Calculus (tartar) control
Calculus, sometimes referred to as tartar, can build up on the surface of the teeth. When dental plaque is not cleaned away, excess minerals found in the saliva enter the plaque and cause it to calcify (harden), creating calculus. Calculus cannot be removed from the teeth with a toothbrush and must be removed by a dental practitioner who performs a professional cleaning of the teeth, known as a scale and clean.
Ingredients such as pyrophosphates, zinc citrate and sodium hexametaphosphate can help to reduce the build-up of calculus.
