For me I love HealthyMouth and the CET Dental Chews. So far I have not had to do any dental cleaning on Buster other than the brushing. He will be four in July and his yearly visit to his Vet dentist (he retained his baby canines so we went to a Vet dentist for the surgery) will be in May. I really love the Healthymouth. Here is a great product comparison chart from Healthymouth
