Description. Tartar, also called calculus, is a hard mineral substance that binds to the teeth. Tartar collects on tooth surfaces, including between teeth, as well as at or beneath the gum line.Although tartar can develop at all ages, it becomes more common as children age.hen not properly removed by brushing and flossing, plaque mixes with minerals naturally found in saliva and hardens to form a cement-like shell. As tartar builds on the tooth surface, it creates more surface area to which plaque may cling, aggravating the problem.
