Display three stages of tooth decay -

  1. Plaque combines with sugar to form an acid
  2. Acid causes cavity
  3. When the cavity reaches the pulp - you get a toothache
Let your students complete the empty blank of tooth decay worksheet and make sure that they are correct.

Ask your students - What harms the teeth? It's food and bacteria - and if proper steps are not taken - it will lead to tooth decay.
