In this section students explore how to prevent dental decay (caries). Students will look at the sugar in their own diets and the amount of sugar contained in common drinks. They are introduced to looking after their teeth and mouths to keep them healthy and prevent infection.

Activities include:

  • Health diet diaries that facilitate learning on how “sugar attacks” are affecting students’ teeth.
  • A sugary drinks exercise where students measure and compare the amount of sugar in beverages they commonly consume.
  • A “Brushing diary” exercise that facilitate discussion around a tooth brushing as well as other messages around successful oral hygiene.

The video provides detailed instructions to students on tooth brushing in the home.
