Abstract: An interproximal toothbrush and method for cleaning, irrigating and medicating a sub-gingival region with the same are disclosed. The interproximal toothbrush has outer and inner V-shaped portions having outer and inner working surfaces which form intersections at the distal ends from the spines, and bristles extending from the intersections which clean the deeper portions of the sub-gingival region between the teeth and gum. At least one aperture may be provided in at least one of the working surfaces such that irrigation fluid or a medicating, antibacterial or other cleaning agent may be dispensed from the aperture and be guided by the bristles to the sub-gingival region.

Abstract: A method of irrigating and cleaning a sub-gingival region is provided by guiding a sub-gingival periodontal irrigator of a flexible material into an interproximal region. The sub-gingival periodontal irrigator has outer and inner V-shaped portions having outer working surfaces and inner working surfaces which intersect at their distal ends from the spines, such that a hollow space is present therebetween. Irrigation fluid, medication or antibacterial agents may be dispensed through at least one aperture in at least one working surface to the sub-gingival region.
