If not treated, can calcify into tartar, something that cannot be brushed away from the teeth. Instead, a vet needs to remove tartar with anesthesia and ultrasound. If the tartar remains untreated, it can lead to infections being passed in the animal's body, which can damage the heart, lungs, liver and adversely affect renal function. Our goal is to offer natural products to supplement your pet's dental and oral hygiene routine.
