    Abstract: A method of treating teeth and gums within an oral cavity including treating the accessible surfaces and hard-to-reach surfaces of the teeth and gums. The method includes providing an oral care composition including a therapeutic amount of sodium bicarbonate, providing a tool that generates hydrodynamic power, and applying the oral care composition to the accessible surfaces and the hard-to-reach surfaces of the teeth and gums and generating hydrodynamic power within the oral cavity. The combination of the oral care composition and the hydrodynamic power more effectively removes biofilm from the accessible surfaces and the hard-to-reach surfaces of the teeth and gums.

    Abstract: A method of making interdental cleaners includes forming a slug by extruding material in a direction of extrusion to form a first slug portion having a generally rectangular first cross-section and a second slug portion having a tapering second cross-section that extends away from the rectangular first cross-section. The method also includes stamping the slug substantially perpendicular to the direction of extrusion to form a plurality of cleaner blanks. The stamping forms the first slug portions into handle portions of the cleaner blanks, and the second slug portions into shaft portions of the cleaner blanks. The shaft portions include two pairs of converging surfaces that taper toward each other to define a point. The method also includes attaching cleaning members to the ends of the shaft portions.

    Abstract translation: 一种制造齿间清洁器的方法包括通过在挤出方向上挤压材料形成块状物以形成具有大致矩形的第一横截面的第一块状部分和具有渐缩的第二横截面的第二块状部分，该第二块状部分远离矩形 第一个横截面。 该方法还包括基本上垂直于挤压方向冲压块塞以形成多个清洁器坯料。 冲压将第一块部分形成到清洁器坯件的手柄部分中，并且将第二块部分形成为清洁器坯件的轴部分。 轴部分包括两对会聚的表面，它们彼此逐渐变细以限定一个点。 该方法还包括将清洁部件附接到轴部的端部。
