Abstract: A toothbrush combination including a whistle, horn, or other wind operated device releasably connected to or molded as part of the handle. The mouthpiece of the sound device can be aligned longitudinally with the toothbrush handle with the mouth engaging part facing opposite from the brush location or alternately the mouthpiece can be formed at a 90.degree. angle to the longitudinal axis of the toothbrush handle and located intermediate the brush and the opposite end of the handle. Preferably the distal end of the handle is shaped to fit a standard toothbrush holder for storage in an upright position. When so stored, liquid is free to drain from the sound chamber for the latter to be air dried to reduce bacterial growth. The sound device is preferably sculptured to form a figure, logo, character, or object which sculpture also functions as a mouth guard or safety device against inward impact forces when blowing.
