Petsmile is the only VOHC approved toothpaste for you pet with Calprox. Veterinarians choose Petsmile because of the high-quality ingredients that promote white teeth and healthy gums. The VOHC recognizes that Petsmile meets the highest standards for your petàoral health. Using Petsmile toothpaste and brushing daily will significantly improve your pets dental health. Petsmileàproprietary formula Calprox is clinically proven to inhibit plaque and tartar buildup, while whitening teeth by gently dissolving the protein pellicle. The protein pellicle is the thin bio-film that forms on the surface of the teeth, to which plaque, bacteria, and stains adhere. Removing the pellicle leaves your petàteeth cleaner and whiter while improving hygiene, gum health and providing kissable fresh breath. The no-brushing required formula makes it easy to improve and maintain even the fussiest pet's oral health. Simply apply Petsmile toothpaste on your cat or dog's teeth and let their tongue do the rest. Your pet can immediately eat or drink after applying Petsmile toothpaste. For best results, we recommend brushing your pet's teeth with our Professional Pet Toothbrush once or twice a day. The great flavors, Rotisserie Chicken, Say Cheese, & London Broil will keep your pet looking forward to their next brushing.
