TOOTHBRUSH EXHIBITING THREE-DIMENSIONAL BRISTLE PROFILE AND END ROUNDED BRISTLES FOR IMPROVED INTERPROXIMAL CLEANING WITHOUT INCREASING GUM IRRITATION
摘要
A toothbrush is provided for achieving improved interproximal cleaning without increasing gum irritation. The bristles (118) of the toothbrush have a generally ''V'' shaped side profile. In addition, the exposed ends (120) of all of the bristles (118) are properly end rounded. The dimensions and shape of the ''V'' shape fall within a certain range, as does the stiffness of the bristles (118). These characteristics allow the bristles (118) to penetrate into the interproximal areas with enough force to effectively clean these areas without causing irritation to the user's gums.
