This toothbrush is quite simply a stroke of luck for people with tooth cleaning damage. Using pressure is almost impossible with the Curaprox ATA. Its round handle had no thumb depression and motivates users to grip only with their fingers thereby helping to keep pressure to a minimum. Its small head is ideal for reaching all planes and faces of all your teeth. It has 4860 bristles on thqat small head and as a result is soft and gentle. Developed in cooperation with dental specialists at the University of Berne.
