Tartar control toothpaste cannot remove previous tartar build up. Only a trained dentist or dental hygienist can scrape away the hardened calcium above and below the gumline. What this toothpaste does is halt the progress of the destructive chemicals responsible for the creation of tartar. The tartar cycle begins with food. When food particles are allowed to remain on the teeth after eating, bacteria begins to feed on them. These living organisms excrete acids that leech out calcium from the tooth enamel. A process called demineralization. Eventually, this process creates cavities and fissures in the tooth. This compound of calcium and acid combines with oxygen to form a substance called calcium phosphate. Calcium phosphate tends to bond with existing enamel along the gumline and work its way up the tooth. This is the hard, yellowish material that must be scraped away with metal tools. Calcium phosphate will continue to form as long as the cycle of acid production and demineralization remains unchecked. Brushing with regular toothpaste removes the acid deposits and food particles, but the tartar will remain.
