An interdental brush has a handle with a helix style shape, as well as sections of long and short bristles to maximize plaque removal. The handle has a first end, a second end and a length between the first and second ends. The handle defines a longitudinal axis extending through the handle along the length. A brush extends from the handle and includes a stem projecting along the longitudinal axis and a set of bristles extending laterally outwardly from the stem. Each of the bristles has a bristle length from the stem to a bristle tip, the bristle tips collectively defining a bristle profile. In one embodiment, the bristle profile alternates along the stem between valley sections of short bristle length and mountain sections of long bristle length. The handle includes a grip portion along the length, and the grip portion is shaped such that it is twisted about the longitudinal axis in the manner of a helix.
