Gentle care with strong results. Curaprox CS 5460 “ultra soft” toothbrush Curaprox toothbrushes are gentle on gums and toothache, but effectively clean the plaque. CUREN® bristles do not lose their elasticity even when moistened, so they are fine and dense. This is a very gentle "ultra soft" toothbrush for effective cleaning, especially protecting the health of the gums. The slightly concave head and angled handle make cleaning easier even in hard-to-reach places.
