The Oral-B Professional Deep Sweep 4000 Rechargeable Toothbrush offers comfortable brushing at a great value. Deep Sweep combines the familiar brushing motion of a manual toothbrush with triple-action, deep-cleaning technology. The Deep Sweep brush head has been designed to mimic the shape of a regular manual toothbrush, but has been engineered to clean exceedingly better. In fact, you can brush like usual and easily get up to 100% (two-times) more plaque removal than with a regular manual toothbrush. Power up the handle and the three specialized cleaning zones activate. The Power Tip reaches back teeth, shorter stationary bristles provide a thorough surface cleaning, and longer sweeping bristles penetrate deep between teeth, all for dynamic triple-cleaning action. Now you can brush as usual and achieve revolutionary results.
