The ultra-soft and rounded bristles are suitable for sensitive teeth and gums, cleaning the teeth gently and thoroughly. The contour-adapted profile of the Dupont brush heads conforms to the natural shape of the teeth, allowing for cleaning in hard-to-reach areas. Its special wavy profile increases the contact area during brushing, thereby improving the cleaning results. In addition to efficient and thorough cleaning, the Shine Bright replacement brush head promotes a naturally whiter smile. Surface stains are effectively removed from the very first use, leaving the teeth shining in a natural, beautiful white!.
