The gently round-tipped CUREN® filaments absorb considerably less water than customary nylon toothbrushes, resulting in their lasting dimensional stability. Custom designed micro cleaning particles on the brush‘s exterior bristles remove plaque and persistent stains gently and effectively without any wear to the particles themselves. The densely arranged CUREN® filaments in the middle of the brush head gently polish and clean the tooth surface. A small, compact brush head and an octagonal handle allow for the brush to be held at a perfect angle for gentle and effective cleaning of even the most hard-to-reach areas in the mouth. The whitening toothbrushes – available in white and transparent – perfectly complement the whitening toothpaste.
