The Philips Sonicare Premium Plaque Defence replacement brush heads are designed for adults who want a deeper clean. These white, oval-shaped heads feature a soft-touch design with a dense cluster of medium-soft bristles in a pentagonal shape at the center, which helps with whitening and polishing the teeth. By supporting dynamic fluid action, these heads allow you to clean effectively between teeth and along the gumline. When used in White+ mode, they can remove up to 10 times more plaque than a manual toothbrush and up to 100% more stains in just three days. They are compatible with most Philips Sonicare handles, though they do not work with the Philips One line.
