"ProDen Plaque Off is an easy way to help care for your pets teeth, and when used regularly it can help to control tartar and bad breath. PlaqueOff does not have to be applied directly on the teeth, but rather comes in a powder form that is sprinkled on your pet’s food. When the ingredients are absorbed into the blood via the digestion and enters the saliva, they prevent plaque by affecting the ability of plaque to ‘stick’ to surfaces in the mouth. Existing tartar also then becomes porous, and loosens by itself or can be easily removed by brushing or cleaning. It is made from seaweed, and contains 12 vitamins, 13 minerals & trace elements and is rich in natural iodine."
