Jordan Gum Protector Soft W/hc is with deep clean bristle technology and pressure control, protects teeth and gums against damage. To combat the problem of brushing too hard the toothbrush will bend and give way with a noticeable 'click'. The mechanism sits in a joint in the handle and will be felt as a click under your thumb when you brush too hard. When that happens, you will automatically ease the pressure and treat your teeth more gently.
