Description: The ELGYDIUM Clinic Mono Compact toothbrush effectively removes plaque. The length of the brush core increases with its size. Flexible and durable, it allows you to reach hard-to-reach places. Two-tone bristles: white bristles will allow you to see sensitive gums when they bleed; I am glad that the black bristles make it easier to insert the brush into the interdental space and make the removed plaque visible. The blister contains 4 toothbrushes of the same size. How to use: Intended for cleaning interdental spaces and elements of orthodontic appliances. Rinse the brush after each use.
