These 4 unique replacement brush heads are designed to maximize the cleaning and whitening functions of the Sonic Blue toothbrush. A clean brush head allows greater emission of blue light from your Sonic Blue toothbrush, for maximum whitening.
The unique over-sized shape includes rubber gum massagers, which clean teeth thoroughly, up to the gumline where stains can hide, and two kinds of bristles. Antibacterial bristles help reduce germ build-up on the brush head, and color-changing bristles indicate when it’s time to replace the brush head.
