this is written on the box..."The Braun Oral-B interclean is an innovative method to remove plaque from between teh teeth - effective in reducing gingivitis, but easier to use than dental floss..." "the tip (of the product) is simply pointed at the interdental spcae, along the gumline, and the sliding switch activated. The long neck enables easy reach of all spaces...when the switch is activated, the mint-flavoured filament glides into the interdental space and spins at 6500 rpm. Its centrifugal action disrupts and removes interdental plaque gently, effortlessly and in seconds..."
Anyway, I've been using it for 2 days, it's all right....I think it disrupts plaque, but not so good at removing it. It's fun to use though🙂
