Indeed in this field I have an idea that there is no perfect product. The brushes which at first glance appear to be satisfactory, deform rapidly or remain stuck in the interdental spaces. The toothpicks DenTek has a Mentole floss that certainly was not long but is very convenient for places usually inaccessible hard, and the toothpick tip has longevity in all tests. Also suitable for this tip to all the interstices little meadows and mania in two different directions of introduction. Overall, I am satisfied with the product.
