Role of enamel is to

  1. Give basic shape to the teeth
  2. Connect crown of tooth with its root
  3. Masticate the food
  4. Form bolus

Answer

(3) Masticate the food

Solution

Enamel is the hardest substance in the human body and covers the crown of the tooth.

As per NCERT, the hard chewing surface of the teeth, made up of enamel, helps in the mastication of food.

Bolus is formed by the tongue and saliva, not by enamel; dentine gives the basic shape to the tooth.

The role of enamel is to masticate (chew) the food.
