The Jordan gum protector toothbrush 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.
