The Bixdo W60 electric toothbrush is designed to provide users with teeth whitening benefits during use. The bristles incorporate a novel optical fiber material, featuring a tiny optical fiber core at the center of the light-conducting bristles with a diameter of either 8 micrometers or 50 micrometers. The addition of gum-protective bristles not only contributes to teeth whitening but also ensures thoughtful protection for the gums.
