Gum and tooth enamel damage from brushing is a more serious issue than cavities. Up to three out of four individuals brush too vigorously. To address that issue, the toothbrush will bend and give way with a noticeable "click" when you brush too vigorously. When you brush too vigorously, the mechanism, which is located in a handle joint, will click beneath your thumb. You will instinctively reduce the pressure and give your teeth a softer treatment when that occurs. Additionally, the brush head features ultra-thin tapered bristles that reach farther between teeth than regular bristles and guarantee effective and gentle tooth cleaning along the gum line. The following degrees are available for Clinic Gum Protector.
