Is Tooth Enamel Harder Than Your Bones?

Yes! Surprisingly, tooth enamel is the hardest substance in your body! Crazy?

Tooth Enamel Structure

  • Highest percentage of minerals, primarily, hydroxyapatite (crystalline calcium phosphate).
  • Semi translucent
  • Contains two proteins: amelogenins and enamelins
  • Soft tissue called dentin (responsible for color and support of enamel)
  • Only tissue that is completely acellular
  • Forms a protective covering
  • Composed of organic and inorganic substances

If your enamel is destroyed, your body does not make more to replace it. Unlike your bones, for example; enamel does not contain any living cells, so it cannot regenerate.
