Bristles are trimmed in a scalloped (or contoured) pattern to fit the natural shape of teeth. The peaks and valleys along the length of the brush head are ergonomically designed to follow teeth topography and fit in between teeth.
The larger surface area and contoured bristles of the brush head are designed to fit the natural shape of your teeth. The brush head works with your choice of brushing modes on the toothbrush handle for a thorough clean every time you brush.
The science behind Sonicare brush heads means less dependence on the brusher’s technique to get the best results because the handle and brush head function properly in concert with each other. By radial trimming the bristles to follow an arc instead of a straight line, a larger surface area is created without increasing the size of the brush head platform. The outer bristles also angle out at five degrees to create a wider surface area. The curved face across the width of the brush complements the contour fit down the length of the brush to help maintain contact with the surfaces of teeth and gums as the brush head pivots, maximising the sweeping motion performed by the brush head.
