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 cat.

And only Crunch 'n Clean treats have this unique coating. It’s what makes our treats a more effective way to easily care for your cat’s teeth between brushings and professional cleanings. It’s clinically proven to block tartar build up for cleaner teeth. And, it’s the reason vets agree Crunch 'n Clean is a treat you can feel good about giving your cat.


Proven Effective, Proven Safe
The ingredient behind DentaShield® technology, Sodium Hexametaphosphate, has been used for decades and is proven safe for your cat. It even breaks down into nutrients that keep her healthy.
        How DentaShield® Works
         STEP 1: Coats Teeth
        •	As your cat 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.
