Colgate 360 degree Advanced Optic White whitening toothbrushes feature an advanced multi-action bristle design (vs. an ordinary flat trim toothbrush) and an innovative cheek & tongue cleaner design to remove bacteria from teeth, tongue, cheeks, and gums. The toothbrush also features spiral polishing bristles that help to remove surface stains from teeth, for a naturally whiter smile. It also features an ergonomic handle so that it fits comfortably in your hand. Flexible finger grips help the toothbrush to stay in place; reducing slippage and allowing for more precise maneuvering as you brush your teeth.
