The Philips G3 Premium Gum Care Standard Sonic Toothbrush Heads come with Soft sides flex and adapt to the contours of your gums, giving you 2 x more surface contact for superior plaque removal at the gumline. With the Philips Sonicare Premium Gum Care brush head, even the deepest clean is gentle. As your toothbrush moves along the gum line, Premium Gum Care's flexible sides and bristles absorb any excess pressure so your gums are protected, even if you brush too hard. Bristles work hard to remove plaque and bacteria along the gum line, helping to improve gum health. Thanks to this brush head's curved design, you can be sure of maximised bristle contact. Soft rubber sides flex to let Premium Gum Care adapt to the shape of your teeth and gums, absorbing any excess brushing pressure and enhancing our sonic cleaning power. Bristles can then adjust to the shape of your teeth and gums so you get up to 2x more surface contact than a regular brush head for deeper cleaning even in hard-to-reac
