The chemical substance present in bones and teeth is Calcium Phosphate or Ca₃(PO₄)₂.

• Calcium phosphate is fundamental to the formation of bone and teeth.
• It is essential for achieving optimal peak bone mass in the first 2–3 decades of life and for the maintenance of bone in later life.
• Bones:-
  • Bones are mostly made of collagen, a type of protein.
  • Calcium phosphate, a mineral, is the other main component of the bones.
  • Collagen gives the bones a soft framework, while calcium phosphate is what makes them hard and strong.
  • Bones are made of living tissues, so old bone tissue is broken down and removed, and then new tissue is created to replace the old.
