A toothbrush is described having a contoured head that is suitable for cleaning teeth with orthodontic brackets. The toothbrush head has a ridge located a direction transverse to the longitudinal axis of the toothbrush. Bristles may be attached to the surface of the contoured head and ridge to extend outwardly therefrom. The bristles target the gingival margin, interproximal areas and the surfaces of the orthodontic bracket base as well as the remaining exposed surfaces of the tooth for cleaning.
