Clinically proven plaque removal with the Proxabrush® Handle and Refill System. Patented design to easily and securely load brushes. Antibacterial bristles keep the brush free of germs. Dual ended to hold more than one size of refill.* Our unique Proxabrush® Handle & Refill System has been designed to simplify cleaning between your teeth. Interdental cleaning is very important. Plaque and food particles can easily accumulate in the spaces between teeth, and this can eventually lead to gum disease. Comfortable and easy to hold, the GUM® Proxabrush® Handle & Refill System enables you to clean parts of your mouth that a regular toothbrush cannot. &
