Hartz Crunch ’n Clean
What Is DentaShield?
Much like fluoride aids in better oral care for you and me, DentaShield® was developed to promote better oral care for your dog.

And only Crunch 'n Clean biscuits have DentaShield®. It’s what makes our biscuits a more effective way to easily care for your dog’s teeth between brushings and professional cleanings. It’s clinically proven to reduce tartar formation for cleaner teeth.


Proven Effective, Proven Safe

The ingredient behind DentaShield® technology, Sodium Hexametaphosphate, has been used for decades and is proven safe for your dog. It even breaks down into nutrients that his body can use.
        How DentaShield® Works
         STEP 1: Coats Teeth
        •	As your dog chews, DentaShield® coats teeth with a protective barrier.
        STEP 2: Blocks Tartar
        •	This protective barrier BLOCKS new tartar formation.
        STEP 3: Lasts Longer
        •	Teeth are left cleaner and stay cleaner, longer.

        (DR. STOOKEY BIO AND PHOTO)
        DentaShield®  was developed at the Indiana University School of Dentistry by a team of researchers led by Dr. George Stookey, a pioneer in fluoride research and preventive dentistry for humans and animals.

        Dr. Stookey has authored more than 230 publications in scientific journals and made invaluable contributions to scientific meetings, text and reference books. He holds almost 20 U.S. and foreign patents.  And, in 2002 he received the International Association for Dental Research Distinguished Scientist Award for Dental Caries Research.
        Dr. Stookey continues his research today with primary interests in fluoride pharmacology, the use of fluoride to prevent dental caries, new technologies for the early detection of dental caries, and measures for calculus prevention.
