Before understanding the mechanism and working we must understand the materials used in that brush. The brush is built up with a titanium battery in the handle of the brush. The battery is connected with a titanium rod that runs throughout the brush.
Now the working procedure starts with the brushing of teeth. We need to get a little bit of moisture in our hands and touch the metal band which helps in creating a closed circuit. While brushing, the ion charge comes into play, which helps change our teeth’ polarity.
