Microhydrin
Microhydrin - Best Dental Support Ever for Dogs and Humans 
Did you know that commercial toothpaste (for us and our animals) is often cited as a possible contributor to cancer?
Microhydrin is a remarkable negative ion free radical agent product. I highly recommend it for cleaning your and your dog's (and cat's too!) teeth. Just pull the gelcap apart and moisten the powder slightly with water, then use like a toothpaste. It heals all mouth wounds and gum problems, almost overnight! You'll want to use this yourself when you are experiencing plaque or gum problems of your own.
You'll be astounded at the results. But, along with it's healing properties, you'll also be glad to know it does not contain fluoride, sodium lauryl sulphate, saccharin, preservatives, animal ingredients, animal sweeteners, artificial color or flavor.
Caution: MicroBrite toothpowder (with microhydrin ingredient) is ok for you but not for your animals -- it has xylitol which is bad for doggies.
