Curaprox Prime Start Cps 09 Intermediate Brushes Yellow 5pcs CPS prime are the best and thinnest brushes on the market with unsurpassed durability. Even the narrowest interdental spaces are perfectly and non-traumatically cleaned. The brush reaches where it is needed to prevent tooth decay on the sides of the teeth, gingivitis and periodontitis. The excellent quality of CPS prime ensures a perfect result with a single move: inside-out and ... END! Thin hairs reach all difficult points and have a long length to effectively clean the interdental space. Joint brushes with short bristles, which do not adequately cover the gaps, are ineffective. Food scraps remain, the plaque is not removed and the unpleasant consequences are inevitable. CURAPROX CPS brushes perfectly cover the gaps between the teeth: Thanks to the special shape of the brush and the composition of the fibers, they open in the shape of an umbrella between the teeth and are spread out to fill all the gaps. They clean effectively and non-traumatically.
