As one of Oral-B’s premium replacement toothbrush heads, the CrossAction features perfectly angled bristles at 16 degrees that target plaque to remove up to 100% more plaque vs. a regular manual toothbrush. Oral-B’s improved CrossAction toothbrush heads are developed with CleanMaximiser technology that turns green bristles yellow for optimal brush head performance and the best clean. The unique bristles reach deep between teeth to remove plaque and leave your whole mouth cleaner than with a regular manual toothbrush. Compatible with all Oral-B handles except Pulsonic & iO.  Packaging may vary.
