The Oral-B Pro Cross Action toothbrush is a replacement head with more than 2200 bristles at perfect inclination, up to 100%more bacterial plaque, for cleaner teeth and healthier gums, than Oral-B manual toothbrushes. The new X -shaped bristles also successfully cleanse the teeth where round bristles do not reach.
For efficient cleaning, toothbrushing replacement is indicated by the color change of bristles, and bristles change from green to yellow.

It is guaranteed to be used with all Oral-B electric toothbrushes, except for Pulsonic and IO toothbrushes.
