In Year 4 we conducted a science experiment where we used plaque disclosing tablets to identify areas on our teeth that had collected plaque during the day.
It was a messy and enlightening experience! We spotted quite a few areas on our teeth which we had missed – mainly the parts which we realised were difficult to reach with our toothbrushes. We learned that we need to concentrate on cleaning our teeth in these particular areas in a circular motion.
