100% silicone replacement brush head for all ISSA electric toothbrushes (except ISSA micro/play). Soft and flexible silicone bristles won't scratch tooth enamel or damage gum tissue, making it perfect for both children's softer tooth enamel and sensitive gums or for adults who prefer a smaller brush head. Made from medical-grade silicone, the ultra-hygienic brush head lasts for 1 year.
