What's the difference between dentine and ivory?

Dentine


Definition:

  • (n.) The dense calcified substance of which teeth are largely composed. It contains less animal matter than bone, and in the teeth of man is situated beneath the enamel.

Ivory


Definition:

  • (n.) The hard, white, opaque, fine-grained substance constituting the tusks of the elephant. It is a variety of dentine, characterized by the minuteness and close arrangement of the tubes, as also by their double flexure. It is used in manufacturing articles of ornament or utility.
