Philips Sonicare Diamond Clean Toothbrush, Gently Cleans Teeth with Sonic Technology. Unlike a manual toothbrush, Philips Sonicare DiamondClean uses powerful Sonic technology to clean teeth with up to 31,000 brush strokes per minute. Sweeping motions drive fluid deep into the tight spaces between your teeth and along your gum line, resulting in a cleaner, healthier mouth.
