2 count Spinbrush Smart Clean toothbrush replacement heads; handle sold separately. Removes more plaque in hard-to-reach areas than a manual brush; reduces surface stains by 50% after one week when used with regular toothpaste! Soft, triple-sided bristles are 30% longer to reach deeper between teeth; split-head design moderates the amount of pressure applied, so it’s gentle on teeth and gums when used with a compatible handle!
