For optimal oral hygiene, it’s important to change your sonic toothbrush head regularly. With colour-changing indicator bristles, these Premium Whitening brush heads let you know exactly when it’s time for a replacement. Designed for the Beurer SC50 Sonic Toothbrush, these brush heads are also compatible with all Philips Sonicare toothbrushes*. The Premium Whitening is cleverly designed with raised central bristles that polish while you brush for a whiter clean. On average, a sonic toothbrush head lasts around three months, so this pack of four will keep you covered for a full year.
