Primary Constituent of Enamel of Our Teeth


  • Calcium Phosphate: The primary constituent of enamel in our teeth is calcium phosphate, specifically hydroxyapatite. Enamel is the hardest tissue in the human body and is made up of about 96% hydroxyapatite crystals.

  • Importance of Calcium Phosphate: Calcium phosphate provides the enamel with its strength and durability, protecting the teeth from wear and tear, as well as acid erosion.

  • Role in Tooth Structure: Enamel covers the outer layer of the tooth and acts as a protective barrier against bacteria and other harmful substances that can cause tooth decay.

  • Maintaining Enamel Health: Consuming foods rich in calcium and phosphorus, as well as maintaining good oral hygiene practices, helps in keeping the enamel of our teeth strong and healthy.
