At this time - have your students complete parts of the tooth worksheet independently. Review it with them.

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.

So - what can you do to avoid tooth decay?

  • Regular brushing
  • - it will remove plaque from your teeth and your mouth

  • - it will remove hard to reach food between your teeth
  • Eating right
  • - nutritious food will keep your inner part of the tooth healthy
