GUM Go-Betweens Proxabrush Cleaner Dual-Ended Handle 12/box

All GUM Proxabrush refills now feature new triangular-shaped bristles that penetrate and remove up to 25% more plaque compared to conventional round bristles (in lab study). The bristles incorporate a patented antibacterial agent. For added comfort, a light nylon coating is applied to each brush to help prevent galvanic shock.
