Activity Introduction

Quick summary:

A fierce war is raging in the deepest darkest region of… your mouth! The Sneaky Sugar Army leads its attack on the Royal Teeth.

Who will save them?

Fortunately, the Guardians of the Gums are on hand to defeat plaque wherever it rears its ugly head. These heroes don’t need superpowers to take care of teeth, and neither do students!

This lesson is an accessible, engaging and informative way to get young students thinking about oral hygiene and dental care. Each Guardian has a unique role in taking care of teeth, enabling students to create strong associations with their own oral hygiene routines.
