i used to be lazy to brush my dog's teeth daily; and then i started noticing that her back teeth have tartar build up. i freaked out because i don't want to put her under for cleaning; so i started brushing daily with CET toothpaste vanilla/mint and then used bluto's yummy gel that someone recommended; also i add some plaque-off powder with her food; it had made a huge difference; now she still have some on her teeth but i can see that they are going away. good luck
