in real time, glowing yellow when an area of your mouth needs cleaning and blue once an area is cleaned.
Protect your teeth and gums with instant pressure feedback
Smart pressure feedback guides you in real time, glowing purple when you’re using too much or too little pressure and green when your pressure is optimal to help protect your teeth and gums.
Never miss an area for a complete clean
After your brushing session, post-brushing feedback on the handle’s display shows any areas that need a retouch, helping you achieve a complete clean every time you brush.
Feel the confidence of your best clean
