Abstract
An interdental foam brush with an elongate non-conductive, galvanic shock free stem having a boss, the stem having a brush support portion extending from the boss in the distal direction to a preferably rounded distal tip and a flexible handle engaging portion extending from the boss in the proximal direction. The brush support portion including its distal tip and the boss being enclosed in resilient, open-cell polymeric foam. The outer surface of the brush is tapered and converging in the distal direction. The boss is a stop means for limiting movement of the brush portion between interdental surfaces, and the brush support portion has a length approximating the width of a rear molar. The brush support portion has a diameter providing a brush support surface for effective cleaning while permitting passage of the brush between interdental surfaces. The foam has a hardness and pore density providing effective cleaning between interdental surfaces is achieved. Another aspect is a combination of the interdental foam brush described above and a handle. The interdental foam brush can be impregnated with a pharmaceutically effective amount of at least one agent for treating the gums or t…
