The bristles on Close-Up's Right Angle toothbrush are arranged in a dynamic pattern that features a slight bow in their height. This layout helps them scrub away plaque as they shuffle over your enamel and along your gum line. Once the bristles have done their job, the back of the brush cleans the tongue, sweeping away bacteria pocketed around the taste buds. At the other end of the toothbrush, a textured grip comforts hands fatigued from a long day of typing, breaking rocks, or reinforcing opinions with dramatic gestures.
