After I had around me for years plagued with dental floss and progressive periodontal disease was unstoppable, I had changed the dental hygienist. This told me to interdental brush. Then came a time when I had gepieckst, with metal ends regularly to the gums and I switched annoyed to dental woods. A friend had recommended to me then the Curaprox. The holders were me right from the start well in the hand and I clean regularly with two different sizes (and 2 brackets, so I do not have to change every time), relatively quickly and without Pieckser. Since then, my gums has already recovered very well that I could go to the annual dental hygienists from haljährlichen-cycle. The relatively expensive product is now at a very good cost-benefit ratio. Therefore, I have not bought this for my third holder travel accessories.
