Specially designed to allow effective cleaning of all interdental spaces that are difficult to access for conventional brushes. It adapts to Trio Compact and Clinic Flex wires and is available in 4 sizes. Each size has its corresponding colour, with a specific wire diameter (between 0.38 and 0.80 mm) and a specific bristle diameter (between 1.9 and 8 mm) to adapt to all sizes of interdental spaces. Bicolour bristles: white to reveal sensitive gums in case of bleeding, and black, thinner, to facilitate the insertion of the brush and visualize the removal of bacterial plaque.
