Power toothbrushes are electrically powered with pulsating or rotational action. Sonicare advertises a power toothbrush that is rechargeable, cleans with high speed bristles and is said to remove stains. Like many power brushes, this particular model also provides a two minute timer and a 30 second interval time. Another manufacturer of power brushes, Braun, features a power brush with apparent floss action and bristles that penetrate spaces. The pulsating, rotational action of power brushes is convenient for people with limited motor skills.
