The Oral-B Criss Cross Medium Toothbrush is designed to provide effective and thorough cleaning for your teeth and gums. It features a unique criss-cross bristle arrangement that helps remove plaque and debris from hard-to-reach areas, leaving your mouth feeling fresh and clean. Criss Cross Bristles: The toothbrush head is equipped with criss-cross bristles that are arranged at different angles. This design helps the bristles reach deep between teeth and effectively clean along the gum line, targeting plaque and food particles in those areas. Medium Bristles: The toothbrush is labeled as "Medium," indicating that the bristles have a moderate firmness. Medium bristles strike a balance between effectively removing plaque and being gentle on the gums and tooth enamel. Comfortable Grip: The handle of the toothbrush is ergonomically designed to offer a comfortable grip, making it easier to hold and control during brushing.
