    enamel consists primarily of Calcium phosphate and calcium carbonate. Enamel, the hardest substance in the body and the richest in calcium salts (about 95% of dry weight).

    Dentin, a calcified connective tissue that gives the tooth its basic shape and rigidity. it is harder than bone because of its higher content of calcium salts (70% of dry weight)

    Therefore, I think enamel has the most calcium salts.
