How clean are our teeth?

This term we have been studying how to look after our teeth.
We used disclosing tablets, which dyed the children's mouths showing any food particles or plaque on their teeth. Their teeth weren't really as dirty as they appear, the dye needed to be rinsed off before they could see where the food or plaque remained. This will make them clean their teeth well in future!
