Tusks, like other teeth, have a soft center surrounded by hard dentin primarily composed of calcium hydroxyapatite with smaller amounts of calcium carbonate, calcium fluoride, magnesium phosphate, and ossein. A hard durable enamel forms a smooth outer surface. Tusk has been used to make sculptures, handles, and other items."@en ;
