Beaphar Toothpaste counteracts plaque and prevents tartar formation, resulting in better oral health. The tasty liver formula means dogs and cats will love it. Beaphar Toothpaste is fluoride free and contains two enzymes, protease & glucose oxidase. Protease destroys the protein structure of plaque before it binds with calcium to become tartar. Glucose Oxidase transforms glucose into harmless gluconic acid. This process produces a small amount of hydrogen peroxide, which is an antibacterial and will kill dental bacteria.
