Between visits, pets should be given Dental Fresh every day. Dental Fresh is the “world’s first toothbrush in a bottle.” Its effective formula eliminates plaque, tartar and odor causing organisms. Dental Fresh contains chlorine dioxide and baking soda in a self-regulating formula that activates anytime bacteria is present. It helps kill germs in your pet's mouth and eliminate slime that forms in your pet's bowl. One 8 ounce bottle of Original Formula Dental Fresh, Expiration date of 04/2025.
