An interdental brush includes a handle, a stem member extending from the handle and at least one set of bristles extending radially from the stem member. The set of bristles includes a bristle pair that defines an angular brush gap. According to a method for cleaning an interdental space and corresponding periodontal pockets using the interdental brush, the interdental brush is aligned with the interdental space such that the angular brush gap is aligned with the gingiva of the interdental space. The interdental brush is further inserted into the interdental space, such that the gingiva is received within the angular brush gap and a bristle pair of the interdental brush extends into the periodontal pockets.
