Dispersed throughout the plastic material is at least one anti-microbial active compound such as a halogenated hydrocarbon, a quaternary ammonium salt or combinations thereof. Preferably the plastic material is a low density polyethylene. Toothbrushes of the present invention inhibit the growth of bacteria and other micro-organisms thereby avoiding the possibility of infecting oral gums.
