Oral-B iO Ultimate Clean White Refil Head has a unique 'Tuft-in-Tuft' structure, to reach deeper in between teeth and removes up to 100% more plaque along the gum line for cleaner teeth and healthier gums.
Features Tuft-in-Tuft bristles-with shorter tufts optimally positioned for surface cleaning and separate, longer tufts for interdental cleaning in hard-to-reach areas.
Bristles are precisely angled at 16 degrees to most effectively but gently sweep away plaque along the gum line.
Tufts are engineered in an innovative CrissCross pattern-for ultimate cleaning.
On Oral-B's signature round brush head, bristles are meticulously arranged to best surround each tooth for the best possible clean.
The only refill brush heads designed exclusively for-and guaranteed to fit-your Oral-B iO.
